Assemblage structure and ecological functions of dung beetles in exotic pastures in the Southwestern Amazon - Anderson Puker; Amanda Eloise Machado de Souza; Renato Portela Salomão; Pedro Giovâni da Silva; Fernando Zagury Vaz-de-Mello; César Murilo de Albuquerque Correa (International Journal of Tropical Insect Science, 2026)
The implementation of exotic pastures in the Amazon causes drastic negative impacts on its biodiversity. Nevertheless, some species with the ability to colonize pastures may provide important ecosystem services for livestock development in tropical pastures, as in the Amazonian biome. In this study, we evaluated the diversity and assemblage structure of dung beetles, as well as measured their ecological functions (i.e., dung removal and soil excavation) in exotic pastures in the Southwestern Amazon. Dung beetles were sampled using pitfall traps baited with fresh cattle dung, and their ecological functions were measured using experimental arenas during the rainy season. A total of 123 individuals were collected, belonging to five genera and nine species of dung beetles. Dung beetle assemblage had more species of small to medium body size (< 8 mm), with only two species classified as large-bodied. Large and small telecoprids were the most abundant functional groups. The mean (± SE) values for dung removal and soil excavation were 10.9 ± 2.33 g and 15.2 ± 4.22 g, respectively. These findings indicate that only a limited number of dung beetle species are able to colonize exotic pastures in the Southwestern Amazon, predominantly those of small to medium body size, which leads to a reduction of key ecological functions in these environments.

Response of Tetranychus urticae (Acari: Tetranychidae) to natural products - Darliane Evangelho Silva; Rita Tatiane Leão da Silva; Antônio de Almeida Paz Neto; Joseane Moreira do Nascimento; Laís Rosário da Luz; Luiz Liberato Liberato Costa Corrêa; Guilherme André Spohr; Juliana Granich; Noeli Juarez Ferla (International Journal of Tropical Insect Science, 2026)
The two-spotted spider mite, Tetranychus urticae (Acari: Tetranychidae), is a cosmopolitan pest of numerous crops, including grapevines, where outbreaks cause leaf chlorosis, necrosis, defoliation, and yield reduction. Intensive use of synthetic acaricides has led to resistance and negative effects on non-target organisms, reinforcing the need for sustainable alternatives. This study evaluated the effects of three plant-based products (neem oil, a garlic-based formulation, and a citric acid–pyroligneous extract formulation) on repellency, oviposition, and mite abundance of T. urticae under laboratory conditions. Bean plants ( Phaseolus vulgaris ) were used as a substrate, and treatments were applied at field-recommended concentrations. After 24 h, all formulations significantly reduced oviposition and mite abundance compared with the control. Neem oil showed the strongest reduction in oviposition, whereas the garlic-based formulation exhibited the strongest repellent effect. The garlic-based and citric acid–pyroligneous extract formulations also inhibited oviposition, indicating complementary potential in integrated mite management. These findings highlight the potential of natural product-based formulations as ecological tools for controlling T. urticae , supporting their integration into sustainable viticulture and other cropping systems. Further studies should assess their performance under field conditions and their compatibility with predatory mites to ensure ecosystem balance and long-term pest suppression.

