Intentional introductions of the egg parasitoid Trissolcus japonicus (Ashmead) (Hymenoptera: Scelionidae) have been carried out in Italy since 2020 for the control of the invasive Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), with releases conducted along ecological corridors of untreated vegetation. These introductions took place in an area where unintentionally introduced populations of Trissolcus mitsukurii (Ashmead)...

The European stag beetle, Lucanus cervus , is a flagship saproxylic species in Europe, listed in Annex II of the Habitats Directive and threatened by habitat loss and fragmentation. This study documents the first recorded arboreal predation of adult L. cervus by the edible dormouse, Glis glis , based on three years of field observations in northern Italy. Predation occurred mainly in the canopy shortly after sunset, coinciding...

Within the scope of integrated management of brown marmorated stink bug, Halyomorpha halys , the compatibility of symbiotic control with other strategies must be evaluated to promote biodiversity conservation. This study aimed to assess the impact of antimicrobial substances, useful in symbiotic control of H. halys , on the egg parasitoid Trissolcus japonicus through the treatment of egg masses with fungicides (copper hydroxid...

The highly destructive Asian brown marmorated stink bug ( Halyomorpha halys, BMSB) invaded Europe, Caucasus region, and North and South America. Efforts to control it are ongoing in the Palearctic European-Mediterranean Basin and North America by introducing and redistributing two Asian stenophagous scelionid egg parasitoids ( Trissolcus japonicus and T. mitsukurii ) that are attacked by an adventive oligophagous pteromalid As...

The future of the native European crayfish Austropotamobius pallipes depends on accurate conservation management. The goal of this paper is to attempt an investigation of the major ethical conflicts that can emerge in the conservation of this endangered crayfish threatened by invasive competitors, introduced diseases, and landscape alteration. To assess this issue, we will employ the Ethical Matrix, in a version explicitly tai...
