Evidence For Organelle-Like Extracellular Vesicles From A Parasite Of Drosophila And Their Function In Suppressing Host Immunity, Mary Heavner
Dissertations, Theses, and Capstone Projects
Parasitic wasps act as keystone species in natural ecosystems. Adept at suppressing immunity of their insect hosts, these natural enemies of insect pests are used for biocontrol in many parts of the world. Female parasitic wasps of the closely-related species Leptopilina heterotoma (Lh), a generalist of many Drosophilia flies, and Leptopilina boulardi (Lb), a specialist on flies of the melanogaster subgroup, produce venom and virus-like particles (VLPs) in their long gland-reservoir complexes, a secretory organ connected to ovipositors. Venom and VLPs are deposited, along with wasp eggs, into the body of the wasp’s larval fly host …
