摘　　要：用溴氰菊酯、久效磷、灭多威及硫丹对敏感棉蚜以浸渍法连续选择１６代或１２代后，棉蚜对上述４种药剂的敏感度分别降低了３００．０、６．０、５．０、及５．０倍。对４个抗性品系和敏感品系棉蚜的实验种群生命表分析表明：溴氰菊酯抗性品系棉蚜的存活率呈“Ｓ”形曲线下降，其内禀增长率为０．２９８５；久效磷抗性品系及敏感品系棉蚜的存活率呈二次曲线下降趋势，其内禀增长率分别为０．２９７９和０．２９７３；灭多威及硫丹抗性品系棉蚜的存活率呈指数曲线下降趋势，其内禀增长率分别为０．２６０２和０．２５３３。A susceptible strain of the cotton aphid was selected for resistance with deltamethrin monocrotophos, methomyl and endosulfan by immersion method generation to generation. Up to the 16th generation the susceptibility of the strain selected with deltamethrin was decreased by 300fold, Up to the 12th generation the susceptibility of the strain selected with monocrotophos, methomyl and endosulfan was decreased by 6.0,5.0 and 5.0fold respectively. In the laboratory, the life table statistics of four resistant strains and one susceptible strain showed that the survival of Rdeltamethrin strain declined in coincidence with asshaped curve and the intrinsic natural increase (γm) of this resistant strain was 0.2985. The survival ship of Rmonocrotophos and the susceptiple strains may be expressed by a quadratic curve and the γm of these two resistant strain were 0.2979 and 0.2973 respectively. The survival of Rmethomyl and Rendosulfan strains declined in coincidence with an exponential decay curve and the γm of these two resistant strains were 0.2602 and 0.2533 respectively.