Diversity, distribution, and functional traits of bee assemblages across habitat types in Matobo National Park, Zimbabwe - Gugulethu Tarakini; Robert Musundire; Tafadzwa Matengo; Clever Watakama; Pelton Mumba; Tawanda Tarakini (International Journal of Tropical Insect Science, 2026)
Despite growing global interest in pollinator conservation, bee community responses to habitat heterogeneity remain poorly documented in protected semi-arid landscapes of southern Africa. This study investigated how habitat type influences bee community structure and functional traits within Matobo National Park, Zimbabwe. Bees were surveyed at 16 sites across four habitat types (granite kopjes, woodlands, grasslands, and riverine woodlands), yielding 1026 individuals representing 75 species; however three sites per habitat (12 sites total) with equal sampling effort were used for balanced statistical comparison via generalized linear models, PERMANOVA, and indicator species analysis. Species richness (χ²=16.55, df = 3, p < 0.001) and diversity (F = 7.68, df = 3,8, p = 0.010) differed significantly among habitats, with granite kopjes lower than grassland ( p < 0.001, p = 0.005), while abundance ( p = 0.068) and community composition (PERMANOVA R²=0.389, p = 0.055) did not. Functional traits differed more strongly with granite kopjes showing fewer long-tongued bees (χ²=18.03, p < 0.001) and a distinct nesting-strategy composition dominated by cavity-nesters (Rao–Scott F = 6.94, p < 0.001). Twenty-one of twenty-seven species identified to species level had no recorded observations in Zimbabwe on iNaturalist. The study also recorded Braunsapis otavica , a new country record for Zimbabwe based on CAB- GBIF data, bringing the total documented Zimbabwean bee species to 439. Functional trait composition appeared more sensitive to habitat variation than taxonomic diversity, suggesting structurally distinct habitats are important for maintaining functional as well as taxonomic diversity in protected semi-arid landscapes. Chao1 estimates indicated sampling completeness of only 54–65% across habitats, so these patterns should be regarded as preliminary pending more intensive sampling.

Modeling the current and future potential distribution of Leptoglossus zonatus (Hemiptera: Coreidae) under climate change scenarios - Marinaldo Loures-Ferreira; Gildriano Soares de Oliveira; André Medeiros de Andrade; Jackson Paulo Silva Souza; Lucas Gabryel Maciel dos Santos; Ana Luíza Medrado Monteiro; Álvaro de Moura Goulart; Ricardo Siqueira da Silva (International Journal of Tropical Insect Science, 2026)
Leptoglossus zonatus is an economically important leaf-footed bug across the Americas, damaging several high-value crops. We assessed its current and future potential distribution using an ensemble species distribution modelling framework calibrated with climatic and topographic predictors and evaluated via spatial block cross-validation to reduce spatial autocorrelation. Future projections were generated for SSP2-4.5 and SSP5-8.5 using CMIP6 general circulation models (MIROC6 and MRI-ESM2-0) for mid-century (2041–2060) and late-century (2061–2080). Ensemble models showed high predictive performance and identified annual mean temperature and precipitation seasonality as dominant determinants of suitability. Projections indicated a spatial redistribution of climatic suitability, characterized by the expansion of marginally suitable areas and the contraction of moderate to highly suitable habitats, rather than a simple range expansion, especially under SSP5-8.5. Despite declining high-quality habitat, major agricultural regions currently affected by L. zonatus are expected to remain climatically suitable, albeit under increasingly suboptimal conditions. These results support climate-informed surveillance and adaptive pest management under ongoing climate change.

Habitat use and gut contents of Odonata (Insecta) larvae from streams in central Amazonia - Ulisses Gaspar Neiss; Renato Tavares Martins; Myckey Gonçalves; Neusa Hamada (International Journal of Tropical Insect Science, 2026)
The structure of aquatic invertebrate communities in Amazonian streams is influenced by substrate type, water velocity, and resource availability. In this study, we examined the diet and habitat associations of Odonata larvae across different substrate types in “ terra firme ” streams of Central Amazonia to better understand their trophic interactions and microhabitat use. Sampling was conducted in the Ducke and Uatumã reserves during the dry and rainy seasons of 2009, encompassing nine substrate types. A total of 992 larvae representing 36 species/morphotypes were analyzed for gut contents. Habitat association patterns indicated strong substrate specificity among taxa. Burrowing taxa were predominantly associated with sandy substrates, whereas other groups were mainly related to coarse or organic substrates in riffle and depositional habitats. These distribution patterns likely reflect morphological and behavioral adaptations related to substrate use and local hydrological conditions. Only 51.4% of larvae contained prey items in the foregut, comprising 27 categories and a total of 797 recorded items. The diet was dominated by Chironomidae, followed by Ephemeroptera and Trichoptera, indicating that prey consumption largely reflects resource availability in the benthic environment. Differences in prey composition among functional groups suggest that feeding is strongly influenced by microhabitat use, with sediment-associated larvae consuming mainly benthic prey, while those inhabiting more structured substrates exploited a broader range of food resources. No relationship was observed between larval body size and the number of prey items consumed. Overall, our results indicate that Odonata larvae in Amazonian streams behave predominantly as opportunistic generalist predators, with trophic interactions shaped by substrate heterogeneity and prey availability. These findings highlight the importance of habitat complexity in structuring both the spatial distribution and feeding ecology of aquatic predators, contributing to a better understanding of trophic dynamics and supporting conservation strategies for freshwater ecosystems in the region.

