赤水桫椤自然保护区桫椤尺蛾科害虫的初步研究

A preliminary study on the individual development of viridifasciata of the Alsophila spinulosa pests in Chishui

在近些年的观察中发现对桫椤造成危害的害虫不止桫椤叶蜂一种,还有一种同样以桫椤为寄主的尺蛾科害虫,其危害程度较桫椤叶蜂而言更胜。现对该尺蛾科害虫进行了相关的调查研究,主要通过野外观察采样和室内人工饲养对其生物学特性的研究,掌握其适应机制,为以后采取针对性的防治措施提供基础数据,从而能更好地进行桫椤的保护。

The recent observation found that except Rhopographus cyatheae , there is another more dangerous insect viridifasciata that hosted in and harmed Alsophila spinulosa . Through field observation and sampling, and indoor artificial breeding, the biological characteristics and adaptation mechanism of the moth viridifasciata were studied, in order to provide basic data for targeted prevention and control measures in the future, so as to better protect Alsophila spinulosa against disease.
