摘　　要：Wireworm is one of the most important soil pests that damage bamboo shoots,and it is very difficult to control.In order to find the pesticides with high efficiency against bamboo shoot wireworm and low toxicity to the environment,the toxicities of 8 pesticides against wireworm were tested.Results showed that the order of the toxicities to bamboo shoot wireworm of the 8 insecticides from high to low was Fipronil>Phoxime+Carbendazim>Phoxime>Chlorpyrifns>Imidacloprid Ⅱ>Bt>Beauveria bassiana>defatted seed cake of Camellia oleifera.The medium lethal concentration(LC50) of fipronil was 0.014 1 g·kg-1(soil),and fipronil could be used for wireworm control.Wireworm is one of the most important soil pests that damage bamboo shoots, and it is very difficult to control.

Results showed that the order of the toxicities to bamboo shoot wireworm of the 8 insecticides from high to low was Fipronil 〉 Phoxime ＋ Carbendazim 〉 Phoxime 〉 Chlorpyrifns 〉 Imidacloprid Ⅱ〉 Bt 〉 Beauveria bassiana 〉 defatted seed cake of Camellia oleifera. The medium lethal concentration （LC50） of fipronil was 0. 014 1 g·kg^-1（soil）, and fipronil could be used for wireworm control.
