冬虫夏草,简称虫草,是虫与菌的结合体,为麦角菌科(肉座菌)虫苹属真菌类植物。冬虫夏草菌寄生在鳞翅目蝙蝠蛾科蝙蝠蛾属昆虫绿蝙蝠娥或草蝙蝠蛾等幼虫上的菌座(子实体)及幼虫的尸体。虫草菌的子囊孢子成熟后,随风飘扬,散落在土壤中,到了冬季,遇到蛰居在土壤中过冬的蝙蝠蛾幼虫,就钻入其身体里,以极强的生命力萌发成菌体,吸收幼虫体内的营养而生活,直至将整个幼虫体全部占据。到了夏天,当冻结的表土消融,土壤温度升高 Cordyceps sinensis, referred to as Cordyceps sinensis, is a combination of an insect and a bacterium, and belongs to the genus Fungi of the family Lactobacillaceae (Hyperctococcus). Cordyceps sinensis is parasited in the corpses (fruiting bodies) and larvae of lepidoptera bat moths, bats, insects, green bat bats, grass bat moths and other larvae. After mature, the ascospores of Cordyceps sinensis splattered in the soil as they fluttered in the wind. In the winter, they met the bat moth larvae that lived in the soil during the winter, and they penetrated into their bodies and germinated into their bodies with strong vitality. The larvae live in nutrients until they occupy the entire larval body. In summer, when the frozen surface soil melts, the soil temperature rises.
