Sri Lanka. Phlebotomine sand flies Psychodidae: Diptera of Sri Lanka: a review on diversity, biology and bionomics. Phlebotomine sand flies are medically important insects widespread throughout the world and responsible for the transmission of several diseases to humans and other animals including leishmaniasis and sand fly fever. In Sri Lanka, a total of 22 species of sand flies belonging to two genera, namely: Phlebotomus and Sergentomyia, have been recorded with 6 and 16 species, respectively. The current study reports a complete list of the species of sand flies reported from Sri Lanka with a review on global and local distribution, biology and bionomics of each species as per published literature up to June

Sand flies are responsible for the transmission of leishmaniasis, a neglected tropical disease claiming more than 50, lives annually. Leishmaniasis is an emerging health risk in tropical and Mediterranean countries as well as temperate regions in North America and Europe. There is an increasing demand for predicting population dynamics and spreading of sand flies to support management and control, yet phenotypic diversity and complex environmental dependence hamper model development.

Leishmania pp Cite as. Of approximately species or subspecies of phlebotomine sand flies, 80 are proven or probable vectors of the 22 species of Leishmania that cause human disease Tables 1 and 2. In some foci of leishmaniasis, the vectors are unknown and it is certain that more species will be added to the list. This is a constraint in devising means of controlling the vectors and thus reducing the risk of infection. Most importantly, so little is known about the terrestrial breeding sites of sand flies that any attempt to control them by attacking the peri-marginal stages is impractical.

Phlebotomine Sand Flies: Biology and Control

Sand flies are the insects responsible for transmitting Leishmania parasites, the causative agents of leishmaniasis in humans. However, the effects of sand fly breeding sites on their biology and ecology remain poorly understood. Herein, we studied how larval nutrition associated with putative breeding sites of the sand fly Lutzomyia longipalpis affects their oviposition, development, microbiome, and susceptibility to Leishmania by rearing L. The results showed that female L. Typical gut microbial profiles were found in larvae reared upon cashew leaf litter.

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.

Control of phlebotomine Diptera: Psychodidae leishmaniasis vectors. Phlebotomines are of medical and veterinary concern as they vector leishmaniasis, bartonellosis and some arboviruses. The adaptations of some species to places modified by humans bring these vectors into contact with dwellings, which can facilitate disease transmission, and the vector control strategies adopted have rendered controversial results. Regarding leishmaniasis, for instance, which vector and reservoirs control can be effective, there is an assumption that the incidence of human infection is directly related to the number of infectious dogs, as well as to entomological factors. Therefore, vector control can provide a cheaper and more practical solution to prevent cases of leishmaniasis.
