摘要:

筛选出防治绿盲蝽(Apolygus lucorum)高效、低毒和安全的杀虫剂,为绿盲蝽的科学防控提供基础数据和科学依据。本研究以食料浸渍法和田间喷雾法,分别测定了噻虫嗪、阿维菌素、苦参碱、鱼藤酮和蛇床子素,5种杀虫剂对绿盲蝽的室内毒力及田间防治效果。室内毒力测定结果显示:5种杀虫剂对绿盲蝽的毒力均随杀虫剂浓度的升高而增强,对绿盲蝽的毒力大小顺序为:噻虫嗪>阿维菌素>苦参碱>鱼藤酮>蛇床子素,田间防治试验结果表明:在绿豆田用药3 d后,300 mg/L噻虫嗪和600 mg/L噻虫嗪的防治效果最好,田间防效均已达到75%以上。在绿豆田用药7 d后,600 mg/L噻虫嗪的防治效果最好,其次为300 mg/L噻虫嗪和1000 mg/L阿维菌素,田间防效均超过70%,1600 mg/L苦参碱田间防治效果为58.94%,1600 mg/L鱼藤酮和1600 mg/L蛇床子素田间防效约为50%。5种杀虫剂对绿盲蝽均有防治效果,噻虫嗪和阿维菌素对绿盲蝽防治效果较好,建议用于绿盲蝽大田防治。

Abstract:

The aim of this research is to select high-efficiency, low-toxicity and safe insecticides for the control of Apolygus lucorum, and to provide basic data and scientific basis for the scientific prevention and control of A. lucorum. The laboratory toxicity and field control effect of different insecticides on A. lucorum were studied. In this study, the laboratory toxicity and field control effect of thiamethoxam, abamectin, matrine, rotenone and osthole on A. lucorum were determined by food dipping method and field spraying method. The results of laboratory toxicity test showed that the toxicity of five insecticides to A. lucorum increased with the increase of insecticide concentration. The order of toxicity to A. lucorum was thiamethoxam > abamectin > matrine > rotenone > osthole. The results of field control test showed that 300 mg/L thiamethoxam and 600 mg/L thiamethoxam had the best control effect after 3 days of application in mung bean field, and the field control effect had reached more than 75%. After 7 days of application in mung bean field, the control effect of 600 mg/L thiamethoxam was the best, followed by 300 mg/L thiamethoxam and 1000 mg/L avermectin, and the field control effect was more than 70%. The field control effect of 1600 mg/L matrine was 58.94%, and the field control effect of 1600 mg/L rotenone and 1600 mg/L osthole was about 50%. It was found that five insecticides had certain field control effects on A. lucorum, among which thiamethoxam and abamectin had better control effect on A. lucorum, and they were recommended to be utilized in the field.
