在自然条件下,虫生真菌疾病的病原种类或被寄生的昆虫数量都很多,利用昆虫疾病作为生物防治,国内已有报导,并认为是防治害虫的新方向之一。本文是1956年以来笔者在山东所见的虫生真菌种类、分布、寄生情况,并部分分离培养与接种的记要。一Entomophthora aphidis Hoffman寄主:菜缢管蚜(Rhopalosiphum Pseudobrassicae Davis)及桃蚜(Myzus persicae Sulzer)若虫及成虫;1957,5,济南桑园;1961,5,泰安白塔店;1964,5,泰安桑家(田仝)。5月间最易在白菜及蘿卜叶背采到虫生藻菌,但自6月中旬以后逐渐消失,田间发生情况随年分及不同部位有差異,5月间气温偏低而雨量
Under natural conditions, the number of pathogenic species of parasitic fungi or the number of parasitized parasites is very high. Utilizing insect diseases as biological control has been reported in China and is considered as one of the new directions for pest control. This article is a summary of the species, distribution and parasitism of parasitic fungi seen by the author in Shandong since 1956, and some of them were isolated, cultivated and inoculated. An Entomophthora aphidis Hoffman Host: Rhopalosiphum Pseudobrassicae Davis and Myzus persicae Sulzer nymphs and adults; 1957, 5, Jinan Mulberry; 1961, 5, Taian Baita shop; 1964,5, Taian Sang Home (Tian Tong).
