The Drosophila endoparasitoid wasps Leptopilina boulardi and L. heterotoma (Hymenoptera: Cynipidae) are proovigenic species, i.e., females contain their lifetime number of mature eggs at emergence. They are therefore able to immediately parasitize many hosts when present. In response to parasitoid oviposition, the larval host D. melanogaster...

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...

In healthy Drosophila melanogaster larvae, plasmatocytes and crystal cells account for 95% and 5% of the hemocytes, respectively. A third type of hemocytes, lamellocytes, are rare, but their number increases after oviposition by parasitoid wasps. The lamellocytes form successive layers around the parasitoid egg, leading to its encapsulation and...

Aspartylglucosaminidase (AGA) is a low-abundance intracellular enzyme that plays a keyrole in the last stage of glycoproteins degradation, and whose deficiency leads to humanaspartylglucosaminuria, a lysosomal storage disease. Surprisingly, high amounts of AGAlikeproteins are secreted in the venom of two phylogenetically distant hymenopteran...

The pea aphid Acyrthosiphon pisum hosts different facultative symbionts (FS) which provide it with various benefits, such as tolerance to heat or protection against natural enemies (e.g. fungi, parasitoid wasps). Here, we investigated whether and how the presence of certain FS could affect phenoloxidase activity, a key component of insect...

Endoparasitoid wasps, which lay eggs inside the bodies of other insects, use various strategies to protect their offspring from the host immune response. The hymenopteran species of the genus Leptopilina, parasites of Drosophila, rely on the injection of a venom which contains proteins and peculiar vesicles (hereafter venosomes). We show here...
