| 摘 要： | 本文研究了稻纵卷叶螟发生量与生态因素间的数量关系。明确了影响田间成虫数量的主导因素是成虫迁入强度和植株密度;影响卵量的主导因素是成虫数量和叶色;影响幼虫数量的主导因素是卵量和天敌。分别组建了回归方程,这些方程可作为亚模型纳入到稻纵卷叶螟系统模型中进行数量预报,改变过去预报防治“一刀切”的现象。在电子计算机上检验河南各地材料,吻合度为20/25。

| Abstract: | Studies on relationship between ecological factors and the incidence of rice leafroller, Cnaphalorocis medinalis, were carried out in Henan Province in 1983-1986. The results indicated that the adult population in fields was affected primarily by immigration intensity of adults and plant density; number of eggs affected by adult population and leaf color; and larva number by amount of eggs and natural enemy. A series of equations were established, and they might be used as submodel in a systematic model to forecast the incidence of this pest. |
