Laboratory Rearing Methods for Three Common Species of Bird Mites

Abstract
Methods are descr. for rearing Liponyssus bursa, L. sylviarum and Dermanyssus gallinae in sheet metal chambers. A moat at the top, containing oil or water, prevents the mites from escaping. Sterilized grass is packed into the bottom of each chamber, and water and feed trays for young chicks (which serve as hosts) are provided. The chicks are usually 2 or 3 days old when first introduced and about 15 days old when replaced with fresh chicks. D. gallinae and L. bursa thrive under laboratory conditions. L. sylviarum is more exacting in its requirements, especially as to humidity. The mite chambers are kept in a thermoregulated-room at 80-83[degree]C, a temp. satisfactory for both young chicks and all the mites.
