摘要
试验表明：从樟萤叶甲虫尸上分离的白僵菌，经过室内扩大再培养，生产出含孢量１００亿／ｇ菌剂，制成手雷式粉炮，用菌量６ｋｇ／ｈｍ２，防治第１－２代樟萤叶甲幼虫，效果可达７２．５％－８７．７％；调成２亿／ｍｌ浓度的菌液喷雾防治第１代幼虫，效果可达８７％－８９％。
The experiment indicated that
Beauveria bassiana,isolated from the corpses of Atysa ,marginata in-sects,was used to
produce microbial inocula with 10000 million spores per g by means of the expansive anoth-er
culture indoors,The antitank grenade-type powder cannons were made with the microbial
inocula to con-trol A. marginata larvae of the first-second generation,the amount of microbial
inocula used was 6kg/hm2and the effect could reach 72.5-87.7%,When the microbial inocula
were blent into liquid with the concen-tration of 200 million spores per mI to control the
first-generation larvae through spraying, the control effect could reach 87-89%。
