The insect vectors are species of sandfly of the genus Phlebotomus in the Old World, and of Lutzomyia in the New World. Sandflies are tiny flies, measuring 3–6 mm long by 1.5–3 mm in diameter, and are found in tropical or temperate regions throughout the world. The sandfly species Lutzomyia longipalpis is the primary vector of this disease ...
Austrosimulium australense, known as the New Zealand black fly or more commonly sandfly (namu in Māori), is a species of small fly of the family Simuliidae, endemic to New Zealand. Females consume blood for nutrients to produce eggs, and it is one of three species of Austrosimulium in New Zealand that often bite humans.

Leishmaniasis is a wide array of clinical manifestations caused by protozoal parasites of the Trypanosomatida genus Leishmania. [7] It is generally spread through the bite of phlebotomine sandflies, Phlebotomus and Lutzomyia, and occurs most frequently in the tropics and sub-tropics of Africa, Asia, the Americas, and southern Europe.
The direct bite of an infected sandfly during blood feeding allows for the parasitic transmission of Visceral leishmaniasis from L. longipalpis to the vertebrate host. The sandfly saliva contains potent physiological compounds that cause anticoagulant , vasodilating , and anti-inflammatory activity, which influences the immune response of the ...
The female sand fly carries the Leishmania protozoa from infected animals after feeding, thus transmitting the disease, while the male feeds on plant nectar. [ citation needed ] The parasite Leishmania donovani is the main causative agent of visceral leishmaniasis (VL) in India, Nepal, and Bangladesh, where it is transmitted by the sand flies ...
Laboratory colonies of various phlebotomine sand fly species have been established for experimental study. [ 4 ] A 2018 study showed that several sandfly species in different parts of the world displayed a notable preference for Cannabis sativa as part of their plant-derived diet, suggesting it might be highly attractive to them.
Austrosimulium ungulatum, known by the common name West Coast black fly or just sandfly, is a species of small fly of the family Simuliidae that is endemic to New Zealand. [1] Females consume blood for nutrients to produce eggs and it is one of three species of Austrosimulium in New Zealand that often bite humans.
