Insecticide Resistance Study in Plutella xylostella L. X. The IGR-resistance and the possible management strategy Taiwan Agricultural Research Institute
Cheng, E. Y; C. H. Kao; C. S. Chiu; 鄭允; 高靜華; 邱紀松.
[[abstract]]The benzoylphenyl urea-type insect growth regulators (IGRs) have caused the newest type of resistance in diamondback moth (DBM, Plutella xylos-tella). The possible mechanism, the declining rate, the genetics and the possible management strategy of this resistance have been investigated. The results indicated that DBM can develop IGR-resistance up to thousand folds in less than one and half years or equal to 30 generations in field, and this resistance is attributed to the metabolic degradation by a new mixed function oxidase (mfo) in DBM induced from the intensive IGR sprays. The resistance can only be maintained by continuous IGR selection, or it will decline when the selection pressure was lift. The decline of IGR-resistance can be...
