【摘要】 为了利用棉蚜抗性种群的适合度代价,指导田间棉蚜种群抗药性治理,笔者采用浸渍法测定并明确了河北省不同地区棉蚜对6种杀虫剂的抗性水平及差异,并组建了河北省不同地区棉蚜的实验种群生命表,以期明确河北省抗性棉蚜种群的适合度变化。结果表明,邯郸棉蚜种群对丁硫克百威(RI=80.5)、氰戊菊酯(RI=28.6)和阿维菌素(RI=108.7)的抗性明显高于保定和沧州地区棉蚜种群。从各地区棉蚜实验种群生命表结果来看,邯郸棉蚜种群净繁殖率(37.9±2.51)和相对适合度(0.78)明显低于室内敏感种群,而保定和沧州棉蚜均与敏感种群没有显著性差异。结合已有棉蚜抗性种群适合度研究结果,笔者认为河北省邯郸棉蚜种群适合度下降可能与其对丁硫克百威或阿维菌素的高抗性有关。因而,针对邯郸棉蚜种群抗药性治理,应暂停使用丁硫克百威和阿维菌素,轮换使用抗性风险较低的吡虫啉、噻虫胺等杀虫剂品种。

【Abstract】 In order to exploit the fitness cost and direct the management of the resistant population of Aphis gossypii Glover in the field, the resistance level of A.gossypii from different areas in Hebei province to six insecticides were determined by dipping method. The population fitness was also studied according to the established life table of the experimental population of A.gossypii. The results showed that the resistance of Handan population to carbosulfan(RI=80.5), fenvalerate(RI=28.6) and abamectin(RI=108.7) were significantly higher than that of Baoding and Cangzhou populations. Based on the life tables of the experimental populations of A.gossypii from different areas, the net growth rate(37.9±2.51) and relative fitness(0.78) of the Handan population were significantly lower than that of the indoor sensitive population, but there was no significant difference between the susceptible population and Baoding, Cangzhou populations. Our studies suggested that the decline in the fitness of Handan population could be related to its high resistance to carbosulfan or abamectin. Therefore, the use of carbosulfan and abamectin should be suspended, and the use of imidacloprid and clothianidin is recommended for the management of A.gossypii in Handan.
