Objective To compare the field capture effects of standing fly cages and hanging fly cages.Methods The fly densities were compared by paired samples Wilcoxon signed rank test,while the constituent ratios by x2 test and Fisher exact test.Results A total of 405 flies and 24 non-flies were captured.The composition ratio of flies by standing cages(97.12％)was higher than that by hanging cages(91.86％),with statistically significant difference(x2=5.614,P=0.018).The constituent ratio of fly species captured by the two kinds of fly cages was statistically significant different(x2=14.90,P=0.005).The density of flies was 12.5 flies per cage both by standing cages and hanging cages,without significant difference(Z=-0.922,P=0.357).Conclusion Both standing fly cages and hanging fly cages can be applied for fly monitoring and control.Users can make choice reasonably according to the actual situation.