Trema micrantha extract for sustainable spider mite management - Eduarda Carriço; Ana Beatriz Mamedes Piffer Holtz; Caio Henrique Binda de Assis; Selma Garcia Holtz; Ronilda Lana Aguiar; Anderson Mathias Holtz (International Journal of Tropical Insect Science, 2026)
Given the increasing demand for sustainable alternatives to synthetic acaricides, this study evaluated the acaricidal activity of aqueous leaf extracts of Trema micrantha Blume (Cannabaceae) against adult females of Tetranychus urticae Koch, 1836 (Acari: Tetranychidae) under controlled laboratory conditions. Extracts prepared from dried and powdered leaves were tested at 2.0, 2.7, 3.6, 4.9, 6.6, and 9.0 g/100 mL, using distilled water plus Tween ® 80 as the control treatment. Mortality was recorded over 72 h in BOD-type climate chambers at 25 ± 1 °C and 70 ± 2% relative humidity. The extract caused concentration-dependent mortality, with estimated LC₅₀ and LC₉₀ values of 3.16 and 10.99 g/100 mL, respectively. These results demonstrate that aqueous extracts of T. micrantha have promising acaricidal activity against adult females of T. urticae and may represent a potential botanical tool for integrated mite management. Further studies are needed to evaluate additional developmental stages, sublethal effects, non-target safety, formulation stability, and field performance.

DNA barcoding and phylogenetic analysis of dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae) in North-Eastern Namibia - Mukendwa Hosticks Ndozi; Linnet Gohole; Isaac Mapaure; Emily Jepyegon Chemoiwa (International Journal of Tropical Insect Science, 2026)
Taxonomical Keys have been used in the identification of dung beetle species due to their cost-effectiveness and accessibility. The aim of this study was to determine the DNA barcoding and phylogenetic relations of dung beetles in north-eastern Namibia. Sampling of dung beetles was done using baited pitfall traps. The collected Dung beetles were preserved in DNA/RNA Shield solution. The genomic DNA was isolated using blood and tissue Quick-DNA Miniprep Plus Kit. COI universal primers were used for PCR amplification. The sequence FASTA files were aligned using the multiple alignments ClustalW software, and the Phylogenetic relationships by neighbour-joining analysis were performed using the MEGA12 software. A total of 62 DNA barcodes of dung beetle species were accomplished, from which 15 species from 27 sequenced samples were identified with a percentage of 95–100%, while 35 dung beetle sequences were not retrieved from the database. The neighbour-joining phylogenetic tree showed 9 species of the genera Onthophagus , Milichus , and Caccobius of the tribe Onthophagini separated from each other and grouped together with the bootstrap value (> 95%). The clustering examination divided the 32 species into three main clades, while two species appeared separately from the three clades. This study was the first report of DNA barcodes specifically for Namibian dung beetles. The DNA barcoding and phylogenetic analysis application for molecular identification in dung beetles provides valuable and accurate information which is useful for understanding their diversity.

