These lice have no blood-sucking mouthparts. They feed by chewing, using ventral mandibles like teeth. These mandibles also are used to grip onto hairs or feathers, and there is a groove in the ventral surface of the head to fit hairs or feather shafts.

Goniocotes gallinae the fluff louse

Palps are absent at the mouthparts. The three segments of the thorax are fused together, and the boundaries between them are indistinct. The claws of the legs do not articulate onto a distinct tibial claw as often seen in the sucking lice.

The ischnoceran lice that infest domestic animals are in two families. The Trichodectidae infest mammals: The Philopteridae infest birds: Bovicola bovis Red or chewing-louse of cattle infests cattle on their neck, shoulders, back and rump. Bovicola ovis Red or chewing-louse of sheep infests sheep on their back and upper regions of their body; B. Irritation and pruritus leads to restless self-grooming. Note that in comparison to an infestation of sheep with psoroptic scab mites Bovicola lice do not directly cause the skin to form moist scabs, the surface of the skin will appear intact, although with heavy infestations self-grooming may damage the skin.

Biting-stress leads to loss of production from heavy infestations. Bovicola bovis feeding activity can cause damage to the appearance of processed hides.

This damage is known as spot and fleck. This occurs despite the superficial feeding of these lice [1]. Felicola subrostrata is the only species of louse likely to be found on domestic cats. Effective self-grooming seems to protect most cats from harmful levels of infestation.

However, sick, very old cats, or long-hair breeds may suffer from their infestations with this louse [2]. Trichodectes canis Dog chewing-louse infests domestic dogs on their head, neck and tail. It also infests wild canids.

This species may need to be distinguished galline Heterodoxus spiniger on dogs in countries where both species of chewing lice occur. Heavy infestations produce irritation and biting-stress, leading to restlessness and much self-grooming.

Goniocotes gallinae (De Geer, ) – Taxonomy

Such infestations lead gallibae the hair-coat having a lousy appearance: This louse is an intermediate host for the tapeworm of dogs, Dipylidium caninum. The dog becomes infected when it ingests infected lice that it has groomed off [3].

Goniocotes gallinae Fluff-louse commonly infests poultry, amongst the down feathers over most of the body. Infestations are usually slight, but heavy infestations damage the plumage and cause restlessness leading to reduced productivity of poultry [4]. Gonoides dissimilis Brown chicken-louse and G. These lice feed on feathers and underlying skin over galliane parts of their host’s main body. They cause irritation, pruritus, restlessness, repetitive grooming, debility, and reduced productivity.

Lipeurus caponis Wing-louse infests the underside of wings and tail of chickens. Cuclotogaster heterographus Head-louse infests chickens on the skin and feathers gallibae their head; sometimes extending onto the neck [5].

ADW: Goniocotes gallinae: CLASSIFICATION

Young birds are particularly harmed by these lice; infestations can build up rapidly, leaving the birds weak and even killing them.

Lice in this group are similar in feeding habits to the ischnoceran lice because they feed with chewing mouthparts. Mouthparts are supplemented with a pair of palps next to the chewing mandibles.

Antennae have 4 or 5 segments, but they are less visible than in the ischnoceran lice because they occupy an antennal groove in the head.

On the ventral surface gnoiocotes the head a pair of backward directed spines is usually visible. The thorax appears in two parts: This division is clearest on the dorsal surface.

Claws on the legs are variable, one or a pair depending on the genus. Amblyceran lice mostly parasitize birds, but also are found on marsupial mammals, and mammals in the Americas. Heterodoxus spiniger infests domestic dogs and other canids, also marsupial mammals.

This species may need to be distinguished from Trichodectes canis on dogs in countries where both species of chewing lice occur. Heterodoxus spiniger has also been reported infesting domestic cats but where the cats were close to heavily infested dogs [6].

Pathological effects are only likely if the host is already in poor condition from other parasites or malnutrition. This louse is an intermediate host of the tapeworm of dogs, Dipylidium caninum. Heterodoxus spiniger is considered to have evolved in Australia.

It has spread to tropical and sub-tropical regions of the Americas, and to Africa. Menacanthus stramineus Chicken body-louse infests chickens, other poultry species, aviary and game birds. Infestations are particularly dense on the breast, thighs, and around the vent. Irritation, pruritus, and restlessness cause loss of production.

Infestations with the actively mobile M. The lice may penetrate the blood vessels at base of feathers, leading to anemia. This combination of pathological effects often greatly reduces productivity of a flock. This species is the most damaging of the bird lice [7]. Menopon gallinae Shaft-louse infests chickens, turkeys and ducks on their breast and thigh feathers.

It feeds only on the feathers and these lice can be seen in rows clasping a feather shaft [8]. Heavy infestations in young birds may be highly damaging but this louse is rarely a severe pest to adult birds.
