In the present study, different electric and solar traps for house flies using food baits as lures were fabricated and the field efficacy of the traps was evaluated in poultry units. Six different traps were designed and tested for their efficacy in luring and killing house flies. They were electric trap 6V, solar trap 6V, solar trap 12V, cylindrical solar trap, bilateral solar trap and inverted cone solar trap. All six traps were provided with electric grid for killing the trapped flies. Traps were deployed at ground level in fly infested areas in the poultry units at the layer breeder house at Poultry Research Station, Madhavaram, Chennai. The testing of each trap was repeated six times. Unbaited traps were used as control. Number of trapped flies was counted. The solar trap 12V was found to be most effective when compared to solar trap 6V and electric trap 6V. Out of the total 11065 flies trapped, 54.91 per cent (6076 flies) were trapped in the 12V solar trap followed by 35.58 per cent (3937 flies) in solar trap 6V and 9.50 per cent (1052 flies) in electric trap 6V. Variation in trap catches using electric trap 6V, solar trap 6V and solar trap 12V was highly significant statistically (χ2 value = 5170.24** p<0.01HS). The cylindrical solar trap, bilateral solar trap and inverted cone solar trap were comparatively less effective in trapping flies.
