摘要
不同病原真菌对光肩星天牛Anoplophora glabripennis(Motsch)幼虫致病力的测定表明:粉拟青霉9101、球孢白僵菌Z28 和卵孢白僵菌寄生率均为100% ,粉拟青霉Z26为87.5% 。各种菌对光肩星天牛的最适致死温度是:粉拟青霉Z26 15℃~20℃;粉拟青霉9101 15℃~25℃;球孢白僵菌Z28 20℃~30℃。用自己分离所得的球孢白僵菌Z28,粉拟青霉Z26,以含孢量4 亿孢子/m l+ 0.02% 增效剂做林间塞孔防治试验,每种处理与对照相比差异极显著。球孢白僵菌Z281~3 次/年处理间无明显差异,防治效果达93.44% ~97.25% 。粉拟青霉Z261~3 次/年处理间无明显差异,防治效果在92.92% ~96.55% 。两种菌混合塞孔,以1~3次/年处理间无差异,防效达93.64% ~96.48% 。每株树所用菌剂成本为0.02元。
The experiments show that all the lethal rate of Paecilomyces farinosus 9101, Beauveria bassiana Z 28 and B.brongniartii on Anoplophora glabripennis are 100%,and P.farinosus Z 26 on the insect is 87.5%.The optimum lethal temperatures are: for P. farinosus Z 26 15℃~20℃; P.farinosus 9101 15℃~25℃; B.bassiana Z 28 20℃~30℃.The pathogens with a concentration of 4×10 8spores/ml+0.02%synergist are used to fill the holes bored by A.glabripennis .The mortalities of larvae are all above 92%.
