摘　　要：【目的】筛选防治橘小实蝇的应急防控药剂,并探讨如何合理用药。【方法】采用药膜法测定了7种杀虫剂对郑州地区橘小实蝇成虫的触杀毒力,同时评估了郑州地区橘小实蝇田间种群对7种药剂的抗性水平。【结果】各供试药剂对郑州地区橘小实蝇种群的毒力大小依次为溴氰菊酯>阿维菌素>高效氯氰菊酯>噻虫胺>氰戊菊酯>啶虫脒>吡虫啉。田间种群抗性对比结果显示,郑州地区橘小实蝇种群对吡虫啉的抗性已达到极高抗水平,对高效氯氰菊酯、噻虫胺、啶虫脒的抗性达到中抗水平,对氰戊菊酯的抗性达到低抗水平,对溴氰菊酯和阿维菌素尚处于敏感水平。【结论】明确了7种杀虫剂对郑州地区橘小实蝇的毒力效果和种群抗性水平,建议防控时首选溴氰菊酯和阿维菌素。【Objective】 In order to screen out the emergency control agents for controlling Bactrocera dorsalis and guide the rational use of pesticides.【Method】The toxicities of seven insecticides to B.dorsalis adults in Zhengzhou Area were determined by residue film method,and the resistance level of the Zhengzhou population of B.dorsalis adults to seven insecticides was evaluated.【Result】The results showed that the toxicities of the tested insecticides to the Zhengzhou population of B.dorsalis adults from high to low were as follows:deltamethrin,abamectin,beta-cypermethrin,clothianidin,fenvalerate,abamectin and imidacloprid.The field population resistance comparison results demonstrated that the Zhengzhou population resistance of B.dorsalis adults had a very high level to Imidacloprid,a moderate level to Beta-cypermethrin,clothianidin and acetamiprid,and a low level to fenvalerate.It was still susceptible to deltamethrin and abamectin.【Conclusion】 This study confirmed the virulence effects and population resistance levels of seven insecticides to B.dorsalis in Zhengzhou Area,and suggested that deltamethrin and abamectin were priority recommended insecticides for the control of B.dorsalis.