Efficacy of Neem-Derived Silver Nanoparticles Against the Termite Odontotermes obesus - Zanib Bashir; Sadia Qayyum; Rukhsana Kausar; Abrar Hussain Mian; Sama Allah Khan; Kamran Alam; Bushra Rehman (International Journal of Tropical Insect Science, 2026)
Forests, which cover approximately 30% of the Earth’s land surface, are increasingly threatened by pests such as Odontotermes obesus , causing significant economic and ecological damage. The present study investigated the biosynthesis of silver nanoparticles (AgNPs) using Azadirachta indica (neem) leaf extract and evaluated their insecticidal efficacy against O. obesus. AgNPs were synthesized via a green approach and characterized using UV–Vis spectroscopy (peak at 419 nm), FTIR (functional groups confirming phytochemical involvement), XRD (face-centered cubic structure with a crystallite size of 14 nm), and SEM (spherical morphology with an average size of ~ 5 nm). Bioassays, including a filter paper choice repellency assay, contact-toxicity mortality assay, and behavioral tunneling and antifeedant assessments, were conducted using 20 termites per replicate with three replicates for each treatment. The synthesized AgNPs exhibited strong bioactivity, repelling 93.3 ± 2.35% of termites and causing 100% mortality at concentrations of 25 mg/L, 20 mg/L, and 15 mg/L within 50, 60, and 70 min, respectively. Lower concentrations (10 mg/L and 5 mg/L) resulted in mortality rates of 53.09% and 47.19%, respectively. Statistical analysis indicated significant effects of both concentration and exposure time on termite mortality ( p ≤ 0.05). Furthermore, AgNPs disrupted tunneling behavior and reduced feeding activity, with an antifeedant index of 78.1 ± 2.66%.These findings demonstrate that neem-derived AgNPs are a promising alternative bioinsecticidal agent for integrated forest pest management, offering effective repellency, rapid toxicity, and behavioral disruption.

Butterfly community (Lepidoptera) in a protected area of the Atlantic Forest, Paraná, Southern Brazil - Lucas Ramos Vieira; Anna Mara Ferreira Maciel; Norma Barbado; Carolina Yumi Shimamoto; José Adolfo Mota de Almeida; Marcos Magalhães de Souza (International Journal of Tropical Insect Science, 2026)
Butterflies (Lepidoptera) are important bioindicators of environmental quality, as they exhibit patterns of diversity and seasonality that may be directly related to environmental conditions and resource availability. Thus, this study aimed to conduct a butterfly fauna inventory and investigate community composition and structure across three seasons in a remnant of the Atlantic Forest at the Bela Vista Biological Refuge, municipality of Foz do Iguaçu, Paraná, Southern Brazil. Sampling was conducted from September 2021 to May 2022, with campaigns in autumn, spring, and summer. A total of 435 individuals were collected and distributed among 112 species from six butterfly families. The relative abundance of species suggests that autumn showed a more balanced distribution (H’ = 3.05), whereas spring exhibited lower diversity (H’ = 1.99), indicating a temporal shift in community composition and structure. The most diverse season was autumn, and no statistically significant difference in diversity was found between summer and spring. Therefore, the protection and management of areas such as the Bela Vista Biological Refuge are important for maintaining regional biodiversity, especially in regions threatened by agricultural and urban expansion.

