Abstract: Objective To explore the effect of different weight groups of sugar and vinegar bait to monitor fly density and provide scientific basis for control of flies. Methods During March-November 2015, the author selected 4 habitats of Jiading Park, residential area, restaurant and farmer's market were selected, trapping was conducted by fly cage, fly density was calculated and analyzed using Excel 2003 and SPSS 13.0 software to test the density of flies in different weight groups by means of rank and test. Results Five families of flies were captured, which belonged to 25 genera and 42 species. Twelve species of flies were identified by national vector surveillance program (Trial Implementation), accounting for 51.49% of the total catch. The predominant species consisted of Mascina stabulans, Boettcherisca peregrina, Lucilia sericata, Aldrichina grahami, Musca domestica, and L. illustris. The density of flies increased with the increase of bait weight, and the difference was statistically significant (H_C=9.188, P<0.05). Flies began to appear in March and disappeared in November. The seasonality showed peaks in June and October. The highest density of flies was observed after 1 d of sweet and sour bait. Conclusion The species, density, distribution and seasonal dynamics of flies were obtained by using sweet-sour bait to monitor flies.

摘要： 目的 探索不同重量组糖醋诱饵监测蝇密度效果，为蝇类防制提供科学依据。方法 2015年3－11月，选择嘉定区公园、居民区、中小饭店和农贸市场4种生境，采用捕蝇笼诱捕法捕获蝇类并计算蝇密度，使用Excel 2003和SPSS 13.0软件以秩和检验对不同重量组诱饵监测的蝇密度进行检验。结果 共捕获蝇类5科25属42种，其中采用《全国病媒生物监测方案（试行）》鉴定蝇种12种，占捕获总数的51.49%；优势种为厩腐蝇、棕尾别麻蝇、丝光绿蝇、巨尾阿丽蝇、家蝇和亮绿蝇。蝇密度随诱饵重量递增而增加，差异有统计学意义（H_C=9.188，P < 0.05）。蝇类3月开始出现，11月消失，季节消长呈双峰型，6、10月出现2个活动高峰。发酵1 d的糖醋诱饵监测的蝇密度最高。结论 利用糖醋诱饵监测蝇类可获得当地蝇种、密度、分布及其季节消长动态。
