主 题：maize arthropod community diversity evenness
摘 要：This study is to integrate pest management （IPM） of maize insect pest. The paper reports the current condition of species diversity of maize field in Nanning, Guangxi Province. All exper/mcntal materials were collected dur/ng the stages of tasseling, blister, milk, maturity and after reaping respectively from 5 plots from April to July, 2007. The Shannon-Wiener index（H）, Simpson index（H＇）, Brillouin index（J）, species evenness（E） and richness index （Dmc） were used into analysis of abundance and distribution characteristics of communities and populations of major arthropods in maize fields. Result showed that a total of 19 arthropods, belonged to 10 orders and 18 families, were obtained from maize fields. Of which there are 12 pest insects, 3 natural enemy insects, 2 spiders and 2 middle insects. All of the community diversity indices were the highest in maize fields after reaping. No significant difference was found between other 4 various stages i.t. tasseling, blister, milk and maturity stages. The results of this study will help to carry out the IPM of maize field pest insect.
