黑棒啮小蜂种团(膜翅目姬小蜂科)寄生蜂研究进展

Advance in parasitoids of the Tetrastichus howardi species group in Tetrastichus Haliday(Hymenoptera: Eulophidae)

啮小蜂属黑棒啮小蜂种团(Tetrastichus howardi species group)属膜翅目,姬小蜂科,啮小蜂亚科(Hymenoptera,Eulophidae:Tetrastichinae)。笔者详细介绍了该种团的识别特征和8种寄生蜂的地理分布、寄主种类、食性及生物学特性,系统综述了黑棒啮小蜂(Tetrastichus howardi)和白蛾黑基啮小蜂(T.nigricoxae)2种重要寄生蜂的生物学、行为学、人工繁殖与释放应用等方面的研究进展。在分析这些寄生蜂生物学共性与区别的基础上,还探讨了今后应用白蛾黑基啮小蜂防治杨树人工林食叶害虫的研究方向与利用对策。

Tetrastichus howardi species group in Tetrastichus Haliday belongs to Hymenoptera order,Eulophidae family,Tetrastichinae genus.Recognition feature of the species group and geographic distribution,hosts,feeding habits and biological characteristics of 8 parasitic wasps in Tetrastichus howard species group were introduced in detail.Research progresses on biology,behavior,artificial production and releasing technique of two important parasitoids,T.howardi and T.nigricoxae,were reviewed systematically,and that have important implications for future study on these parasitoid distributed in China.The common character and difference of these parasitoids＇ biology were discussed and research direction and application strategy of controlling poplar defoliator to use T.nigricoxae in the future were also explored in this paper.
