| 摘 要： | 纹瓣真片叶蜂Eutomostethus reticulatusWei是毛竹(Phyllostachys pubercens Mazelex H.de Lehaie)的食叶害虫。该虫适应毛竹2年萌发1次新叶的特性,多数个体也是历经2年发生1代。以预蛹在土茧中越夏越冬,于第2年或第3年春天羽化出土。幼虫为害期为4月上旬~6月上旬,5月上旬起老熟幼虫陆续入土预蛹。1年1代的预蛹历期近11个月,2年1代的预蛹历期近23个月。报道该虫各虫态的形态特征和生物学特性。

| Abstract: | Eutomostethus reticulates Wei is the pest injuring leaves of moso bamboo （ Phyllostachys pubescens Mazel ex H. de Lehaie）. Adapting to the life history of moso bamboo which burgeons fresh leaves every 2 years, major proportion of this sawfly need 2 years for one generation. It aestivated and hibernated as prepupa in the soil pupal cocoons. It emerged in the second or third spring and crawld out of soil. Larvae were found from early April to early June. From early May, the matured larvae entered into soil for pre-pupation. Prepupa of one generation each year lasted nearly 11 months, while one generation every two years lasted nearly 23 months. The morphology and bionomics of each stage were reported. |
