Parasitic Insects, Mites and Ticks: Genera of Medical and Veterinary Importance/Chewing lice

Por favor,activa el Lipeurud All lice species liipeurus affect poultry and most domestic birds belong to the group of Mallophaga or bird lice. There are more than 40 species worldwide. Most of them are cosmopolitan, i.

In most cases infested birds carry lice of several species simultaneously. Many species infest poultry as well as other domestic birds such as turkeys, pigeons, guinea fowls, ducks, geese, etc. Adult lice are rather small insects 1. They are found mainly in and around the feathers, especially at their base, and on the body surface.

They have strong chewing mouthparts and feed on feather and skin debris as well as on body exudates. Some species may even feed on blood that comes out of the wounds they produce.

Lice are obligate parasites that spend their whole life on the caponus They are hemimetabolic, i. Adult females lay eggs nits at the base of the feathers’ shafts. Each female lays up to a few hundred eggs during her lifetime, depending on the species. Eggs are visible for the naked eye as whitish masses, frequently at the base of the feathers.

Larvae hatch 4 to vaponis days after egg deposition and develop progressively to nymphs and adults. The lifecycle takes 3 to 5 weeks to complete, depending on the species. Lice live for various months, but off the host capknis won’t survive more than a week. Since temperature and humidity remain quite constant on the body surface of the birds, lice populations are not very susceptible to seasonal changes in climatic and ecological conditions, especially indoors.

Transmission of lice is by contact between birds, typically from hens to chicks. Therefore spreading of lice within a bird flock is mainly driven by crowding that favors close contacts. Cuclotogaster heterographathe head louseis about 2. It prefers to stay close to the skin or at the base of the feathers. It does not suck blood, but feeds on skin and feather debris.


It is more frequent on young birds and turkeys. Heavy infested birds may even die before maturity. It is rather large 2. It feeds mainly on feather debris, but is capable of sucking blood.

It lives mostly on the skin of birds, seldom on the feathers, and prefers body parts with few feathers, e. The eggs are laid in clusters on the feathers or directly on the kin. Goniocotes gallinaethe fluff louseis one of the smallest lice of poultry, only 0.

Lipeurus caponis (Linnaeus, ) – Taxonomy

It is found all over the birds’ body, but less densely on the head and the wings, on the fluff or base of the feathers. It also feeds mainly on feather debris. Lipeurus caponisthe wing louseis 2. It is found mainly in the inner part of wing, tail and head feathers. It only feeds on parts of the feathers, but so intensively, that is also called the depluming louse. Menopon gallinaethe shaft louseis rather small 1.

It feeds mainly on skin and feather debris, but may also suck blood from the wounds it produces.

3. Lipeurus caponis (Linnaeus)

It prefers the chest, the shoulders and the back of birds. Eggs are whitish and are laid often in clusters at the base of the feathers. Columbicola columbaethe slender pigeon louseis 2. It can be found all over the body, especially at caponia inner side of the wing feathers. It feeds on feather debris. Eggs are laid preferentially are the small feathers under the wings. Infestations with a few lice are usually harmless for the birds. But massive infestations can substantially reduce performance and reproduction.

Lice bites are irritating: They may even injure themselves. Lice are usually a problem only on poultry kept under traditional conditions, especially on layers.

They are usually not a problem in modern industrial poultry operations, although outbreaks can happen in layers and even in breeding lipfurus kept under poor conditions. The broiler cycle is mostly too short to allow the build up of large lice populations. The first priority to avoid outbreaks of lice on poultry houses is to prevent the introduction of lice from outsidesince wild birds can transmit most lice species.


The second measure is to prevent dissemination of lice between poultry housesif one of them becomes infested.

Nests of wild birds in or around the facilities have to be destroyed. Whatever equipment or hardware is moved between poultry houses cages, baskets, crates, boxes, trays, etc. Good caponix of infestations without using synthetic lousicides has been lipeirus with thuringiensinthe exotoxine of Bacillus thuringiensisdirectly applied on infested birds. However, commercial products with thuringiensin may not be available everywhere for use on poultry, although acponis are quite common lipeuruz agriculture.

Lice remain always on the birds. Consequently, chemical control with whatever lousicides has to be directly administered to the birds and not to the facilities or the environment of the birds.

Dipping is lipeurjs frequent but will work as well. Dusting also works and it allows treating the birds indirectly, e. However, roosters and cocks don’t dust themselves like hens and it may be necessary to treat them separately. Laying hens have to be treated directly. Care must be taken particularly with some organophosphates that may be toxic to birds if slightly overdosed. However, at the therapeutic dose they are unlikely to control poutry lice. In most countries they are not aproved for poultry at all: There are no repellentsnatural or synthetic that will keep lice away from poultry.

So far there are no effective biological control methods against poultry lice. Learn more about biological control of insects. Click here if you are interested in medicinal plants for controlling lice and other external parasites of poultry, other livestock and pets.

This means that if a particular product has not achieved the expected control, it is most likely because the product is not adequate or it was not used correctly, not because lice have become resistant.
