摘要: 采用喷雾法测定了9种常用化学杀虫剂和5种生物源杀虫剂对蠋蝽(Arma chinensis Fallou)的室内毒力,并在大豆和辣椒上评价了溴氰菊酯、高效氯氰菊酯、吡虫啉、溴氰虫酰胺、印楝素5种杀虫剂对蠋蝽的安全性。结果表明,供试14种杀虫剂中,氟啶虫胺腈、氯虫苯甲酰胺、苏云金杆菌(Bacillus thuringiensis)、短稳杆菌(Empedobacter brevis)及草地贪夜蛾核型多角体病毒(Spodoptera frugiperda NPV)对蠋蝽的室内毒力最低,对蠋蝽安全;茚虫威和苦参碱的毒力相对较低,其48 h时的LC50分别为85.64 mg/L和404.03 mg/L,其次为溴氰虫酰胺、高效氯氰菊酯、溴氰菊酯、高效氯氟氰菊酯、印楝素;噻虫嗪和吡虫啉的室内毒力最高,其48 h时的LC50分别为0.96 mg/L和1.16 mg/L。安全性测试的5种杀虫剂对蠋蝽均存在安全性风险,其中,吡虫啉的风险最高,24 h后的死亡率均达100%,其次依次为溴氰菊酯、高效氯氰菊酯、溴氰虫酰胺、印楝素。

Abstract: The indoor toxicity of 9 common-used insecticides and 5 biological insecticides to Arma chinensis was assessed by spray method. The safety assessment of five pesticides (deltamethrin, beta-cypermethrin, imidacloprid, cyantraniliprole, azadirachtin) to Arma chinensis on bean and pepper plant were also tested in the field. The results showed that, among the 14 tested insecticides, sulfoxaflor, chlorantraniliprole, Bacillus thuringiensis, Empedobacter brevis and Spodoptera frugiperda NPV all showed least toxicity and were relative safe to Arma chinensis; Indoxacarb and matrine were both lower toxicities with LC50 of 85.64 mg/L and 404.03 mg/L respectively at 48 hours after treatment, followed by cyantraniliprole, beta-cypermethrin, deltamethrin, cyhalothrin, azadirachtin. The highest toxicities were detected for thiamethoxam and imidacloprid, with LC50 of 0.96 mg/L and 1.16 mg/L respectively at 48 hours after treatment. Among the five insecticides tested, imidacloprid had the highest risk of Arma chinensis, with 100% mortality after 24 h, followed by deltamethrin, beta-cypermethrin, cyanidebromide and azadirassin.
