引种云南产冬虫夏草寄主蝠蛾的生物学特性研究

Study on biological character of Hepialus introduced from Yunnan province

目的:为人工培殖冬虫夏草选择优质的虫种提供理论依据。方法:在常规的饲养方式条件下引种研究云南产剑川蝠蛾Hepialus jianchuanensis的生物学特性。结果:在四川康定室内环境条件下,蛹期约40d,全天可以羽化;雌、雄性比约为1.2:1,成虫交配高峰在19:30-20:30,成虫期约25d,个体寿命雌蛾为5～6d,雄蛾为6～7d;成虫产卵量平均300粒左右,卵100粒重平均为10.33mg;幼虫期为350d左右,初孵幼虫具有多食性和一定的耐寒性。结论:引种的剑川蝠蛾与康定基地饲养的其他寄主生物学特性在生活历期、卵的100粒重以及腹内余卵数量等方面有一定的差异。

Objective:To study the biological character of Hepialus introduced from Yunnan province.Method:H.jianchuanensis introduced from Yunnan was bred artificially to observe its biological character.Result:The pupa duration was about 40 d,pupa emergence lasted for one day,female to male ratio was about 1.2:1,the mating peak was 19:30-20:30,the adults duration was about 25 d,the average life time of female was 5-6 d and that of male 6-7 d,the average number of the producing egg was about 300,the average weight of ...
