云南松毛虫蛹的综合利用研究

Study on Integrated Utilization of Pine Moth Pupa

用不同浓度的玉米螟微孢子虫悬浮液，饲喂及浸泡感染1、2、4、7龄云南松毛虫幼虫。

Various corn borer microsporozoites were used to feed and soak Dendrolimus honi larvae at the instar of 1,2,4 and 7 for infecting them .

培养在国内外首次利用云南松毛虫虫卵和幼虫组织进行体外培养。

This was the first time that people cultured the egg and larva tissues ofDendrolimns kikuchii Matsumura of Yunnan in vitro in and out of China .

通过样方调查计算，采用聚集度指标法，测定云南松毛虫越冬代幼虫的空间分布型，建立了最适抽样数关系式，并对其进行了序贯抽样分析。

According to quadrate investigation , using aggregation index , we measured the spatial distribution pattern , set the optimum sampling relationship , and made the sequential sampling analysis .

从生命表可以看出，云南松毛虫种群数量在很大程度上受自然环境因素制约，第一代和越冬代的死亡率分别为9976%和9988%。

It was deduced from the life table that population number was significantly affected by the natural and environmental factors , the death rate of the first generation and overwintering generation were 99 76 % and 99 88 % respectively .
