Bacillus thuringiensis kurstaki (Btk) is among the most used microbial agent worldwide to control lepidopteran pests in organic and non-organic crops. The extensive use of this bioinsecticide and its environmental accumulation may become a major issue for integrated pest management (IPM) programs that include Btk and non-target species...

Endoparasitoid wasps are essential regulators of insect pests in ecosystems as well as important biological control auxiliaries. Traits important for parasitism success, such as the injection of venom proteins at oviposition, have thus been mainly studied. However, identification of the key genes involved among the large number of genes...

Recent studies suggest that the pea aphid (Acyrthosiphon pisum) has low immune defenses. However, its immune components are largely undescribed, and notably, extensive characterization of circulating cells has been missing. Here, we report characterization of five cell categories in hemolymph of adults of the LL01 pea aphid clone, devoid of...

Parasitoid wasps rely primarily on venom to suppress the immune response and regulate the physiology of their host. Intraspecific variability of venom protein composition has been documented in some species, but its evolutionary potential is poorly understood. We performed an experimental evolution initiated with crosses of two lines of...
