摘要: Amsacta albistriga is one of the important pests oilseed crops in India. This pest has developed high resistance to organophosphate (OP) insecticide field. Therefore, cypermethrin was used as an alternative for this pest. After 20 generations selection with cypermethrin, LD50 value A. albistriga increased by 21.5-folds. The synergism ratio piperonyl butoxide (PBO) and triphenyl phosphate (TPP) 10- 9.6-fold resistant strains comparatively, 3.9 4.2-fold susceptible strains. Detoxification enzyme analysis native PAGE electrophoresis esterase isoenzyme further revealed that mixed function oxidase may be involved CypRes strain. In addition overexpression CYP4M44, CYP9A77 CYP6B47 (ortholog) can confer metabolic These data provide a foundation study mechanism observed A. albistriga.