Does dead wood availability drive abundance and biomass of wood-feeding termites in Caatinga dry forests? - Israel S. Silva; Alexandre Vasconcellos (International Journal of Tropical Insect Science, 2026)
Wood-feeding termites rely almost entirely on dead plant material as both habitat and food resource; therefore, their biomass and abundance are expected to reflect the availability of these detrital resources. This study investigated whether dead wood availability influences the abundance and biomass of wood-feeding termites in Caatinga dry forests. Sampling was conducted in seven areas, where standardized 10 × 10 m plots were established to quantify dead wood biomass and collect termites associated with woody substrates. Termites were counted and dried to determine dry biomass per unit area (m²). The relationship between dead wood biomass and termite abundance and biomass was evaluated using linear regression models and remained significant when accounting for the hierarchical sampling design. Dead wood biomass varied markedly among sites, ranging from 57.2 to 284.8 g·m⁻² (mean ± standard error: 218.3 ± 34 g·m⁻²). Termite abundance averaged 76.1 ± 14.5 ind·m⁻², while mean termite biomass was 0.0276 ± 0.0054 g·m⁻². A significant positive relationship was observed between dead wood biomass and termite abundance (R² = 0.77, p < 0.01), and also between dead wood biomass and termite biomass (R² = 0.62, p < 0.05). Our results emphasize that reductions in dead wood biomass, commonly associated with vegetation removal, directly affect termite abundance and, to a lesser extent, termite biomass, with potential implications for carbon and nutrient stocks and fluxes in seasonal dry forests.

Zootechnical performance and nutritional composition of dubia cockroach (Blaptica dubia) fed commercial poultry feed - Anna Luisa Rodrigues Gomes Batista; Gustavo dos Santos Gomes; Andrew Crump; Diego Azevedo Mota; Anderson Barbosa Evaristo; Jeanne Broch Siqueira; Thiago Vasconcelos Melo (International Journal of Tropical Insect Science, 2026)
Insects such as the dubia cockroach ( Blaptica dubia ) are promising alternative protein sources for animal feed, but there is a lack of management information on their commercial rearing. These cockroaches are fed fruit and vegetables, as well as the commercial feed of various species, most commonly poultry feed. This study aimed to evaluate the effects of four commercial poultry rations (Initial-T1, Growth-T2, Fattening-T3, Laying-T4) on the zootechnical performance and nutritional composition of B. dubia . The cockroaches were reared from nymph age to adult age (five-month experimental period) and given one of the four diets. Weight gain, consumption, feed conversion, apparent digestibility, and mortality were assessed. The cockroaches’ bromatological and mineral composition was analyzed. There was no significant difference in weight gain, consumption, feed conversion, or mortality between the treatments. The digestibility of the T4 feed (72%) was significantly lower than the others (78–79%). The crude protein content was lower in T4 (1.76 g/kg DM) and higher in T2 (3.98 g/kg DM), resulting in Ca: P ratios < 1:1 in all treatments. The diet also influenced the levels of Cu and Zn. Overall commercial poultry diets perform well for Blaptica dubia . However, they have an inadequate mineral profile (low Ca: P), requiring attention for using dubia cockroach as a live feed.

What is Ranatra macrophthalma Herrich-Schäffer, 1849 (Insecta: Hemiptera: Nepidae)?

Defining species boundaries or proposing synonymies remains a challenging task. In such cases, quantifying morphological or molecular variation provides critical support for developing robust taxonomic hypotheses. Within this framework, Geometric Morphometrics (GM) offers a quantitative and replicable approach for assessing shape variation. Here, we applied GM techniques to quantify variation in the apex and subapical tooth of the paramere (non-intromittent male genitalia) in selected species of Ranatra (Insecta: Hemiptera: Nepidae), aiming to clarify the taxonomic status of Ranatra bachmanni De Carlo, R. magna Kuitert, and R. macrophthalma Herrich-Schäffer, whose original descriptions were based solely on body size and coloration. A total of 100 male specimens were examined, including the holotypes of R. bachmanni and R. magna . Bidimensional shape data were obtained using four landmarks and 28 semi-landmarks plotted on the distal portion of the right paramere. The dataset was analyzed using exploratory approaches (boxplots, Principal Component Analysis [PCA], ANOVA, and discriminant analysis [CVA]). While centroid size differed significantly among species, shape differences were not statistically significant. PCA revealed substantial morphospace overlap, and CVA correctly classified only 47.5% of the specimens. Additionally, shape exhibited residual allometric effects, with smaller parameres, more frequently observed in R. macrophthalma , tending to have shorter apices. However, considerable variation was still present, and no interspecific differences were detected in the subapical tooth. Our findings support the synonymy of R. bachmanni and R. magna with R. macrophthalma , highlighting the importance of GM in solving taxonomic uncertainties.

