| 摘 要： | 浙江省丽水地区是马尾松毛虫白僵病自然常发区。近几年来采集并分离到球孢白僵菌9 个野生菌株。测定它们在PDA 平板上的营养生长和产孢量, 以及菌株对马尾松毛虫的致病力。结果表明, B2 , B4 和B14等3 个菌株致病力最强, 营养生长最快, 产孢量较高, 达3 亿个cm-2 , 在今后生产上对马尾松毛虫的防治最具应用潜力;次之是B7 , B10 , B11和B12等4 个菌株;而B6 和B13菌株的各个性状较差,几无潜力。同时也说明自然界中存在遗传多样性的自然菌株。表5 参6

| Abstract: | Nine strains of Beauveria bassiana , collected from Lishui , Zhejiang , a natural epidemic area , were isolated during April to September .The test showed that three strains (B2 , B4 and B14) were the best on their mycelium growth , sporogenous ability and pathogenicity to masson-pine caterpillar , four strains (B7 , B10 , B11 , and B12)were the second best , and two strains (B6 and B13) were the worst .Consequently , B2 , B4 and B14 strains have applied-potentiality to control masson-pine caterpillar in future . |
