Sticktight flea

Taxonomy: The sticktight flea (Echidnophaga perilis) is a member of the order Siphonaptera within the family Pulicidae. Unlike common fleas, this species is noted for its stationary behavior once it finds a suitable host, making it a persistent and difficult pest in poultry production.

Biology and Lifecycle: The biology of Echidnophaga perilis is characterized by the female flea attaching itself to the skin of the host. Once attached, the female embeds her mouthparts into the epidermis and remains fixed in that position for her entire adult life to feed on blood. This unique attachment mechanism ensures a continuous food supply and facilitates egg production.

Nature of Damage: The parasites prefer areas with minimal feather cover, such as the comb, wattles, and skin around the eyes and beak. The feeding activity creates lesions and sores, which are often aggravated by scratching, leading to deep skin inflammation, necrotic tissue, and secondary bacterial infections.

Economic Impact: High infestation levels can cause severe anemia, weight loss, and stunted growth in young poultry. In cases of intense infestation, the physical damage to the head area can obstruct the bird's vision or interfere with eating, potentially leading to mortality and significant losses in productivity.

Control Measures: Management of the sticktight flea requires a combination of sanitation and chemical treatments:

• Regular and thorough cleaning of poultry houses to remove flea larvae and breeding sites.
• Application of approved insecticides to the environment and directly to the affected birds.
• Maintaining strict biosecurity to prevent the introduction of new infested birds.
• Continuous monitoring of the flock for signs of attachment around the eyes and comb.
