Abstract

The house fly, Musca domestica have been implicated in the mechanical transmission of pathogens causing diseases. Important diseases that may be transmitted under certain conditions include infection of virus, bacterial, protozoan, fungal and helminthic. Therefore control measures should be carried out only when the presence of the house fly is intolerable to humans due to their being a health hazard or nuisance. The larvicide with active ingredient of dichlorvos 250 g/1 was applied to the house fly larvae which conducted in the laboratory. There were fIve concentrations of larvicides to be tested i.e. 6: 12; 24; 48 and 96 ml by product/ 3 I of water/m2. A dried powder of chicken dung was utilized as larvae medium. The medium was inoculated with the third instar larvae then it sprayed with the larvicide suspension. All larvicidal assays were carried out at 26 - 30°C temperature and 60 - 80% RH in the laboratory. The results revealed that all of the five tested concentrations yielded between O and 5.2 percent larval mortalities,
