Abstract:The field efficacy of five systemic insecticides against Fenusella taianensis larvae was studied by using the field investigation and analysis method.The results showed that all five insecticides had certain efficacy on Fenusella taianensis larvae.One day after treatment,the corrected efficacy of 50%dinotefuran SG 2000 times liquid was 70.24%,while the corrected efficacy of 20%chlorantraniliprole SC 8000 times liquid was only 3.56%.After 3 days,25%thiamethoxam WG 2000 times liquid and 50%dinotefuran SG 2000 times liquid showed better efficacy,with a corrected control effect greater than 81%,while other treatments were below 80%.After 7 days,the corrected efficacy of 50%dinotefuran SG 2000~4000 times liquid and 25%thiamethoxam WG 2000~4000 times liquid were all above 90%,followed by 10%imidacloprid EC 1000 times liquid,20%chlorantraniliprole SC 2000 times liquid,and 25%thiamethoxam WG 8000 times liquid,with corrected efficacy above 82%.In production,50%fipronil SG 2000~4000 times liquid,25%thiamethoxam WG 2000~4000 times liquid,10%imidacloprid EC 1000 times liquid,and 20%chlorantraniliprole SC 2000 times liquid can be alternately used for prevention and control.
