Monitoring for organophosphate and carbamate resistance was carried out on five major insect pests of cotton collected from 22 cotton-growing districts across India. Resistance was monitored in Helicoverpa armigera (Hübner) and Pectinophora gossypiella (Saunders) for the period 1995-1999 and for Spodoptera litura (Fabricius), Earias vittella (Fabricius) and Bemisia tabaci (Gennadius) in a survey conducted during the 1997-98 cropping season. Of the 53 field strains of H. armigera, only four were found to exhibit resistance to quinalphos, the highest 15-fold, whereas all 16 field strains tested were found to be resistant to monocrotophos. Similarly, out of 40 field strains tested, only eight were found to express appreciable resistance to methomyl. Resistance in P. gossypiella to quinalphos was high in the majority of the strains tested. Of the seven strains of E. vittella tested, two strains from northern India exhibited > 70-fold resistance to monocrotophos. Of the 11 S. litura strains tested, only four were found to exhibit resistance factors of 10 to 30-fold to quinalphos and monocrotophos. All of the B. tabaci field strains exhibited resistance to methomyl and monocrotophos and susceptibility to triazophos. Practical implications for pest control resulting from the observed patterns of cross-resistance between quinalphos, monocrotophos and methomyl are discussed.
对从印度22个棉花种植区采集的5种主要棉花害虫进行了有机磷和氨基甲酸酯抗性监测。在1995 - 1999年期间对棉铃虫（Helicoverpa armigera (Hübner)）和棉红铃虫（Pectinophora gossypiella (Saunders)）进行了抗性监测，在1997 - 1998种植季的一项调查中对斜纹夜蛾（Spodoptera litura (Fabricius)）、红铃虫（Earias vittella (Fabricius)）和烟粉虱（Bemisia tabaci (Gennadius)）进行了监测。在53个棉铃虫田间品系中，仅发现4个对喹硫磷有抗性，最高达15倍，而所有测试的16个田间品系均对久效磷有抗性。同样，在测试的40个田间品系中，仅发现8个对灭多威有明显抗性。在大多数测试的棉红铃虫品系中，对喹硫磷的抗性较高。在测试的7个红铃虫品系中，来自印度北部的2个品系对久效磷表现出>70倍的抗性。在测试的11个斜纹夜蛾品系中，仅发现4个对喹硫磷和久效磷表现出10至30倍的抗性因子。所有烟粉虱田间品系均对灭多威和久效磷有抗性，对三唑磷敏感。讨论了喹硫磷、久效磷和灭多威之间观察到的交叉抗性模式对害虫防治的实际影响。
