Diagnosis of Resistance to Organophosphorus Insecticides in Myzus persicae (Sulz.)

摘要: THE chemical control of the green peach aphid Myzus persicae (Sulz.), which damages many crops both directly and by transmitting numerous virus diseases, is seriously jeopardized world wide occurrence resistance to organophosphorus insecticides. In United Kingdom previously confined glasshouse now occurs in field. Nothing known about nature mechanism(s) these insects little patterns resistance. We wish report (1) large differences activity ali-esterases susceptible resistant aphids can be used determine even single aphids, (2) some properties enzymes between house flies, (3) a marked decrease or increase when are treated with insecticides presence ‘Sesamex’ (2-(3,4-methylene-dioxyphenyl)3,6,9-trioxaundecane). This evidence that multi-function oxidases involved aphids.
