| 摘 要： | 应用FAO推荐的微量毛细管点滴法，测定了棉蚜对六种常用杀虫剂的LD50，并与敏感蚜比较。得出抗药性倍数。棉蚜对有机磷杀虫剂的抗药性，增加缓慢，从1960年至今增加了500～700倍。而对于拟菊酯类杀虫剂的抗性增加较快，仅3～4年就达到667。7～9937．4倍。每年增加1.5～2倍。本项研究还应用棉蚜的防治指标和综合治理措施，对抗性棉蚜进行了治理抗性的试验研究。

| Abstract: | Studies on mornitoring and management of the resistance to determine the toxicity of six kinds of commonly used insecticide with the aim at comparing susceptibility between the aphids and obtaining the resistance index. The resistance of cotton aphids to organophosphorus compounds has. been increesing slowly, being up 500-700 times since 1960s, whereas the resistance to pyrethroids has been strikingly high (667.7-9937.47R. S.) with 1.5-2 old increase each year.Resistance experiments have been done for three vears. Experiment results and economic benefit have been described in the paper. |
