LICE AND MITES ON POULTRY Zll Biting Lice on Poultry Several different species of biting lice affect poultry, including the genera Menopon, Lipeurus, and others. They vary in particular characteristics, but all are alike in the fact that they do not suck the blood of their host, but cause injury by eating the surface of the skin and the fuier parts of the feathers, and by the tiny pricks of their sharp claws as they move about over their host. On young chicks their irrita- tion may readily prove fatal. The eggs or " nits " are laid on the feathers, and in warm weather hatch in ten days. Both young and adults are apt to be especially active at night, crawling over the perches and moving from one fowl to another. Treatment must include both the poultry house and the fowls in order to be entirely effective. The latter may be dusted with a mix- ture of 10 pounds of sulphur to 5 bushel of air-slaked lime. The same material may be used in the house, taking care to get it into all cracks, and mixing it with the dust bath. A more effective measure for the house is spraying with lime-sulphur solution or 10 per cent kerosene emulsion. Treatment of the fowls should be repeated at the end of a week or ten Fig. 604.—A Chicken Louse, Li- peurus variabilis. Enlarged and natural size. Original. The Chicken Mite {Bermanyssiis gallincE Redi.) Several species of mites attack poultry, but the commonest is the one here described. It is a minute, eight-legged creature, one twentieth of an inch long, normally grayish in color but appearing red when filled with blood. It has sucking mouth parts. Eggs are laid in droppings or in places where dirt has accumulated, and the young feed at first on such substances. Later they crawl on.
