质型多角体病毒(CPV复合剂)防治马尾松毛虫的研究

The prevention and cure experimental research on CPV against Dendrolimus punctatus

    摘要
  • 摘要: 报道了质型多角体病毒（ＣＰＶ 复合剂） 对马尾松毛虫防治效果的试验研究，筛选出菌毒复合剂Ⅰ、Ⅱ号防治效果最佳，林间虫口减退率达７６ ％ ，蛹期虫口减退率９８ ％ ，公顷用量Ⅰ号１２００ 亿ＰＩＢ，Ⅱ号２４００ 亿ＰＩＢ．

     

    Abstract: The prevention and cure effect of CPV on Dendrolimus punctatus is reported.The complex mixture of beauveria bassiana number ⅠandⅡ,which are the most efficient,were selected.The imago rate of population decreased by 76% in forest,the pupa rate of population decreased by 98%.The dosage perbectare for number Ⅰ is 1200 billion PIB,and that for number Ⅱ is 2400 billion.
