摘要
研究双季晚稻主要刺吸式口器害虫在时间和垂直序列上的生态位，测定出生态位宽度和相似性比例指数，评价它们在双季晚稻田中的竞争、共存机制，为制定双季晚稻刺吸式口器害虫综合防治措施提供科学依据。
The ecological niche,the width and ratio index of similarity of the niche of major pest with stabing mouth on late rice of double-cropping paddy fields were investigated.The mechanism of competition and co-existance of the pest in the fields was discussed.
