Abstract: Objective To investigate the luring effects of different formulae of fly baits, and to explore the commercialization and standardization of baits for fly monitoring. Methods Nine formulae of fly baits were prepared from jam, sweet bean sauce, brown sugar, milk powder, putrid fish paste, and fish meal at different ratios. The fly- luring effects of the fly baits were compared by cage trap method. Results Formula 5 (rotten fish paste＋sweet bean paste) had the highest trapping rate for Chrysomya megacephala, and formula 6 (rotten fish paste＋brown sugar＋milk powder) had the highest trapping rate for Musca domestica, as shown by the test which was performed at 3 rotations per month for 4-11 months. M. domestica accounted for 29.3% of all captured flies. The chi-square test revealed that formula 6 was significantly different from formulae 1-3 and 5, but without significant differences from formulae 4 and 7-9. The Student-Newman-Keuls test showed that formula 6 was better than other formulae, i.e., formula 6>formulae 9, 7, 4, and 8>formula 2>formula 3>formula 5>formula 1. Conclusion Formula 6 is better than other formulas and thus can be used for field fly monitoring and comparison. Further investigation deserves to test its luring effects on M. domestica and other fly species.
