The results showed that : to KQR strain p p g of Helicover a armi era which resistant to rethroids , the s ner ism was marked or si nifi p g py y g g cant , While to the susce tible strain ( HDS) , the s ner ism was rather weak. The effects of p y g s ner ist was connected with the resistant level and main mechanisms of Helicover a y g p armi era . Biochemical stud su ested that : the s ner ism of PBO and SV1 was ot b in g y gg y g g y hibiting directly the monooxygenase activity of MFO. Ke words : Helicover a armi era S ner ist S ner ism MFO
