Bird flea

Ceratophyllus garei is an ectoparasitic insect belonging to the order Siphonaptera and the family Ceratophyllidae. Physically, it is a typical wingless flea with a laterally compressed, brown-colored body.

Adults measure between 2 and 4 millimeters in length. Their mouthparts are specialized for piercing the skin and feeding on the blood of warm-blooded hosts, particularly birds.

The insect possesses powerful hind legs, enabling it to jump significant distances, which facilitates movement between nests and individual birds.

Identification of the species requires microscopic examination of the body bristles and the structure of the male genitalia. Morphologically, it is similar to the chicken flea but exhibits specific life-cycle traits.

The biology of this species is closely tied to the presence of nesting material. Unlike many other species, this parasite can survive for extended periods in the external environment.

This species does not damage agricultural plants as it is an obligate hematophage. The primary damage occurs in poultry farms and captive bird collections.

The main hosts include various species of wild and domestic birds, particularly waterfowl, as well as ground-nesting species under specific conditions.

Parasitization leads to restlessness in birds, reduced productivity, weight loss, and deterioration of feather quality. In some cases, anemia may be observed in young birds.

The pest acts as a mechanical vector for pathogenic microorganisms and can contribute to the spread of infectious diseases within a flock.

Economic damage stems from the necessity of expensive sanitary measures and a decrease in marketable product output.

The activity of Ceratophyllus garei is directly dependent on temperature and humidity levels within poultry houses or natural nests.

The peak reproduction period coincides with the bird nesting season, when sufficient organic debris and moisture accumulate in the nests.

In heated facilities, the life cycle may continue year-round without a distinct diapause, ensuring the constant presence of the parasite.

Optimal conditions for larval development are high humidity and moderate temperatures, which are characteristic of bedding material.

As cold weather approaches, the insects may enter a dormant state but quickly reactivate when environmental temperatures rise.

One of the first signs of infestation is noticeable restlessness in the birds, which begin to preen constantly, pluck their feathers, and display aggression.

Inspection of housing areas often reveals clusters of insects in wall cracks, bedding, and nesting boxes.

Young birds may show stunted growth and pale skin due to regular blood loss caused by the bites of adult parasites.

Finding adult fleas on the skin of human workers in a poultry house is a direct indicator of a high level of infestation in the premises.

A characteristic sign is the presence of the parasite's black excrement in the bedding, resembling grains of ground pepper.

The primary method of control is comprehensive sanitary treatment of the premises using contact-action insecticide products.

A crucial step in protection is regular replacement of bedding and disinfection of nesting boxes, where the majority of larvae congregate.

• Mechanical cleaning of surfaces to remove dust and droppings.
• Application of specialized insecticides in spray or powder form.
• Implementation of biological methods for insect population control.
• Maintenance of an optimal microclimate with moderate humidity.

Preventive inspections of birds should be conducted, and individuals showing signs of infestation must be isolated to prevent the spread of parasites.

The use of traditional methods, such as wormwood or tansy, provides only temporary repellent effects and must be combined with professional disinfestation.
