Controle da infestação por Ornithonyssus sylviarum (Canestrini e Fanzago, 1877) (Acari: Macronyssidae) em poedeiras comerciais utilizando extrato de Azadirachta indica

Abundance and temporal distribution of Ornithonyssus sylviarum Canestrini and Fanzago (Acarina: Mesostigmata) in gray catbird (Dumatella carolinensis) nests.

The northern fowl mite, Ornithonyssus sylviarum Canestrini and Fanzago, is a common ectoparasite of wild birds. Despite its ability to transmit eastern equine encephalitis (EEE) virus under laboratory conditions and potential for involvement in the natural EEE virus cycle, we know little about its abundance or temporal distribution in nature. From June to August 2000, we studied the abundance o...

Activity 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...

BEHAVIOR, 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...
