目的 分析不同诱饵在北京通州地区诱集蝇类数量及种群构成的差异，为北京地区蝇类生态学监测及控制提供科学依据。方法 分别使用臭豆腐、糖醋水和鲜虾仁作为诱饵，采用笼诱法诱蝇。采用非参数检验方法对不同诱饵诱集的蝇类结果进行分析。结果 3种诱饵共捕获蝇类30种、8 322只，平均蝇密度为24.05只/笼。臭豆腐、糖醋水和鲜虾仁3种诱饵捕获蝇类数量差异存在统计学意义(H_c=25.59,P<0.01);蝇密度分别为43.93只/笼、3.78只/笼、24.78只/笼。蝇种密度排名前7位的是丝光绿蝇、白头亚麻蝇、厩腐蝇、红尾粪麻蝇、黄须亚麻蝇、亮绿蝇、大头金蝇。结论 不同诱饵诱集蝇类数量和种群构成存在差异，应依据实际工作的目的和要求，选择最适合的诱饵。

Objective To analyze the differences in the number and population composition of flies trapped by different baits in the Tongzhou District, Beijing, so as to provide scientific basis for ecological monitoring and control of flies in Beijing. Methods Flies were captured by cage trapping method using stinky tofu bait, sugar-vinegar bait and fresh shrimps bait, respectively. Non-parametric test methods were used for the statistical analysis of the results of the trapping effect of different baits on flies. Results A total of 8 322 flies in 30 species were captured by three baits, with an average fly density of 24.05 flies per cage. There were statistically significant differences in the number of flies captured by stinky tofu, sugar-vinegar and fresh shrimp(Hc=25.59, P<0.01). The fly densities were 43.93, 3.78, and 24.78 flies per cage, respectively. The top 7 fly species in density were Lucilia Sericaca, Parasarcophaga(s.str.) albicep, Muscina stabulans, Bercaea haemorrhoidalis, P.(s.str.) misera, L. illustris, and Chrysomya megacephala. Conclusions There are differences in the number and population composition of flies trapped by different baits. The most suitable bait should be selected based on the purpose and requirements of practical work.
