摘　　要：目的确定2006-2010年闵行区蝇类季节消长的高峰日和高峰时段,了解蝇类季节消长规律。方法采用圆形分布法统计分析闵行区2006-2010年蝇类密度监测数据。以圆形分布r值表示分布集中趋势。结果 2006-2010年共监测蝇388只,监测最高月份为7、8、9月,分别为91、70、67只;2006-2010年蝇密度分别为0.18、0.43、0.44、0.86、0.48只/(笼.日);蝇类平均密度高峰日为7月21日,高峰时段为5月30日至9月11日。年平均r值为0.6706,经假设检验2006-2010年不同年份及年平均r值相应的P值均<0.01。结论闵行区蝇类消长有明显的季节性规律。Objective To investigate the seasonal change of flies from 2006 to 2010 in Minhang district,in order to find out the seasonal change of flies. Method The circular distribution method was applied to analyze the fly density from 2006 to 2010 in Minhang. Results It showed that in Minhang district, there were 388 flies monitored from 2006 to 2010, and the peak of flies density distributed in 7,8,9 months, in which the number of flies were 97, 70 and 67 respectively. The annual fliesdensity were respectively 0.18, 0.43, 0.44, 0.86 and 0.48 flies every cage per day from 2006 to 2010. The peak day of flies seasonal change was July 21th.While the peak period of the seasonal change was from May 30th to Sep 1 lth.The annual r was 0.6706. The P values from 2006 -2010 were all less than 0.01 after tested by the method of hypothsis testing. Conclusion The numbers of flies had an obvious seasonal change feature from 2006 to 2010 in Minhang district.