Land use, flooding regime, and seasons differentially shape composition of beetle species in a semi-arid highland floodplain in Central Kenya - Jane M. Macharia; Mathias Becker; Helida Oyieke; Kai Behn (International Journal of Tropical Insect Science, 2026)
Biodiversity is threatened globally by human-mediated alteration of natural environment. This includes East African wetland ecosystems that are subject to agriculture expansion and intensification. Monitoring of biodiversity is crucial to understand and mitigate biodiversity losses. Beetles, while rarely studied, are potentially useful bioindicators due to their sensitivity to environmental changes. Our study aimed at investigating the influence of land use regimes (cropland, fallow, grazing land, pristine), as well as flooding regimes and seasonality on the abundance, composition, diversity, and occurrence of beetle species in the Ewaso Narok swamp, Kenya. Using pitfall traps and sweep nets over two years (2015–2016) in 42 plots each of six sampling dates, we recorded 2,145 beetles (20 families, 179 species). Conversely to our hypothesis, we only found weak effects of land use on abundance, diversity and species composition. Seasons, and individual sampling dates were more important, partly due to varying rainfall prior to the sampling. Heavy rainfall decreased abundance of ground-dwelling beetles, particularly in the wettest zone. Regarding individual species, most occurred across all land uses and did not show much specificity. However, among ground-dwelling beetles, some species demonstrated significant associations with land use intensity. For instance, disturbance tolerant Tenebrionids such as Zophosis abyssinica and Gonocephalum simplex were associated with high land use intensity (cropland/fallows), while predatory Staphylinid Philonthus circumcinctus was associated with grazing lands. Hence, selected species may act as bioindicators and may represent “winners” and “losers” of land transformations. These results support biodiversity monitoring and future wetland use planning.

Callosobruchus maculatus (Fabricius, 1775) is considered the main pest that damages stored Vigna unguiculata (L.) Walp grains. Control of this insect is usually achieved through the use of synthetic insecticides, whose residual effects pose risks to human health and the environment. Given the important economic losses caused by the infestations of this pest and the need to develop less harmful control methods, this study aimed to evaluate the insecticidal potential of essential oils (EOs) from Lippia thymoides Martius & Schauer, Lippia lasiocalycina Schauer, and Lippia insignis Moldenke against C. maculatus . The chemical constituents of the EOs were analyzed, and an in vitro bioassay was conducted using a concentration of 10 µL mL − 1 . Distilled water and a 1% Tween ® 20 solution were used as negative controls, and Lambda-cyhalothrin was used as a positive control. Insect mortality was recorded at 24 and 48 h after treatment. The results showed that among the tested species, L. insignis was the most effective, causing 100% mortality after 48 h. Subsequently, the EO of L. insignis was tested at five different concentrations (0.625, 1.25, 2.5, 5 and 10 µL/mL) to determine the median lethal concentration (LC₅₀), which was found to be 3.11 µL/mL. Based on this result, a concentration of 5 µL/mL was selected to assess the efficacy of two application methods: topical contact and exposure to contaminated surfaces. Both methods proved to be effective in controlling C. maculatus.

