Control tests of non-biting stable flies in poultryfarm

Abstract

In summar of 1963, three organophosphorus insecticides, i.e., Nankor (Ronnel), Sumithion and Dipterex, were tested against natural population of non-biting stable flies, Muscina stabulans Fallen, breeding in manure under poultry cages in Saitama area. All applications were made with mortor compression sprayer at 500ml of emulsive dilution containing 0.05% of each insecticides per one square meter, and the treatments were repeated every two weeks. Fly population was evaluated by collecting the flies with paper or ribbon traps which were located at poultry farm or dwellings. All the insecticides gave good control of the stable flies breeding in poultry manure after the second treatment. After the third spraying, however, population of house fly, Musca domestica vicina Macquart, was markedly increased with the depression of the stable fly, although the house fly larvae did not breed in the chiken manure treated with the insecticides.
