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LC_(50)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LC_(50)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。
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,sulf⁃oxaflor,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 LC_(50) of 85.64 mg/L and 404.03 mg/L re⁃spectively at 48 hours after treatment,followed by cyantraniliprole,beta-cypermethrin,deltamethrin,cyhalothrin,azadirachtin.The highest toxicities were detected for thiamethoxam and imidacloprid,with LC_(50) 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,fol⁃lowed by deltamethrin,beta-cypermethrin,cyanidebromide and azadirassin.
