Control of the haematophagous fly Hippobosca maculata, a series pest of equines, by deltamethrin.

This study reports the results of both a small-scale and a large-scale field treatment to assess control of the haematophagous fly Hippobosca maculata Leach a serious pest of equines in a stud in India using a deltamethrin based formulation, Butox. In the small-scale field trial application of 2 litres of deltamethrin at 0.001-0.003% concentration gave 90-100% control over 30 days. At 0.004% and 0.005% concentrations complete control was recorded for 45 and 90 days respectively. Mass application of 2 litres of 0.005% deltamethrin to equines and bovines controlled infestations of H. maculata for 1 year.
