Abstract
Effect of triflumuron, a benzoylphenylurea, to inhibit the fly emergence from chicken feces was examined under a simulated field condition. Thirty 0.5 kg fecal samples, collected from a poultry house, were divided into 5 groups of 6 samples each and each sample was placed in a container. One of the 5 groups was used as the non-treated control and another group was sprayed with 300 ml tap water per m2 bottom area of container. The remaining three groups were sprayed with 300 ml triflumuron-water suspension to give 250 mg triflumuron per m2 bottom area, 500 mg/m2, and 1000mg/m2, respectively. The numbers of adult flies, Musca domestica, emerging from the fecal samples wefe 18.8±4.4 (average ±SD) and 18.3±3.8 in the non-treated and the water sprayed groups, respectively, whereas those in the triflumuron sprayed groups were 9.0±0.6 in 250 mg/m2 group, 6.8±0.8 in 500 mg/m2 group, and 1.2±0.4 in 1000 mg/m2 group. Deformed pupae were recovered from the fecal samples treated with triflumuron. From these results, it is concluded that triflumuron is sufficiently larvicidal against fly larvae in chicken feces.
