Detecting the presence of target-site resistance to neonicotinoids and pyrethroids in Italian populations of Myzus persicae.

Background: Myzus persicae is a key pest of peach, which in commercial orchards is mainly controlled by chemical treatments. Neonicotinoids represent the main control strategy, but resistance monitoring programmes in Southern Europe have shown the widespread presence of populations highly resistant to this insecticide class in peach orchards. Moreover, in Italy reports of neonicotinoid application failures are increasing.
