The present study evaluated delta traps baited with oviposition attractant mixture (OAM), (Z)-9-Tricosene and a combination of both (OAM+(Z)-9-Tricosene) in the control of houseflies in the poultry farm. The OAM was prepared with Ethyl palmitate, Ethyl linoleate, Methyl linoleate and Linoleic acid in 10:24:6:0.2 proportions. Traps were evaluated in two trials; in trial-I, OAM was prepared with liquid paraffin as solvent and in trial-II with acetone as solvent. In trial-I, the highest number of flies were trapped in OAM+(Z)-9-Tricosene baited traps followed by (Z)-9-Tricosene baited traps, OAM baited traps and control traps. In trial-II highest number of flies were trapped in OAM+(Z)-9-Tricosene baited traps, followed by OAM baited traps, (Z)-9-Tricosene baited traps and control traps. There was a significant difference (p<0.01) in the number of flies trapped with different baits. A clear variation in sex of flies trapped was observed with highest male to female sex ratio noticed in (Z)-9-Tricosene baited traps in both trial-I (3.44: 1) and trial-II (3.12:1) and lowest male to female ratio in OAM baited traps in both trial-I (1.69:1) and trial-II (1.39:1). Fly densities evaluated before and after the trial using spot cards revealed 12.4 and 6.8% reduction in the fly spots for trial-I and trial-II, respectively. Based on the observations, it can be concluded that baited delta traps can be effectively employed in integrated fly management strategies to control houseflies. OAM can be used as an efficient bait to trap female flies and can be combined with other baits like pheromone (Z)-9-Tricosene for increased effectiveness.
