摘要:

【摘要】 目的 了解南昌城区蝇类组成、季节消长及不同生境、不同月份蝇类种群的多样性特征。方法 蝇种调查采用笼诱法;多样性测度采用多样性指数与均匀性指数。结果 南昌城区蝇类优势种为家蝇、大头金蝇、丝光绿蝇。蝇类密度季节消长在5-6月出现一个春季高峰,在9月出现一个秋季高峰,多样性指数与均匀度指数在5月最高,分别为0.4036和0.4229,在4类生境中以农贸市场的多样性指数与均匀度指数最高,分别为0.4768和0.5280。结论 多样性指数与均匀度指数可反映城区蝇类群落特征。

Abstract:

【Abstract】 Objective To illustrate the composition, seasonal fluctuation and the diversity of flies  at different habitants in different months in Nanchang. Methods Cage trapping method was used for the monitoring of fly density, and the species diversity index and evenness index were employed. Results The dominant species of fly were Musca domestica, Chrysomya megacephala and Lucilia sericata in Nanchang. There were two peaks in one year, one in May to June, and the other in  September. The species diversity index and the evenness index were the highest in May, reaching 0.4036 and 0.4229 respectively. In 4 different habitants, both indexes were the maximum in farm market, which were 0.4768 and 0.5280, respectively. Conclusion The population characteristics of flies can be reflected with the species diversity index and the evenness index.
