卵孢白僵菌Beauveria tenella)是蛴螬病原真菌,寄生于大黑鳃金龟(Holotrichiadiomphalia)和暗黑鳃金龟(H.morosa)。蛴螬感染病菌后,食量减退,行动迟慢,在虫体胸、腹节、足基部出现微小黑褐色病斑,病虫僵死后,体表长出棉絮状菌丝,最终形成粉末状的白色孢子团。1983—1984年我们对金河、彭口闸、沙沟等乡镇大豆田进行了调查,自然寄 Beauveria tenella is a rickety mildew pathogenic fungus that is parasitic on Holotrichiadiomphalia and H.morosa. After the infection of bacteria, the appetite decreases and the action slows down. After the tiny black-brown spots appear on the thorax, abdominal section and foot base of the parasites, after the pests are dead, the cotton-like mycelium grows on the surface of the body and finally the powdery white spores group. From 1983 to 1984, we conducted a survey of township soybean fields such as Jinhe, Pengkouzha and Shagou.
