The need for an integrated strategy to control blue-green aphids has been heightened by the discovery of new pesticide-resistant populations in lentil crops in Victoria’s Wimmera and Mallee regions. Recent research led by Dr Evatt Chirgwin (Cesar Australia) found new resistant populations in these important pulse-growing regions after previous testing showed no resistance there – indicating this is a recent development.

Abstract The bird cherry-oat aphid, Rhopalosiphum padi, is a major pest of agriculture due to its ability to directly damage crops and transmit plant viruses. As industries move away from chemical pest control, there is interest in exploring new options to suppress the impact of this pest. Here we describe the production of a transinfected line of R. padi carrying the bacterial endosymbiont, Regiella insecticola, originating from the green peach aphid, Myzus persicae.
