  大豆胞囊线虫病病原为大豆胞囊线虫(Heterodera glycines),该病害严重影响大豆产量.由于目前对环境污染的重视和对无公害农产品的需求,线虫生物防治受到国内外的广泛关注.但是,关于寄生真菌代谢物对大豆胞囊线虫趋性的影响却研究较少,本试验在实验室条件下采用滤纸片法和直接法,以淡紫拟青霉(Paecilomyces lilacinus)4个菌株:P-1、P-V-7-2、P40-4、P-E-13-2;镰孢菌属(Fusarium spp.)4个菌株:F-1、F-5、F-9-3、F-V-1-4;厚垣轮枝菌(Pochonia chlamydosporium)4个菌株:V-25-3、V-1、V-2、V-21-2为研究对象;探讨12种寄生真菌代谢物滤液对大豆胞囊线虫二龄幼虫的趋性影响,为利用寄生真菌防治大豆胞囊线虫病和生防真菌田间应用提供数据参考.
