Laboratory studies were conducted to evaluate the insecticidal effect of diatomaceous earth (DE) against adults of Prostephanus truncatus (Horn) (Coleoptera: Bostrychidae) in maize. Four concentrations of diatomaceous earth (0, 1000, 2000, and 3000 ppm; n = 9) were tested, and adult mortality was assessed after 3, 7, 14, and 21 days of exposure. After the final mortality counts, dead and live parental adults were removed and p...

The present study investigated the application of elevated and low temperatures as an alternative strategy for managing insect pests in stored Corinthian currants ( Vitis vinifera L., var. Apyrena). The efficacy of both high- and low-temperature exposure was evaluated against two key storage pests, Plodia interpunctella (Lepidoptera: Pyralidae) and Oryzaephilus surinamensis (Coleoptera: Silvanidae), under commercial storage co...

The use of inert materials have been proposed as viable alternatives of traditional neurotoxic insecticides and fumigants. In this work, we examined the insecticidal effect of attapulgite, applied alone or in combination with oregano essential oil, for the control of adults of the granary weevil, Sitophilus granarius (L.) (Coleoptera: Curculionidae), on three different grains, i.e. wheat, rice and barley, and at two temperatur...

The aim of this work was to investigate the population growth of Lasioderma serricorne (F.) with two populations with different susceptibility to phosphine (one resistant and one susceptible). Population growth was recorded on different days (35 days, 50 days, 65 days, 80 days, 95 days, and 110 days) in two different commodities: (a) mixed food consisted of wheat flour (10 parts) + cornmeal (10 parts) + brewers’ yeast (1.5 par...

Mosquitoes are a threat worldwide since they are vectors of important pathogens and parasites such as malaria, dengue, yellow fever, and West Nile. The residual toxicity of several commercial mosquito larvicides was evaluated for the control of Culex pipiens pipiens under controlled laboratory and semi-field conditions during late spring and summer of 2013. The evaluation included six different active ingredient formulations,...

In the present study we examined the effect of the presence of wheat bugs ( Eurygaster spp. and Aelia spp.) on wheat on the mortality, progeny production and infestation patterns of three stored product insects, Trogoderma granarium Everts, Sitophilus oryzae (L.) and Rhyzopertha dominica (F.). The bioassays were carried out under laboratory conditions (25 ± 1 °C, 60 ± 5% relative humidity (r.h.) and continuous darkness), and 2...
