Precipitating Antibody Concentrations and Visual Estimates Correlated to Absolute Northern Fowl Mite (acari: Macronyssidae) Densities from White Rock Hens
Fifty-four White Rock hens were infested with 2,000 northern fowl mites/ bird and six hens were sampled at nine time periods during the 28,week study. Hens supported an average of 15,028 mites when mites were collected from infested bird carcasses digested with a modification of the Cook's technique. Mite-specific Ilrccipitating antibodies were quantified from hen serum samples with rocket elec...
متن کاملAcaricide resistance in northern fowl mite (Ornithonyssus sylviarum) populations on caged layer operations in Southern California.
Southern California caged layer operations were visited over 3 yr. Northern fowl mites from 26 field populations were tested for acaricide resistance using a capillary pipette and glass dish bioassay. One was a susceptible field population with no pesticide exposure for over 30 yr (reference site for resistance ratio calculation). Technical and commercial formulations of malathion, carbaryl (Se...
متن کاملDermatitis caused by the tropical fowl mite Ornithonyssus bursa (Berlese) (Acari: Macronyssidae): a case report in humans.
We herein report human dermatitis caused by the tropical fowl mite Ornithonyssus bursa (Berlese). The cases occurred in an apartment in a residential district of Porto Alegre City, State of Rio Grande do Sul, Brazil, where three members of the same family presented with pruritic lesions on the arms and legs. On inspecting the bathroom, several mites measuring approximately 1.0mm in length were ...
متن کاملActivity of selected anticoccidials as feed additives for control of the northern fowl mite, Ornithonyssus sylviarum (Canestrini and Fanzago).
Three levels (high, low and control) of northern fowl mite, Ornithonyssus sylviarum (Canestrini and Fanzago), were maintained on White Leghorn hens for 24 weeks. The hens were then treated with carbaryl to eradicate the mites, were induced to molt, and were reinfested with mites 9 weeks later. Subsequent levels of mites on the three groups showed that the degree of acquired immunity was related...
متن کاملBEHAVIOR, CHEMICAL ECOLOGY Responses of Ornithonyssus sylviarum (Acari: Macronyssidae) and Menacanthus stramineus (Phthiraptera: Menoponidae) to Gradients of Temperature, Light, and Humidity, With Comments on Microhabitat Selection on Chickens
Responses of the northern fowl mite (NFM), Ornithonyssus sylviarum (Canestrini & Fanzago) (Acari: Macronyssidae), and the chicken body louse (CBL), Menacanthus stramineus (Nitzsch) (Phthiraptera: Menoponidae), to variation in temperature, light, and humidity were assessed in bioassays. The location on a continuous thermal gradient atwhich each ectoparasite arrested was recorded and analyzed. NF...
