Transcriptomic responses of the aphid Myzus persicae nicotianae Blackman (Hemiptera: Aphididae) to insecticides: Analyses in the single Chilean clone of the tobacco aphid

The tobacco aphid Myzus persicae nicotianae Blackman is a subspecies of the highly polyphagous and agricultural pest Myzus persicae (Sulzer). For its control, insecticide applications are widely used, but resistance to numerous molecules has been reported, displaying at least three insecticide resis...
