Flies are insects of the order Diptera, the name being derived from the Greek δι- di- "two", and πτερόν pteron "wing". Insects of this order use only a single pair of wings to fly, the hindwings having evolved into advanced mechanosensory organs known as halteres, which act as high-speed sensors of rotational movement and allow dipterans to perform advanced aerobatics. Diptera is a large order containing an estimated 1,000,000 species including horse-flies, crane flies, hoverflies and others, although only about 125,000 species have been described.
Leishmaniasis is a disease caused by parasites of the Leishmania type. It is spread by the bite of certain types of sandflies, and occurs most frequently in the tropics and sub-tropics of Africa, Asia, the Americas, and southern Europe. The disease can present in three main ways: cutaneous, mucocutaneous, or visceral. The cutaneous form presents with skin ulcers, while the mucocutaneous form presents with ulcers of the skin, mouth, and nose. The visceral form starts with skin ulcers and later presents with fever, low count of red blood cells, and enlarged spleen and liver.
Indiana vesiculovirus, formerly Vesicular stomatitis Indiana virus is a virus in the family Rhabdoviridae; the well-known Rabies lyssavirus belongs to the same family. VSIV can infect insects, cattle, horses and pigs. It has particular importance to farmers in certain regions of the world where it infects cattle. This is because its clinical presentation is identical to the very important foot and mouth disease virus.
Sandfly is a colloquial name for any species or genus of flying, biting, blood-sucking dipteran (fly) encountered in sandy areas. In the United States, sandfly may refer to certain horse flies that are also known as "greenheads", or to members of the family Ceratopogonidae. Outside the United States, sandfly may refer to members of the subfamily Phlebotominae within the Psychodidae. Biting midges (Ceratopogonidae) are sometimes called sandflies or no-see-ums. New Zealand sandflies are in the genus Austrosimulium, a type of black fly.
Lutzomyia is a genus of phlebotomine sand flies consisting of nearly 400 species, at least 33 of which have medical importance as vectors of human disease. Species of the genus Lutzomyia are found only in the New World, distributed in southern areas of the Nearctic and throughout the Neotropical realm. Lutzomyia is one of the two genera of the subfamily Phlebotominae to transmit the Leishmania parasite, with the other being Phlebotomus, found only in the Old World. Lutzomyia sand flies also serve as vectors for the bacterial Carrion's disease and a number of arboviruses.
Phlebotomus is a genus of "sand flies" in the Diptera family Psychodidae. In the past, they have sometimes been considered to belong in a separate family, Phlebotomidae, but this alternative classification has not gained wide acceptance.
Cutaneous leishmaniasis is the most common form of leishmaniasis affecting humans. It is a skin infection caused by a single-celled parasite that is transmitted by the bite of a phlebotomine sand fly. There are about twenty species of Leishmania that may cause cutaneous leishmaniasis.
Psychodidae, called drain flies, sink flies, filter flies, sewer flies, or sewer gnats is a family of true flies. Some genera have short, hairy bodies and wings giving them a "furry" moth-like appearance, hence one of their common names, moth flies. Members of the sub-family Phlebotominae which are hematophagous may be called sand flies in some countries, although this term is also used for other unrelated flies.
The Phlebotominae are a subfamily of the family Psychodidae. In several countries, their common name is sand fly; but that name is also applied to other flies known as sandflies. The Phlebotominae include many genera of blood-feeding (hematophagous) flies, including the primary vectors of leishmaniasis, bartonellosis and pappataci fever. In the New World, leishmaniasis is spread by sand flies in the genus Lutzomyia, which commonly live in caves, where their main hosts are bats. In the Old World, sand flies in the genus Phlebotomus spread leishmaniasis.
A canine vector-borne disease (CVBD) is one of "a group of globally distributed and rapidly spreading illnesses that are caused by a range of pathogens transmitted by arthropods including ticks, fleas, mosquitoes and phlebotomine sandflies." CVBDs are important in the fields of veterinary medicine, animal welfare, and public health. Some CVBDs are of zoonotic concern.
Leishmania major is a species of parasites found in the genus Leishmania, and is associated with the disease zoonotic cutaneous leishmaniasis. L. major is an intracellular pathogen which infects the macrophages and dendritic cells of the immune system. Though Leishmania species are found on every continent aside from Antarctica, Leishmania major is found only in the Eastern Hemisphere, specifically in Northern Africa, the Middle East, Northwestern China, and Northwestern India.
