Captures of MFO-resistant Cydia pomonella adults as affected by lure, crop management system and flight

The main resistance mechanism of codling moth (Cydia pomonella) in the tree fruit area of Lleida (NE Spain) is multifunction oxidases (MFO). We studied the frequency of MFOresistant adults captured by different lures, with and without pear ester, and flights in orchards under different crop manageme...
