应用佳多诱虫灯进行室外昆虫群落调查

利用佳多诱虫灯对菜田与棉田室外昆虫群落结构做了初步的研究,并利用丰富度(S)、优势度(B)、SHANNON指数(H’)、均匀度(E)4个指标和种—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了对比分析。结果表明棉田灯下昆虫群落中小型趋光性害虫葱蓟马被大量诱捕,该群落优势种突出,优势度较高。佳多诱虫灯是室外害虫调查和物理防治的有用工具。

Investigation to Outdoor Insect Community with Jiaduo Insect Trape Lamp

A preliminary investigation on the structures of the outdoor insect communities in vegetable and cotton fields with Jiaduo alluring insect 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）, Dominance （ B）, SHANON （ H^＋ ） and Evenness （E）. The results showed that a lot of Thrips tabaci, a kind of minitype photokinesis pest, were trapped in a cotton field insect community of lamp, moreover the dominant species and the dominant degree of this community were greater than another＇ s. In conclusion, Jiaduo lamp is a useful tool of outdoor pest＇s investigation and physical control.
