Novel but stable endosymbionts have contrasting effects on aphid dispersal and plant feeding damage in the cereal pest Diuraphis noxia

Xinyue Gu, Alexander O. Gill, Qiong Yang…·Ary A. Hoffman

This study shows that introducing novel endosymbionts into the aphid Diuraphis noxia alters its dispersal ability and plant feeding damage, with Rickettsiella increasing damage and Regiella reducing it.

Revisiting the diversity of secondary endosymbionts in the major pest oat aphid, Rhopalosiphum padi

Qiong Yang, Bin Zhu, Wenjuan Yu…·Ary A. Hoffmann

This study investigates the presence of secondary endosymbionts in Rhopalosiphum padi, finding limited diversity beyond Hamiltonella defensa and highlighting potential technical and ecological factors affecting detection.
