冬虫夏草的寄主涉及鳞翅目蛹蛾科的蝙蝠蛾属(Hepialus)、类蝠蛾属(Hepialiscus)、二岔蝠蛾屑(Forkalus)和双节蝠蛾属(Bipectius)37种昆虫,其中蝙蛹蛾属的虫草蝙蝠蛾(H.armortcartus)、斜脉蝠蛾(H.oblifurcus)、德钦蝠蛾(H.deginensis)、白马蝠蛾(H.baimaensis)以及五龙蝠蛾(H.yulongensis)是冬草夏草的主要或优势寄主昆虫。虫草蝠蛾地理分布具有区域性、地带性,主要分布于我国的四川、青海、云南、西藏和甘肃等地,除虫草蝙蝠蛾为广域分布种外,其余种类均为狭域分布种。虫草蝠蛾生长在雪线以下3000m以上的海拔高度,垂直分布的上限为5080m,在高山草甸土中分布最多,高山寒漠土次之,再次是高山棕色针叶林土,其他类型土壤中未发现。虫草蝠蛾幼虫期长,一般2～3年,最长的4～5年,营地下生活主食高山草甸中的蓼属、黄芪属、柳属、无心属及杜鹃属等植物嫩根芽相地下茎,耐寒性强,过冷却点在-18.2℃～-21.5℃之间,无真正的滞育特性。虫草蝠蛾被冬虫夏草菌(’ordyceps sinensis(Berkely)Saccards寄生是在幼虫一年中第二次蜕皮(7～8月),感染寄生率为2.6～16.1％,以4～5龄期幼虫的寄生感染率最高,约占90％。
The host of Cordyceps militaris involved Hepialus, Hepialiscus, Forkalus and Bipectius of the Lepidoptera pupae, of which 37 were insects H. armortcartus, H. oblurica, H. deginensis, H. baimaensis and H. yulongensis, Is the main or dominant host grass winter grass insect. Cordyceps moths geographical distribution of regional, zonal, mainly distributed in China’s Sichuan, Qinghai, Yunnan, Tibet and Gansu and other places, Cordyceps bat moth is a wide-area distribution of species, the remaining species are narrow-range distribution species. Cordyceps moth moths grow at altitudes above 3000m below the snowline with an upper limit of vertical distribution of 5080m and are most often distributed in alpine meadow soils, followed by alpine deserts, again in mountain brown coniferous forests, and in other types of soils Find. Cordyceps moth larvae period is long, usually 2 to 3 years, the longest 4 to 5 years, the camp under the staple food alpine meadow polygonum, Astragalus, Salix, careless and Rhododendron and other plant root bud phase Underground stems, strong cold tolerance, subcooling point between -18.2 ℃ ~ -21.5 ℃, no real diapause characteristics. Parasitic moth was parasitized by ’ordyceps sinensis (Berkely) Saccards, the second molt (1-7 months) in one year of larvae with parasitic rates of 2.6-16.1%. Parasites of 4-5 instar larvae The highest infection rate, accounting for about 90%.
