【摘要】 布氏白僵菌是寄生于蛴螬的一种虫生真菌,田间试验表明:每公项用量22.5、37.5、52.5kg依次可降低虫量60.4%、70.1%和82.5%,减低花生被害果72.7%、74.8%和85.9%。中耕期防治效果略高于播种期防治,尤其是对夏播花生防治后增产效果明显。菌药混用有较好的增效作用。不同菌株的防效有明显的差别。本文还讨论了布氏白僵菌防治土壤害虫的生态条件和进一步研究的问题。更多还原

【Abstract】 Experiments were carried out in Anhui Province in 1990—1994 on study of the effectiveness of using an entomopathogenic fungus Beauveria brongniartii to control the white grubs （Holotrichia morosa） in peanut fields.When different rates of preparation at 3.0×10¹²—7.4×10¹²spores/mu,to soil were used,the population level of the white grubs and damage of peanut were decreased 61.4%～82.5%and 72.7%～85.9%respectively.Synergic effectiveness was made if fungus preparation was mixed with low dose of sublethal insecticide.Result showed that preparation of B.brongniartii applied to the soil at the time of cultivative period was better than sowing time. Comparison of three strains of B.brongniartii to control white grubs in peanut fields showed that effectiveness was no different between the Jilin no.4 and the Bio-isolate no.5, but the HF89-1 was rather lower virulence than above strains. B.brongniartii has been used in larger area in Anhui province for controlling white grubs in peanut fields.更多还原
