Validation of a Field Monitoring System for BPU-Type IGR Resistance in the Diamondback Moth, Plutella xylostella Presumed Working Scheme Based on IRAC Method No.7 (Leaf Dipping Method)

Abstract

Results of the IRAC Method NO.7 (leaf dipping method) were compared to those of the spray tower method in aspect of the resistance of diamondback moth (DBM), Plutella xylostella, to benzoylphenyl urea (BPU)-type insect growth regulators (IGR). The leaf dipping method resulted in 3.29-fold higher BPU-IGR deposit than the spray tower method. 本研究係比較IRAC(Insecticide Resistance Action Committee)之建議方法，IRAC Method No. 7（葉片浸藥扶），與噴霧塔兩種方法測試小菜蛾對BPU類生長調節劑抗藥性之差異。葉片之沾藥量方面，葉片浸藥怯高出噴霧塔法3.29倍。
