花椒棉蚜发生动态、抗药性水平及防治药剂筛选
Occurrence dynamics,insecticide resistance of Aphis gossypii in Zanthoxylum bungeanum field and screening insecticides for control
摘要
Abstract
To clarify the occurrence dynamics,optimal control period,insecticide resistance level of Aphis gossypii in Zanthoxylum bungeanum field and screen control insecticides,the occurrence dynamics of A.gossypii was investigated by diagonal five-point sampling method,the resistance of A.gossypii populations in four counties of Shaanxi province to six common pesticides and optimal control insecticides was tested by indoor bioassay and insecticide screening in field.The results showed that A.gossypii occurred during the growing season of Z.bungeanum,with peak periods occurring in mid-May,early-July or early-August.A.gossypii population in Hancheng city showed resistance to imidacloprid,acetamiprid,chlorpyrifos,lambda-cyhalothrin,bifenthrin and abamectin.On the contrary,A.gossypii population in Qishan county and Feng county showed no resistance to the six pesticides.Flonicamid,spirotetramat and avermectin had better indoor toxicity effects.Flonicamid 50%water dispersible granules(WG)showed rapid efficiency and good persistence in field.The crucial period for controlling A.gossypii in Z.bungeanum field was from late-April to early-May,and it was suggested that applying flonicamid,thiamethoxam or spirotetramat to control A.gossypii.关键词
