中文摘要：
2008年5月至10月采用目测法与网捕法调查湖北省武汉市水生蔬菜地昆虫群落结构，共采集到11目、48科、104种，共计9 169头昆虫，其中，莲缢管蚜Rhopalosiphum nymphacae (L.)、茭白长绿飞虱 Prodenia litura (Fabricius)、斜纹夜蛾Saccharosyne procerus (Matsumura)、荸荠白禾螟 Scirpophage praelata (Scopoli)以及菱角莹叶甲Galerucella birmanica 是主要害虫，蜻蜓、瓢虫是主要天敌昆虫。通过群落结构分析表明：在不同植被类型的水生蔬菜地中，昆虫群落多样性差异较大，水芹的昆虫群落多样性最高，莲藕最低；水芹昆虫群落最稳定，荸荠次之，莲藕昆虫群落多样性前后期低，中期高，茭白前后期高，中期低。
英文摘要：
The insect community structure in different types of aquatic vegetables in Wuhan were investigated with visual method and net method from May to October of 2008. The results showed that there were 9 169 individuals belonging to 11 orders, 48 families, 104 species. Rhopalosiphum nymphacae (L.), Prodenia litura (Fabricius), Saccharosyne procerus (Matsumura), Scirpophage praelata (Scopoli) and Galerucella birmanica (Jacohy) were the main pests, and Odonata and Coccinellidae were the primary natural enemies. The analyses on community structure indicated that the diversity index of insect community were remarkably different in different vegetations, which was the highest in water dropwort, and was the lowest in lotus. Insect community structure on water dropwort was the most stable, and water chestnut was at the second place. The diversity index of insect community in lotus was high in middle period, but low in early and late periods, whereas that in water bamboo was low in middle period, but high in early and late periods.
