Control of Musca domestica (House Fly) in poultry units using delta traps

House fly menace is a major problem in poultry farms and nearby households. Though application of insecticides is one of the major approaches in house fly control, development of insecticide resistance is widely prevalent. Use of house fly traps is an ecofriendly alternate strategy in control of house flies. In the present study, delta traps were used to control house flies in poultry units.

Red acrylic delta traps with two different pellet baits (FMP and FMPB) were placed at ground level in poultry units housing caged layer chicken with a distance of 90 cm between two traps for seven days continuously and trial was replicated six times. Trapped flies were counted, sexed and species identified. Spot cards were used to determine house fly density pre-and posttrapping. Correlation of house fly population with meteorological parameters was assessed.

Out of the 80410 flies trapped, 52.74 per cent (42415 flies) and 47.25 per cent (37994 flies) were trapped in FMPB and FMP pellet baited traps, respectively. Daily fly trapping pattern showed variations. Overall trap catches were dominated by female flies. Reduction in spot card count was 36.34 per cent after deployment of traps. Trap catches correlated positively with temperature, relative humidity and wind velocity. Two species Musca domestica domestica and Musca domestica vicina were identified.
