纵卷叶螟绒茧蜂(Apanteles cypris Ni-xon)是稻纵卷叶螟幼虫期寄生蜂中最重要的一种,一般寄生于低龄幼虫,将幼虫消灭在暴食之前,对控制稻纵卷叶螟有良好的作用。为摸清对稻纵卷叶螟的寄生效能,为保护、利用提供依据,81年我们对纵卷叶螟绒茧蜂进行了初步观察,现将结果整理如下。 Apanteles cypris Ni-xon is the most important species of the parasitic wasps in the larvae of the rice leafroller. It is usually parasitized to young larvae and eliminated the larvae before gluttony. Borer has a good effect. In order to find out the parasitic potency of the rice leaf roller, in order to provide the basis for protection and utilization, we conducted a preliminary survey of the leaf roller Tetranychus celtis in the past 81 years.
