摘要

为明确云南西双版纳州稻田纵卷叶类害虫的发生动态和种群结构,利用LED灯和扫网法调查了稻纵卷叶螟与其近缘种宽纹刷须野螟的成虫种群数量。结果表明,西双版纳稻田中,在水稻中后期,稻纵卷叶螟与宽纹刷须野螟共同存在。其中,水稻拔节期至抽穗前期以稻纵卷叶螟为主,水稻抽穗后期至成熟期以宽纹刷须野螟为主,特别是在成熟期宽纹刷须野螟代替稻纵卷叶螟成为优势种群。
        In order to understand population dynamics and structure of rice leaffolders in Xishuangbanna, Yunnan province, adult quantity of Cnaphalocrocis medinalis and its related species, C. patnalis, were investigated through LEDlight and sweep net. The results showed that C. medinalis and C. patnalis coexisted in mid-later period of rice in Xishuangbanna. In this paddy field, major population of leaffolders was C. medinalis in jointing stage to early-heading stage of rice, while it was C. patnalis in later-heading stage to maturing stage of rice; especially in maturing stage of rice,C. patnalis replaced C. medinalis and became the dominant population.
