自七十年代以来,花生蛴螬的发生面积、为害程度均有发展,受害花生一般减产2—3成,严重的7—8成,甚至绝产。为了探索应用乳状芽孢杆菌防治花生蛴螬的技术,一方面从国外引种鉴定,另一方面从国内自然资源中发掘自然感病的现状芽孢杆菌菌种以利就地利用。研究证明从美国引进的日本金龟乳状菌(Bac-illus popilliae Dutky)对我国优势虫种大黑鳃金龟感染力很低,无应用价值。我所1977年9月16日从山东临沭县大蔡庄大队花生田首次采到自然感染乳状菌的大黑蛴螬,通过多次取其体内病原进行注射、喂食证明对大黑蛴螬致病率特强并定
Since the 1970s, the occurrence area of peanut crickets has been greatly affected. The peanut yield is reduced by 2-3%, and the peanuts are seriously weakened by 7-8% or even absolutely dead. In order to explore the application of Bacillus cereus control peanut 蛴 螬 technology, on the one hand from the introduction of identification abroad, on the other hand from the domestic natural resources to explore the natural susceptibility to the status of Bacillus sp. For local use. Studies have shown that the introduction of the United States from Japan of the genus of milk turtle (Bac-illus popilliae Dutky) on China’s dominant species of black gill turtles infectivity is low, no application value. On September 16, 1977, from the peanut field of Dacaizhuang Brigade in Linshu County, Shandong Province, we first collected the natural black alsophila larvae of Mycoplasma nipponense, injected and fed many times to find out the pathogenicity to black alsophila Very strong and set
