| 摘 要： | 大螟成虫产卵对寄主植物种类和生育期有明显选择性。寄主植物种类和理化性状影响幼虫的成活率,蛹体重量和性比,从而影响成虫产卵量,表明寄主植物对大螟种群数量有明显的影响。幼虫在田间的分布状况主要也是由于田边寄主植物更适合其生长发育之故。

| Abstract: | Sesamia inferens(Walker) is one of the major insect pests in the regions of Tai Lake and Yangzi River. In the middle of 1970''s, population of the insect increased year after year. However, since 1982, it decreased rapidly. It seems to be that the dynamic of S. inferens was related to the changes of cropping system as well as the host plant varieties. In this paper, the relations between the development of S. inferens and its host plants were investigated. |
