摘　　要：为明确球孢白僵菌和金龟子绿僵菌在玉米植株内的定殖能力及公主岭霉素对其定殖率的影响,本研究以玉米秸秆颗粒为载体制备成载菌颗粒剂,将球孢白僵菌(Beauveria bassiana)(Bb)、金龟子绿僵菌(Metarhizium anisopliae)(Ma)和公主岭霉素(769)混合接种玉米植株,使球孢白僵菌和金龟子绿僵菌在玉米内定殖。结果表明:球孢白僵菌和金龟子绿僵菌联合接种组中两种虫生真菌的定殖率分别为47.5%和78%,均高于其他处理组,定殖能力最强。三种微生物农药联合接种组球孢白僵菌和金龟子绿僵菌的定殖率最低,分别为25%和50%。结果证明,球孢白僵菌和金龟子绿僵菌联用可相互促进彼此在寄主植物中的定殖能力,公主岭霉素能抑制球孢白僵菌和金龟子绿僵菌的增效作用,但与单一菌种接种时对寄主的定殖能力影响不显著。In order to determine the colonization efficiency of Beauveria bassiana and Metarhizium anisopliae in corn and the affection of gongzhulingmycin,three kinds of biological agents were inoculated together in corn with corn straw granule as a kind of microorganism-carrier.Colonization rate of B.bassiana and M.anisopliae were detected.The result shows that colonization rate of B.bassiana and M.anisopliae in treatment of B.bassiana with M.anisopliae was 47.5%and 78%respectively,significantly higher than other treatments and the control.Colonization rate of B.bassiana and M.anisopliae in treatment of three kinds of microbial agents were 25%and 50%respectively,lower than other treatments and the control.Our results indicated that combination of B.bassiana with M.anisopliae could increase the colonization efficiency each other.Gongzhulingmycin could inhibit the synergistic action of B.bassiana and M.anisopliae,but there is no significant effect on colonization efficiency of B.bassiana or M.anisopliae.
