Haematopinus suis

Haematopinus suis, commonly known as the hog louse, is a species of sucking louse that specifically infests domestic pigs (Sus scrofa domesticus). These parasitic insects belong to the family Haematopinidae within the order Phthiraptera.

Description

Haematopinus suis are small, wingless insects with flattened bodies adapted for clinging to the hair of their host. They have specialized mouthparts for piercing the skin and feeding on blood. These lice are typically light gray in color and can be found in various regions of the pig's body, such as the ears, neck, and back.

Life Cycle

The life cycle of Haematopinus suis consists of three main stages: egg, nymph, and adult. Female lice lay eggs, known as nits, which attach to the hairs of the pig. Nymphs hatch from the eggs and undergo several molts before reaching adulthood. Adult lice reproduce by mating on the host animal.

Effects on Host

Infestations of Haematopinus suis can cause irritation, itching, and discomfort to the host pig. In severe cases, heavy infestations may lead to anemia, poor growth, and decreased productivity in pig farming operations. Control measures such as parasiticides and proper hygiene practices are essential for managing louse infestations.

Prevention and Treatment

Preventing Haematopinus suis infestations involves maintaining good hygiene in pig housing facilities, regular monitoring for signs of lice, and implementing appropriate control measures. Treatment options include the use of insecticidal products specifically designed for louse control in pigs.
