摘　　要：对云南省昭通地区发现的蛹虫草进行了初步调查,其寄主昆虫为鹰翅桦尺蛾,1年1代,以蛹越冬,幼虫取食华山松叶,为当地华山松纯林的主要害虫,危害高峰期为9月中旬至10月上旬。蛹虫草主要发生于海拔2 200-2 400 m的华山松人工纯林,发生期为气候温和,降水丰沛,空气湿润的夏末秋初季节(7月下旬至9月下旬)。成分分析表明,该虫草营养成分丰富,含有646.0 g.kg-1的蛋白质,37.0 g.kg-1的粗脂肪,54.3 g.kg-1的总糖,35 g.kg-1的灰分,17种氨基酸,氨基酸总量为266.3 g.kg-1,还含有多种人体代谢所必需的无机元素。The Cordyceps militaris found in Zhaotong ,Yunnan Province was investigated. The host insect is Biston falcata, which has one generation a year in Zhaotong and overwinters by pupae. The larvae eat the needles of Pinus armandii Franch, and therefore is a harmful pest of the pine from mid September to early October. Cordyceps militaris mainly lives in annand pine forest with the altitude of 2 200 - 2 400 m. Its fruit bodies occur from late July to late September, in the mild,moist and rainy habitat. Analysis indicated that the fungus had rich nutrition ingredients including 646.0 g·kg^-1 protein,37.0 g·kg^-1 crude fat, 54.3 g·kg^-1 total sugar,35 g·kg^-1 ash ,and 17 kinds of amino acids. Total quantity of amino acids is 266.3 g·kg^-1. Many kinds of inorganic elements needed in human metabolism are included.
