4种杀虫剂对大豆蚜虫的室内毒力测定

Toxicity Determination of Four Insecticides on Aphis glycines Matsumura

为明确啶虫脒、吡虫啉、烯啶虫胺和吡蚜酮等杀虫剂对大豆蚜虫的毒力和防治效果,采用浸渍法进行了4种杀虫剂对大豆蚜虫的室内毒力测定。结果表明,4种杀虫剂对大豆蚜虫都有较高的毒力,以啶虫脒对大豆蚜虫的毒力最高,LC50为7.026μg/g,其余3种杀虫剂的毒力大小依次为吡虫啉、烯啶虫胺、吡蚜酮,LC50分别为9.484、15.247和43.734μg/g,对大豆蚜虫均有较好的防治效果。

In order to explicit the control effects of acetamiprid, imidacloprid, nitenpyram metrozine on Aphis glycines Matsumura, indoor toxicity determination was carried out using dipping The results showed that the toxicity of acetamiprid was the strongest with the LCso of 7. 026μg/g, was imidacloprid, nitenpyram and pymetrozine in order with the LCso of 9. 484, 15. 247 and 43. 734 spectively. All of them had better control effects on Aphis glycines. and py- method. and thenμg/g re-
