Andraca bipunctata is one of the main leaf-eating pests of Camellia oleifera,and it is widely distributed in Fujian Province,China.In this study,biocontrol experiments were conducted against A.bipunctata larvae using a spore suspension and powder of Beauveria bassiana in a C.oleifera forest of Shanghang County.The results showed that the mortality rate of the larvae increased over time when the pests were treated with a concentration series of 1.0×105,1.0×106,1.0×107,1.0×108,and 1.0×109 fungal conidia·mL-1.After 9 days of spraying the spore suspension,mortality rates of the larvae at concentrations of 1.0×107,1.0×108,and 1.0×109 conidia·mL-1 were 81.6％,84.6％,and 85.9％,respectively;the corrected mortality rates were 79.9％,83.1％,and 84.5％,respectively.The average mortality rate of the larvae was 73.7％after 9 days of treatment with the powder of B.bassiana conidia at 7.5 kg·hm-2.These findings provide a scientific reference for the control of A.bipunctata larvae by B.bassiana.
