Abstract: Objective To compare grid method, vision method, sticky trap method, and cage trap method in terms of the surveillance results of fly density and to provide a basis for effective application of grid method in the surveillance of fly density. Methods Surveillance of fly density was performed inside and outside the farmer’s market according to GB/T 23796-2009 Surveillance Methods for Vector Density-Fly. Results In the indoor surveillance, the fly density measured by grid method was lower than those measured by sticky trap method and vision method, but without significant differences between them. There was a strong correlation between the fly densities measured by grid method and vision method(r＝0.933 489,P＝0.000), and a good correlation was also seen between those measured by grid method and sticky trap method(r＝0.791 836,P＝0.004). In the outdoor surveillance, the fly density measured by grid method was lower than that measured by vision method and a little higher than that measured by cage trap method, but without significant differences between them. There was no correlation between the fly densities measured by grid method and vision method(r＝0.408 318,P＝0.212), but a good correlation was seen between those measured by grid method and cage trap method(r＝0.848 092,P＝0.001). Conclusion Grid method can be used for the surveillance of fly density. It can serve as a substitute for vision method and sticky trap method in the indoor surveillance and for cage trap method in the outdoor surveillance.
