摘  要：
以5种杀虫剂为供试药剂,以韭菜迟眼蕈蚊为供试虫源,采用定量滴加法,在8、16、24℃条件下测定了5种药剂对韭菜迟眼蕈蚊幼虫毒力的温度效应,并进行了盆栽和田间的药效试验。结果表明:5种药剂均表现为正温度效应,其中吡虫啉的正温度效应最明显,24℃时的毒力是8℃时的4.66倍;其次为辛硫磷、噻虫胺和噻虫嗪,三者温度效应基本一致;而甲维盐温度效应最小;盆栽药效试验结果表明,在50mg/L的处理剂量下,噻虫胺处理的幼虫校正死亡率为75.2%,防效最高,分别比同剂量处理的辛硫磷、吡虫啉和噻虫嗪处理高14.5%、24.8%和28.2%;田间药效试验表明,噻虫胺以100mg/L和50mg/L灌根处理最好,处理25d后的防效达100%和95.2%,显著优于200mg/L辛硫磷的防效(84.2%);吡虫啉100mg/L、噻虫嗪100mg/L的处理,防效分别达93.7%和96.9%,均优于辛硫磷200mg/L和100mg/L的处理;3种新烟碱类杀虫剂对韭蛆防效高,其中以噻虫胺表现优异,对韭菜迟眼蕈蚊的幼虫持续控制作用大,环境友好,十分适合田间防治韭蛆推广应用。

摘  要：
Taking 5kinds of pesticide as test drug and Bradysia odoriphagaas test pest,the effect of temperature on toxicity of seclected insecticides on Bradysia odoriphagawas evaluated,the toxicities of 5insecticides in 8、16、24℃ were studied with dripping ration liquid method,and their control efficiency in the field were also studied.The results showed that the toxicities of 5insecticides showed positive temperature effect.Among these insecticides,Imidacloprid showed the most obvious positive temperature effect,toxicity of Imidacloprid in 24℃ was 4.66times higher than that in 8℃. Methomyl,Clothianidin and Thiamethoxam's positive temperature effect were similar,and the positive temperature effect of Emamectin benzoate was minimum.In pot test,Emendation larvae mortality was 75.2% when roots were irrigated by Clothianidin 50 mg/L,which was 14.5%,24.8% and 28.2% higher than the same dose treatment of Methomyl, Imidacloprid and Thiamethoxam respectively.In field test,Clothianidin 100 mg/L and 50mg/L irrigating roots treatments were the best when processed 25days.The pesticide effect of Clothianidin were 100% and 95.2% while control efficiency of Methomyl 200mg/L was 84.2%.Pesticide effect of Imidacloprid and Thiamethoxam 100mg/L irrigating roots were 93.7%and 96.9%respectively,which were also better than Methomyl 200mg/L and 100mg/L. The 3kinds of neonicotinoids all had good pesticide effect on Bradysia odoriphaga.Among them,Clothianidin was outstanding and had a persistent control function on Bradysia odoriphaga.It was environment friendly and very suitable for the application in the fields.
