- 摘要:
- 以香蕉球茎象甲为试虫，采用浸香蕉球茎接虫法和点滴法，研究了6种药剂对其成虫的毒力和室内药效。结果表明：6种药剂对香蕉球茎象甲成虫的毒力依次为高效氯氟氰菊酯>异丙威>敌百虫>吡虫啉>啶虫脒>阿维菌素，24 h的LC50值分别为22.847 2、45.460 1、110.695 7、158.669 7、192.486 1、218.659 3 mg/L；室内药效结果表明，药后14 d，除敌百虫外，高效氯氟氰菊酯、异丙威、吡虫啉、啶虫脒和阿维菌素对香蕉球茎象甲成虫的校正死亡率均达到100%，且高效氯氟氰菊酯和异丙威的速效性好，而吡虫啉、啶虫脒和阿维菌素的药效持续期长。高效氯氟氰菊酯、异丙威、吡虫啉、啶虫脒和阿维菌素均可作为田间防治香蕉球茎象甲的潜力药剂。
- Abstract:
- Taking Cosmopolites sordidus as test insect，the indoor toxicity and efficacy of six insecticides to the adults of C.sordidus were tested by corm-dipping method and topical application method respectively.The results showed that the toxicity of six insecticides to C.sordidus adults from the highest to the lowest could be arranged by：lambda-cyhalothrin>isoprocarb>trichlorphon>imidacloprid>acetamiprid>abamectin，and the LC50 values of 24 h were 22.847 2，45.460 1，110.695 7，158.669 7，192.486 1，218.659 3 mg/L，respectively.The indoor efficacy trials showed that the corrected mortality of all the tested insecticides but trichlorphon on C.sordidus adults reached 100% in the 14 days after treatment.Moreover，lambda-cyhalothrin and isoprocarb had better instant effect，and imidacloprid，acetamiprid and abamectin had longer persistence.Lambda-cyhalothrin，isoprocarb，imidacloprid，acetamiprid and abamectin could be used as potential insecticides to control C.sordidus in field.
