【摘要】 以云南元阳传统品种稻作生态系统和建水杂交品种稻作生态系统为基地,采用黑光灯和Malaise诱捕器于2007年系统调查了元阳、建水稻作生态系统中半翅目昆虫群落组成,并分析了其群落多样性特征。结果表明,滇南元阳和建水稻作生态系统中半翅目昆虫共有8科27种,突背斑红蝽Physopelta gutta(Burmeister)为优势种。元阳传统水稻品种种植区共诱集到半翅目昆虫6科19种,Simpson指数、Shannon指数和均匀度分别为0.65,2.03和0.48,建水杂交稻品种种植区共诱集到半翅目昆虫8科16种,其Simpson指数、Shannon指数和均匀度指数分别为0.61,2.27和0.57。综合两稻区半翅目昆虫群落多样性指数分析结果,滇南元阳县和建水县两地半翅目昆虫群落总体Simpson指数、Shannon指数和均匀度指数分别为0.63,2.18,0.44。Shannon指数时间动态表明,元阳、建水半翅目昆虫Shannon指数呈现两个峰期,分别是5月下旬～6月下旬和8月下旬。更多还原

【Abstract】 The community structure and dynamics of Hemiptera insects were investigated using black-light and Malaise trap in Yuanyang and Jianshui rice planting areas in 2007.Results showed that the Hemiptera insects belonging to 27 species in 8 families,there were 19 species of 6 families in Yuanyang and 16 species of 8 families in Jianshui county, and the Physopelta gutta(Burmeister) was the dominant species.The Simpson index,Shannon index and Eveness index was 0.65,2.03,0.48 respectively in yuanyang,and 0.61,2.27 and0.57 for the indices of Hemiptera insects in Jianshui. Overall,the Simpson index,Shannon index and evenness index was 0.63,2.18 and 0.44 for the Hemiptera insects community in southern of Yunnan province.There were 2 peaks according to the Shannon index in Yuanyang and Jianshui, and they were late May to late June,and late August respectively.更多还原
