西藏冬虫夏草寄主比如蝠蛾生物学特性的研究

Study on the Biological Character of the Host of Cordyceps sinensis, Hepialus biru in Tibet

目的 观察比如蝠蛾生物学特性,为人工培殖冬虫夏草提供科学依据。方法 在冬虫夏草产地通过野生和人工饲养比如蝠蛾,观察各虫态的生物学特性。结果 比如蝠蛾幼虫土栖、世代重叠、多食性、6～8龄、幼虫期6年左右。蛹具有变色习性,在土中随发育变化和土温上升逐渐向地表移动。成虫主要完成羽化、交尾、产卵等生殖过程,7月中旬为羽化盛期,雌蛾平均产卵600余粒,历期40余天。卵椭圆形、黑色有光泽,具变色习性,对温、湿度有很强的依赖性,卵期70余天。结论 在观察各虫态生物学特性的同时,必须重点掌握幼虫的生物学特性。

objectiveThe biological specialities of Hepialus biru were observed in order to provide scientific rule for cultivating Cordyceps.MethodThe main biological specialities of Hepialus biru in field and in feedingby man were observed and compared.ResultThe larva of Hepialus biru resided in soil. With generation over lapping, multi-feed and 6-8 periods, and exist for 6 years so on. Its chrysalis can change color and rise to ground apperance with its development. The main activities of its imago is sex mating and bearing egg.The femail imago can bear 600 eggs so on. Its bearing-egg period is 70 days.ConclusionAfter understanding the biological habits of Hepialus biru , we can do better in cultiviating Cordyceps Sinensis by man.