Pintomyia falcaorum is an extinct species of sandfly in the moth fly subfamily Phlebotominae. P. falcaorum is solely known from early Miocene Burdigalian stage Dominican amber deposits on the island of Hispaniola.
Metofluthrin is a pyrethroid used as an insect repellent. The vapors of metofluthrin are highly effective and capable of repelling up to 97% of mosquitoes in field tests. Metofluthrin is used in a variety of consumer products, called emanators, for indoor and outdoor use. These products produce a vapor that protects an individual or area. Effectiveness is reduced by air movement. Metofluthrin is neurotoxic, and is not meant to be applied directly to human skin.
Lutzomia anthrophora is a species of what is commonly known as the sandfly in the order Diptera and it is a common vector for Leishmaniasis mexicana.
Many species of flies of the two-winged type, Order Diptera, such as mosquitoes, horse-flies, blow-flies and warble-flies, cause direct parasitic disease to domestic animals, and transmit organisms that cause diseases. These infestations and infections cause distress to companion animals, and in livestock industry the financial costs of these diseases are high. These problems occur wherever domestic animals are reared. This article provides an overview of parasitic flies from a veterinary perspective, with emphasis on the disease-causing relationships between these flies and their host animals. The article is organized following the taxonomic hierarchy of these flies in the phylum Arthropoda, order Insecta. Families and genera of dipteran flies are emphasized rather than many individual species. Disease caused by the feeding activity of the flies is described here under parasitic disease. Disease caused by small pathogenic organisms that pass from the flies to domestic animals is described here under transmitted organisms; prominent examples are provided from the many species.
Evandromyia chacuensis is a species of sand fly first circumscribed in 2018 from specimens collected in Argentina. It is the 12th species currently described in the subgenus Barrettomyia.
Bezzia nobilis is a species of biting midges in the family Ceratopogonidae. It is widely considered one of the most common Bezzia species; it is found in Eurasian regions, all over the United States, Central America, and even into South American countries like Brazil. B. nobilis seem to prefer aquatic environments; they are commonly observed in stagnant water pools in Eurasia regions and marshes in the southern United States. Adults of this species are easily distinguished by their black and yellow striped legs. Pupae are recognized by their brown bodies, abdominal spines, and respiratory horns. B. nobilis larvae are distinguished by brown heads and white bodies. Little information is known on their life cycle or mating habits. B. nobilis is a predatory species. While some research suggests they mainly feed on larvae of other insect species, experiments suggest they prefer immobile, easy prey such as dead adult flies, bacteria, and protozoa.
Pintomyia nuneztovari is a phlebotomous sand fly in the subgenus Pifanomyia native to South America. It was named by the entomologist who first described the species in the scientific literature, Venezuelan entomologist Ignacio Ortíz, to honor the scientific contributions of Manuel Núñez Tovar.
Lutzomyia longipalpis is a species complex of sandfly belonging to the family Psychodidae. This species is primarily present in Central and South America, but has also appeared in Mexico. There have been reports of L. longipalpis as far south as Argentina, as they are found in a wide variety of ecological conditions. Both males and females feed on sugars from plants and aphids, but only adult females feed on the blood of other mammals. The species has recently begun appearing in urban areas throughout Brazil, and serves as a key vessel for the propagation of the parasite Leishmania infantum. The presence of these flies appears to be strongly correlated to the presence of domestic chickens in Latin America. The first major urban outbreak of the lethal Visceral leishmanias epidemic was detected in Teresina, Piauí State in the early 1980s following a massive planting of acacias.
Maria Cristina Ferro de Carrasquilla, Colombian microbiologist and Leishmaniasis researcher, who worked for more than forty years at the National Health Institute of Colombia. Most of her research was focused on sandflies, which are Leishmaniasis vectors, contributing with the description of three new species: Lutzomyia torvida., Lutzomyia falcata, and Lutzomyia tolimensis. Given her research contributions, a sandfly species was named after her: Lutzomyia ferroae. Ferro also worked with Venezuelan equine encephalitis virus and received the Emeritus Researcher award from the National Health Institute of Colombia in 2007
