Feather mite

The genus Megninia belongs to the order Sarcoptiformes and the family Analgidae. These microscopic mites are recognized ectoparasites that inhabit the feathers of various avian species. While they do not infest crops, they are significant pests in the context of commercial and backyard poultry management.

These mites typically target chickens, turkeys, and other domestic fowl. They reside on the feather vanes, feeding on skin debris, feather follicles, and secretions. Their presence is usually detected through the degradation of feather quality and the visible irritation of the infested bird.

The life cycle of Megninia is entirely completed on the host bird, encompassing stages from egg to adult. These mites are highly adapted to the avian environment and can survive for short periods in the litter, allowing them to spread effectively throughout a flock in confined spaces.

Infestation symptoms include damaged, frayed feathers and skin lesions, which cause intense itching and distress to the bird. Severe infestations result in weight loss, increased stress, and a measurable decrease in egg production or growth rates among the poultry stock.

Control measures rely heavily on integrated pest management, including regular cleaning and disinfection of poultry housing.

• Application of approved acaricides on birds.
• Deep cleaning of nesting areas.
• Maintaining optimal humidity to inhibit mite development.
