Indoor toxicity and field control efficacy of 13 insecticides to the pest Culcula panterinaria
[Objective]Culcula panterinaria is an omnivorous lepidopteran pest.The study aimed to ef-fectively control C.panterinaria which seriously damages various fruit trees and cash crops in Lin'an city of Zhejiang province.[Method]In this study,the indoor toxicity of 13 insecticides to C.panterinaria egg and three instars of the larva were tested by using the methods of immersion and leaf dipping,respectively.The field experiments were conducted to determine the field control effectiveness of 13 insecticides against the pest.[Result]The results showed that the LC50 of spinetoram,spinosad and chlorantraniliprole to C.pan-terinaria egg were 0.322,0.514 and 0.656 mg/L,respectively.The toxicity of spinosad,chlorantranilip-role and spinetoram to the fifth instar C.panterinaria larvae was higher than other insecticides,and the LC50 were 1.414、2.147 and 2.658 mg/L,respectively.The field control effect of spinosad,chlorantraniliprole and spinetoram on C.panterinaria was higher than that of other insecticides,among which the efficiency of spinosad was 94.56%.[Conclusion]The biologically derived spinosad and spinetoram,which was used in rotation with chlorantraniliprole,were recommended as the insecticides of controlling C.panterinaria.