Syrphidae (Diptera) are ecologically important insects that contribute to pollination, biological control, and decomposition. However, in the Neotropical region, they remain one of the least studied Dipteran families due to a lack of specialists and high behavioral and taxonomic diversity. This study assessed the composition of adult syrphids in a protected area of the Brazilian Cerrado over a two-year period and evaluated the influence of climatic variables on their abundance, richness, and community structure. Sampling was carried out from October 2018 to August 2020 using passive (Malaise traps) and active (entomological nets) methods in two vegetation types: Cerrado sensu stricto and gallery forest. A total of 442 individuals representing 66 Syrphidae species were recorded. The genus Toxomerus Macquart, 1855 was the most abundant, with Toxomerus lacrymosus (Bigot, 1884) and Toxomerus laenas (Walker, 1852) as dominant species. Abundance was significantly higher in the Cerrado sensu stricto , whereas species richness did not differ significantly between vegetation types or in response to climatic variables, despite marked differences in species abundance and diversity. Temperature had a negative effect on both abundance and species composition. Despite differences in sampling effort, each method captured a distinct subset of the community, demonstrating their complementarity. These findings suggest that high temperatures may constrain hoverfly activity or survival and that differences between vegetation types play a key role in shaping community diversity. Therefore, the conservation of both open and forested habitats is crucial for maintaining Syrphidae diversity and the ecological services they support.

Efficacy of a single root drench application of thiamethoxam for the management of dubas bug and white date scale on date palms - Mokhtar Abdulsattar Arif; Salvatore Guarino (International Journal of Tropical Insect Science, 2026)
Date palms ( Phoenix dactylifera ) are a vital crop in the Middle East, particularly in Iraq, where infestations by the dubas bug ( Ommatissus lybicus ) and the white date scale ( Parlatoria blanchardi ) significantly threaten yield and fruit quality. This study assessed the efficacy of a single soil drench application of thiamethoxam (Actara 240 SC) for controlling these pests in two cultivars, Barhi and Brem, under field conditions. Treatments resulted in a substantial and sustained reduction in pest populations compared to untreated controls over a 120-day period. Residue analysis using gas chromatography demonstrated systemic absorption and gradual dissipation of thiamethoxam in leaves and fruits, with residues declining below detection limits by 120 days after treatment. The temporal correlation between residue decline and pest suppression underscores the prolonged protective effect of root drenching. These findings support the use of a single root drench as an effective, long-lasting, and potentially more sustainable pest management strategy that reduces the need for repeated foliar applications, thereby lowering labor and chemical inputs.

On the globally distributed genus Gryllodes Saussure, 1874 (Orthoptera: Gryllidae: Gryllinae) as a non-native presence in the Americas: taxonomy, morphology, bioacoustics, new records, and species distribution modeling - Riuler Corrêa Acosta; Rodrigo Antônio Castro-Souza; Oscar J. Cadena-Castañeda; Luiz Augusto Padilha Santos; Maria Kátia Matiotti da Costa; Edison Zefa; Rafael Dudeque Zenni; Gustavo Costa Tavares (International Journal of Tropical Insect Science, 2026)
Non-native insects are often inconspicuous organisms that can negatively impact the economy, biodiversity, and public health. Field crickets (Orthoptera: Gryllidae: Gryllinae) have historically been used as a food source for livestock, pets, and humans—a practice that likely facilitated the spread of certain species into urban centers and non-native habitats. Although rarely cited as invasive, species like Gryllodes sigillatus and Gryllodes supplicans are now widely distributed across diverse environments. Based on recent fieldwork in Brazil, Guatemala, Costa Rica, Colombia, and Ecuador, we conducted morphological and acoustic analyses that confirmed the presence of G. sigillatus in all five countries and documented the first record of G. supplicans in Brazil. We also reassigned Gryllodes flavispina to Loxoblemmus , limiting Gryllodes to two recognized species. This prompted a reassessment of diagnostic traits and the development of global distribution models. Our findings revealed consistent acoustic and morphological differences between the species, facilitating future detection and monitoring. Biogeographic models predict a broad potential distribution and multiple zones of sympatry. Although Gryllodes species are proposed as alternative food, little is known about their ecological impacts if released or escaped into natural ecosystems. Further studies should assess the consequences of their establishment in non-native regions.
