BACKGROUND: Myzus persicae is a serious pest that attacks a broad range of agricultural crops. This species has developed chemical resistance to many insecticides globally, and within Australia resistance to multiple chemical groups has been identified. Resistance to neonicotinoid insecticides has been discovered in several countries, but has not previously been confirmed in Australia. We use biomolecular assays and bioassays on field-collected populations to investigate neonicotinoid resistance in M. persicae within Australia. RESULTS: Several geographically and genetically distinct populations showed evidence for resistance in bioassays. Genetic markers identified that the mechanism of neo..View full abstract
