The family Pteromalidae includes important #parasitoid #wasps, but has become a polyphyletic assembly of genera - a taxonomic revision of this family, using molecular and morphological criteria, has been now published in the Journal of Hymenoptera Research (Dec. 2022, vol. 94, pp. 13-88) by Roger Burks and others - https://doi.org/10.3897/jhr.94.94263

@PeerCommunityIn The article "Non-target effects of ten #essentialoils on the egg #parasitoid #Trichogrammaevanescens" is now published in #openaccess in Peer Community Journal, #zoology section! https://peercommunityjournal.org/articles/10.24072/pcjournal.212/ https://doi.org/10.24072/pcjournal.212

Urban green roof tops can host insect #pests but also a large variety of #parasitoid #wasps - article in Wildlife Research (2022, vol. 49, pp. 659-672) by Aramee C. Diethelm and Susan E. Masta - https://doi.org/10.3389/fevo.2022.983401

One of the ichneumon wasps I think, visiting at New Year, perhaps it came on with the ivy. Wonder what it uses that ovipositor on? #insectodon #wasps #parasitoid

On our window, this afternoon. Possibly an early hatching wasp, emerging from either our potted Christmas tree, or from outside—temperatures have been rather high, as in early Spring. Alas its fate is likely sealed by the absence of flowering plants.

#Advent Day14: #Drosophila hydei was originally a South American #Cactus specialist, but is now a global commensal https://www.sciencedirect.com/science/article/pii/S1055790312001789 and is the UK’s only common repleta-group fly. It has been studied as a host to parasitic mites https://doi.org/10.1017/s0031182016000305 and for a fascinating interaction between #Parasitoid wasps and defensive #Endosymbiont Spiroplasma https://doi.org/10.1371/journal.pone.0012149 . It also briefly held the crown for the longest drosophilid sperm, at around 10 body-lengths https://www.pnas.org/doi/abs/10.1073/pnas.91.20.9277

#Bacterial #endosymbionts often protect their hosts from threats. For instance, #Wolbachia inhibit #viral #pathogens in #insects and #Hamiltonella defensa protect from #parasitoid wasps.

Here, researchers report that #Regiella insecticola protects #aphids from Acyrthosiphon pisum virus. This is only the second #symbiont reported to inhibit viral pathogens in #arthropods.

Success is not enough others must fail: Sperm-limited #parasitoid males continue to mate, which results in lost mating opportunities for their competitors. #science #ecology #animalbehaviour #competition
