摘要：对宁夏、陕西、甘肃的落叶松叶蜂Pristiphora erichsonii、河北的落叶松锉叶蜂P.laricis和落叶松腮扁叶蜂Cephalcia lariciphila、山西靖远松叶蜂Diprion jingyuanensis、陕西松阿扁叶蜂Acantholydaposticalis、云南的祥云新松叶蜂Neodiprion xiangyunicus和南华松叶蜂D.nanhuaensis的幼虫及茧期病原真菌调查统计,并从以上虫茧中分离出真菌13株,初步鉴定球孢白僵菌Beauveria bassiana8株、布氏白僵菌B.brongniatii 4株、青霉属Penicillium sp.1株。选取5株白僵菌以3龄月季叶蜂为试虫进行毒力测试,结果显示1.0×108孢子/mL菌液对试虫有致死作用,校正死亡率69.5%～91%。
The pathogenic fungi of several pine sawflies, ie Pristiphora erichsonii in Ningxia, Shaanxi and Gansu,P. laricis and Cephalcia lariciphila in Hebei,Diprion Jingyuanensis in Shanxi,Acantholyda posticalis in Shaanxi,Neodiprion xiangyunicus and D. nanhuaensis in Yunnan Province were surveyed. Thirteen strains of pathogenic fungi were identified including 8 strains of Beauveria bassiana ,4 strains of B. brongniatii and one strain of Penicillium. Five strains of Beauveria sp. were tested with larvae of Arge geei in the 3rd instar. The result showed at the concentration of 1.0 x 10^8 spore/mL,the corrected mortali- ty was 69. 5%-91.0%.
