Study on ControllingOligia vulgaris by Using Beauveria bassiana

Oligia vulgaris was one of the main pests for bamboo shoots.The virulences of 5 Beauveria bassiana against O.vulgaris were compared,the result showed that Bov07 strain had the best infectious effect,then the Bpp04 strain.Their corrected mortality respectively reached 83.33%,73.81%,with LT50 of 7.3 d and 9.2 d.Then powder of Bov07 strain was produced for field test,when the dose was 22.5 kg·hm-2,the control effect was over 80% after 15d long post inoculation,So the strain of Bov07,was highly virulent to O.vulgaris which could be served as biocontrol agent for O.vulgaris.
