| 摘 要： | 在实验室抗性选育的基础上,应用数量遗传学中的域性状分析法,研究了桔全爪螨北碚种群对阿维菌素和甲氰菊酯2种杀螨剂的抗性现实遗传力,并对2种药剂在不同杀死率下抗性发展的速率进行了预测.结果表明:用阿维菌素和甲氰菊酯分别不连续汰选11及16代后,桔全爪螨对两者的抗性分别为3.8和29.9倍,抗性现实遗传力分别为0.0475和0.1544.在室内选择条件下,杀死率为50%～90%时,要获得10倍抗性,甲氰菊酯仅需要7～16代,阿维菌素则需要12～26代.而在田间选择情况下,2种药剂都将需要更长的时间.抗性筛选结果表明,生物源农药阿维菌素的抗性风险明显低于菊酯类农药甲氰菊酯.试验结果可为桔全爪螨抗性治理提供参考.

| Abstract: | On the basis of resistance breeding and selection in laboratory,and by using the threshold trait analysis in quantitative genetics,this paper studied the realized resistance heritability of Panonychus citri(McGregor) collected from Beibei of Chongqing to avermectin and fenpropathrin,and predicted the resistance risk of P.citri to these two acaricides.After 11-and 16-generations of selection with avermectin and fenpropathrin,the resistance of P.citri to the two acaricides increased by 3.8-and 29.9-fold,and t... |
