Parasitic wasp‐associated polydnavirus and venom affect arthropod community assembly on wild cabbage via the caterpillar host EcolEntomol

Matrougui, @rosinasavisaar.bsky.social @ideevl.bsky.social et al. show that the most produced polydnavirus circles are those that integrate at the highest efficiency in host genomes, even when controlling for the quantity of circles.

Matrougui @ideevl.bsky.social et al. explore footprints of polydnavirus integration in insect genomes to study the host range of parasitoid wasps, revealing that PDV-mediated HGT affects a wider range of insects than previously thought.

New PapeR: Symbiotic polydnavirus and venom reveal parasitoid to its hyperparasitoids In: PNAS http://hdl.handle.net/20.500.11755/3dacb4dd-bc7b-4245-9dde-d6758aafdfa3

Wow. Wasp parasitoid of spruce budworm simultaneously injects immune-suppressing polydnavirus into host with egg #IALE2015

I love parasites and endosymbionts, my favorite is probably M paradoxa and the wasp/polydnavirus connection. Oh also Sputnik. I love seeing layers of parasites and symbionts combining so thoroughly it's hard to tell which is which.

These wasps, Cotesia congregata, are fucking metal. They manufacture polydnavirus virions that they inject into the caterpillar along with venom and eggs that hijack the caterpillar's cells.
