    Dendrolimus houi Lajonquiere is a serious pest of the Cryptomeria ( Cryptomeria fortunei Hooibrenk ) in Fujian Province .

  2. 云南松毛虫蛹的综合利用研究

    Study on Integrated Utilization of Pine Moth Pupa

  3. 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 .

  4. 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 .

  5. 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 .

  6. 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 .
