BACKGROUND/AIM House flies (Musca domestica) are of major public health concern in areas with poor sanitation and hygiene conditions. Biological control through the use of parasitoids and pathogens is one of the alternatives to the use of chemical pesticides for control of insects of public health importance. MATERIALS AND METHODS The effects of the delta endotoxin of Bacillus thuringiensis o...
House flies are of major concern as vectors of food-borne pathogens to food crops. House flies are common pests on cattle feedlots and dairies, where they develop in and feed on animal waste. By contacting animal waste, house flies can acquire human pathogenic bacteria such as Escherichia coli and Salmonella spp., in addition to other bacteria, viruses, or parasites that may infect humans and a...
Three natural populations of house fly Musca domestica were analyzed for eight genetic loci by means of polyacrylamide gel electrophoresis (PAGE). Allozyme analysis at eight loci scores nineteen putative alleles. The amount of mean observed heterozygosity (Ho) was greater for Varanasi population than the other two populations studied. Nei’s genetic identity (I) and distance (D) values reveal th...
An Integrated Management program to control Musca domestica L. was developed by evaluating cultural 1 chemical control, cultural 1 biological control 1 granular bait (IMP 1), and cultural 1 chemical 1 biological control 1 granular bait (IMP 2) in poultry houses in Argentina. Adult fly density was estimated by a modified Scudder-grid method. Percentage of house fly parasitism was estimated by di...
House fly and stable fly pupae were collected during the summer from a dairy farm in northern Illinois. Spalangia nigroaenea accounted for most of the parasitoids recovered from house flies. Spalangia nigra, S. endius, Muscidifurax spp., and S. nigroaenea accounted for most of the parasitoids from stable flies. The majority of flies were house flies late in the summer and stable flies early in ...
Acoustical characteristics of a stage house and their effects on auditorium acoustics were investigated in a proscenium hall using computer simulation and scale models. The effects of a fly tower, the upper part of a stage house, were investigated with variable upper batten densities and covering materials. In addition, influences of the lower part of the stage house were examined by controllin...
Seasonal genetic variation was assessed in the common house fly Musca domestica. Allozymes at six gene enzyme system viz., ACPH, EST, G6PD, ME, AO and XDH were analyzed. Fourteen loci with twenty seven alleles were unraveled. The genetic variations were found to be affected to a great extent by environmental influence .F statistics has been used to calculate genetic variation which revealed tha...
House flies are among the most important nonbiting insect pests of medical and veterinary importance. Larvae develop in decaying organic substrates and their survival strictly depends on an active microbial community. House flies have been implicated in the ecology and transmission of enterococci, including multi-antibiotic-resistant and virulent strains of Enterococcus faecalis. In this study,...
House flies are a ubiquitous insect that have the potential to spread many diseases to humans and livestock. Managing house fly populations is accomplished by having desirable baits, traps, and killing agents. Most house fly baits are designed for outdoor use or limited indoor use, and have a foul odor that is not conducive to food preparatory and dining areas. Blackstrap molasses has long been...
The problem of house fly has become more acute everywhere especially in poultry and piggery farms. They act as potential vector for many viral, bacterial, helminthic and protozoan diseases and as nuisance pests. The control of fly is very much effected by the use of synthetic organic insecticides. These drugs, even though efficacious, can be detrimental to the mankind and environment and also l...
