Insecticide resistance mechanisms and their management in Helicoverpa armigera (Hubner): a review  [2007]

Ahmad, M. (TS & D Leaders, 143-A, Industrial State, Multan (Pakistan));

استعراض النص الكامل

The development of insecticide resistance management strategies requires a comprehensive knowledge of mechanisms by which insects evolve insecticide resistance. Helicoverpa armigera has evolved resistance to almost all chemical groups directed towards it worldwide including organophosphates, carbamates, and pyrethroids. The judicious use of chemicals can greatly help to preserve the usable life span of insecticides. This requires knowledge of mechanisms of resistance, which can prevent un-necessary use of pesticides to which insects had already evolved or can evolve resistance. The literature review on insecticide resistance, mechanisms and resistance management will help design robust and effective control strategies against H. armigera. This purpose gives such a review.
