XII. Livestock and Poultry Insects

M. P. Nolan, Jr. and D. C. Sheppard

During 1996, horn flies on beef cattle; and stable flies on beef cattle,  dairy cattle and horses were major concerns to livestock producers in Georgia.  Lice, primarily blood sucking lice on swine and beef cattle, caused production problems.  Mites, mostly northern fowl mites on poultry breeders and layers and sarcoptic mites on swine, were damaging.  In broiler operations, litter beetles were of most concern.  House flies caused public relations and nuisance problems near some livestock and poultry facilities.
