Abstract
Beauveria bassiana was tested to infect the 2nd larvae of Stilpnotia candida at 25 ℃ with different relative humidity. It was proved that the pathogencity of Beauveria bassiana and the mortality of larvae were higher at high humidity. The LT50 for the 2nd larvae were 6.799, 8.325, 10.672 and 12.597 d at 25 ℃, with (95±5)% , (85±5)%, (75±5)% and (65±5)% relative humidity, respectively.
