摘要
通过室内抗性品系选育,研究了柑橘全爪螨对甲氰菊酯和阿维菌素的抗性发展情况,并就其与柑橘园常用11种杀螨剂的交互抗性进行了分析。结果表明:在柑橘全爪螨19代中用甲氰菊酯和阿维菌素分别不连续汰选16次和11次后,柑橘全爪螨对两者的抗性分别为29.92和3.80倍;甲氰菊酯抗性品系(FeR)对哒螨灵、三氯杀螨醇和三唑锡产生了明显的交互抗性,阿维菌素抗性品系(AbR)对甲维盐产生了明显的交互抗性。试验结果可为柑橘全爪螨抗性治理提供参考。
On the basis of resistance breeding and selection in laboratory,the resistance development of Panonych-us citri to fenpropathrin and abamectin was investigated and the cross-resistance of FeR and AbR to 1 1 acaricides was also studied.The results showed that,after 11-and 16-times of selection with abamectin and fenpropathrin,the re-sistance of P .citri to the two acaricides increased by 3.80-and 29.92-fold,respectively.Bioassay revealed that the cross-resistance of FeR to pyridaben,dicofol,azocyclotin and the cross-resistance of AbR to emamectin benzoate were very significant.The results provided references for the resistance management of P .citri to acaricides.
