采用茎叶喷雾法测试了6种杀虫剂对红花指管蚜的防效。结果表明,药后1 d,1.8%阿维菌素EC 500、1 000倍液、25%吡虫啉WP 500倍液、3%啶虫脒EC 1 000倍液、5.7%氟氯氰菊酯EC 1 000倍液及3%阿啶达EC 2 000倍液的处理防效较高,均在70%以上;药后3d各处理防效均明显提高,吡虫啉500倍液处理防效达92.28%;药后7 d,除阿维菌素和阿啶达处理外,其他处理的防效均呈现不同程度的下降。试验中对天敌杀伤力较小的是螺虫乙酯、阿维菌素和吡虫啉。从总体防效、保护生态等方面综合考虑,推荐阿维菌素和吡虫啉作为替代药剂防治红花指管蚜。
The effect of 6 kinds of insecticides on the control of Aphis gossypii Hook. The results showed that 1.8% avermectin EC 500,1000 times, 25% imidacloprid WP 500 times, 1% acetamiprid EC 1 000 times, 5.7% cyfluthrin EC 1 000 times And 3% Aldeparin EC 2 000 times higher control effect, were more than 70%; 3d control effect was significantly improved after treatment, imidacloprid 500 times control effect reached 92.28%; after 7 d , In addition to avermectin and aldehyde treatment, the other treatment showed varying degrees of control effect. Less lethal to natural enemy in the test is spirotetramat, avermectin and imidacloprid. From the overall control efficiency, ecological protection and other aspects of comprehensive consideration, recommended avermectin and imidacloprid as an alternative to control safflower aphid.
