摘要
利用灭蚊灯对室外昆虫群落结构进行研究，并利用丰富度（S）、优势度（B）、SHANNON指数（H′）与均匀度（E）4个指标和种一多度对数正态分布模型参数对两个灯下昆虫群落的结构进行对比分析。结果表明：市售灭蚊灯在室外昆虫调查和小规模防治中很有应用价值，可以简便地为生物实验室收集多种生态环境下的万余昆虫标本，是生物学课外活动与大棚害虫物理防治的有用工具。
A preliminary investigation on the structures of the outdoor insect community with the alluring mosquito lamp was carried out in this paper, and the differences of two communities of lamp were analyzed using the Preston＇ s lognormal distribution parameters of species-abundance model and four ecological indexes--Richness（S）,Dominant（B）, Shanon--Wiener index（H′ ） and Evenness （E）. The results showed that the commercial alluring mosquito lamp adapts to the outdoor insect＇ s investigation and the small scale control, and more than 10,000 species can be gained by it simply. In conclusion this lamp could become a useful tool of the extra-curricular activities of biology and the physical control in vegetable greenhouse.
