External Parasites of Poultry
نویسنده
چکیده
External parasites most commonly infesting poultry in California include the northern fowl mite, the common poultry mite, several kinds of lice-and the chicken tick, which is often called the blue-bug in spite of the fact that it is a true tick. In some of the warmer dry areas of the state, stick-tight fleas and western hen fleas become troublesome. Losses suffered from such parasites are often hidden but are reflected in the form of decreased egg production, slow weight gains, and generally poor condition. The northern fowl mite usually spends its entire life on the bird, although in heavy infestations, large numbers of it may be found roving about the premises. Sulphenone and neotran dusts and sprays are effective for control of this parasite, although for most situations sulphenone is more suitable. A thorough application of either material to the birds is required for adequate control.
