杨扇舟蛾(Clostera anachoreta(Fabricius))是杨树叶部的重要害虫,在我国大部分省区都有分布。除危害杨柳树外,还危害母生。自五十年代以来,人们对它的生物学特性及防治作了大量的研究,但对害虫与寄主间关系的研究很少。在自然界中,我们发现环境条件差别不大的情况下,不同品种的寄主植物上杨扇舟蛾的发生有较大差异,为了探讨造成这种差异的原因,在室内用不同杨树品种对杨扇舟蛾进行了人工饲养,并化验分析了叶子中的化学成分。
Clostera anachoreta (Fabricius) is an important pest of poplar leaves, which is distributed in most provinces of our country. In addition to endangering willow trees, but also endanger the mother. Since the 1950s, a great deal of research has been done on its biological characteristics and its prevention and treatment, but little is known about the relationship between pests and hosts. In nature, we found that there was a big difference in the occurrence of Helicoverpa armigera on different species of host plants under the condition of little difference in environmental conditions. In order to explore the reasons for this difference, The moths were kept in captivity and the chemical constituents in the leaves were assayed.
