Abstract

Abstract

The pathogenicity of Beauveria bassiana strain XJBb3005on the adult of Myllocerinus aurolineatus was evaluated by using the adult immersion assay.The results showed that the mortality of M.aurolineatus increased with the concentration of the conidia and immersion time, and 100% mortality is caused by the applying of 108conidia/mL on day 7.A time-dose-mortality model was employed to analyze the bioassay data and the model fitted the data well, resulting in parameters for estimating the time and dose effects.The estimated LC50and LC90value were 4.86×104and 4.26×106 conidia/mL on day 7, respectively.At the immersion concentrations of 1.0×108, 1.0×107, 1.0×106, 1.0×105 and 1.0×104conidia/mL, the estimated LT50values were 3.97, 4.45, 5.01, 6.49and 7.87d, respectively;the LT90values were 4.98, 6.48and 7.84dat concentrations of 1.0×108, 1.0×107 and1.0×106 conidias/mL, respectively.These results suggest that B.bassiana XJBb3005is benefit for the biological control of M.aurolineatus.
