  Louse - Wikipedia, the free encyclopedia
Lice, also known as fly babies, (singular: louse) (order Phthiraptera) are an order of over 3,000 species of wingless parasitic insects.
Lice attach their eggs to their host's hair with specialized saliva which results in a bond that is very difficult to separate without specialized products.
Lice are highly specialized based on the host species and many species specifically only feed on certain areas of their host's body.

 Mites and Lice
First of all, mites and lice are quite uncommon in pet birds (with the exception of a type of mite that may be found in budgies).
Lice commonly encountered in pet birds are the biting kind, and are found on the feather shafts of infested birds.
If you see mites or lice on a pet bird brought in to your store, you will never go wrong by recommending that the customer take the bird to an avian vet for diagnosis of the specific type of bug present, since it is now obvious to you that different insect parasites require different treatments.

 Lice (Pediculosis) : Bureau of Communicable Disease : NYC DOHMH
Lice are six-legged, wingless, insect parasites of humans, mammals (cattle, pigs etc.), and birds (chicken and other birds).
Lice are divided into two groups: lice found on mammals, which need blood for sustenance; and those found on birds, which chew on feathers and dandruff.
Pubic lice feed on human blood and remains attached at the sites of their feeding for a long period of time and can be considered as almost stationary.

 HAMILTON & DISTRICT BUDGERIGAR & CAGE BIRD SOCIETY INC.
Lice are wingless insects and are the most common external parasites of birds.
Lice lay sticky, triangular eggs or nits which adhere to the feathers in clusters in their favorite region of the body and after which they are popularly named -- head, body, fluff, shaft and wing lice.
Bird lice feed mainly on the surface layers of the skin, feather vanes and skin debris, but at least one species has been found to bite growing feathers, sucking the blood from the base of young quills or even gnawing at the skin surface until blood is drawn.

 Pediculosis-head lice Fact Sheet   (Site not responding. Last check: 2007-10-30)
Head lice are frequently found in schools and day care centers, and are easily spread from person-to-person.
Head lice are spread through direct head-to-head contact with an infested person or indirect contact with lice-carrying objects such as combs, brushes, hats or scarves.
Lice can be spread as long as they remain alive on the infested person or their clothing.

 Patuxent Product Abstract   (Site not responding. Last check: 2007-10-30)
The host specificity of avian lice (Phthiraptera) may be utilized by biologists to investigate the brood parasitism patterns of Brown-headed Cowbirds (Molothrus ater).
Lice are permanent hemimetabolic ectoparasites, a group found strictly on the body of the host, and they are transferred almost exclusively by bodily contact between hosts during care of young and at copulation.
The technique of examining the lice on cowbird fledglings to identify their foster parents would be much less costly than hiring a team of experts to determine parasitism patterns in the conventional way by finding hundreds of songbird nests.

 deseretnews.com | U. scrutinizes specialized lice
Utah scientists have discovered why feather lice that infect birds are the size they are, with large lice on big birds and little species on smaller avian hosts.
The scientists examined three possible causes: that small lice were better suited to cling to small birds and large lice to large birds; that they were able to feed better on feathers of a matching size; or that a size match meant they were better able to escape from the birds' preening.
When lice were moved from their normal hosts to birds of different sizes, they were not well adapted to hide, and they were more likely to be cracked in the bird's beak.

 Research Projects--K. P. Johnson
Avian feather lice (Ischnocera) specialize on several different microhabitats on the body of birds.
The second possibility is that lice specializing on different microhabitats evolved repeatedly, often on the same group of birds, resulting in convergence across avian feather lice.
The lice occurring on waterfowl are among the least specific of all avian lice.

It is believed that most cases of avian flu infection in humans have resulted from contact with infected poultry or contaminated surfaces.
The reported symptoms of avian influenza in humans have ranged from typical influenza-like symptoms (e.g., fever, cough, sore throat, and muscle aches) to eye infections (conjunctivitis), pneumonia, and other severe and life-threatening complications.
Poultry producers should strengthen biosecurity practices to prevent the introduction of avian flu into their flocks, be aware of the clinical signs of the avian flu in birds, and report suspicious signs to animal health authorities.

 Pediculosis body Fact Sheet   (Site not responding. Last check: 2007-10-30)
Body lice are spread from person-to-person through close direct contact with a lice infested area of a person or through sharing of unlaundered clothes or bedding that had recent contact with an infested person.
Because body lice spend most of the time on clothing except for short periods of time on skin when feeding, persons with body lice should not be treated with lice-killing medications.
To control body lice, clothing and bedding that had contact with an infested person should be washed and dried at the hottest temperature possible to kill the lice and nits.

 Phthiraptera
Specializations in the diet of lice underpin their major taxonomic divisions and they can be broadly separated into those that feed on skin debris, feathers and fur, and those that have specialized in blood feeding.
His study supported the monophyly of the Phthiraptera, with Anoplura and Rhyncophthirina forming a monophletic group, sister group to the Ischnocera; the Amblycera are the sister group of this assemblage.
Nevertheless, the familial relationships amongst most major groups of lice are poorly understood, and resolution of these relationships awaits an analysis of all available morphological data, as well as the gathering of molecular information.

 Lice - The Merck Veterinary Manual
Avian lice, which belong to the order Mallophaga, have a life cycle of ~3 wk and normally feed on bits of skin or feather products.
Because lice transfer from one bird species to another when the hosts are in close contact, other domestic and caged birds may be infested with species of Mallophaga that are usually host-specific.
Lice are usually introduced to a farm through infested equipment (eg, crates or egg flats) or by galliform birds.

 Avian insect pests, Avian Insect liquidator
"Avian Insect Liquidator" (AIL) is promised by company veterinarian and marketing manager to control a wide range of insect pests including flies, lice and cockroaches as well as arachnids such as spiders and mites.
A study on the effectiveness of AIL on lice in caged birds demonstrated AIL to eliminate lice from birds at the recommended dose rate of 1:20 dilution, during which time numbers of lice on birds in control cages (no treatment) were shown to increase by up to 90%.
Available in 100 ml and 500 mL ready-to-use spray container or as a concentrate which can be diluted in a pump pack, it is recommended that the AIL be applied by spraying birds and their environment completely, with particular attention given to cracks and crevices where insects hide and breed.
