Leishmaniasis is a vector borne disease caused by an intramacrophage protozoa, Leishmania (Order: Kinetoplastidae, Family: Trypanosomatidae, Genus: Leishmania), that is generally transmitted by sandflies, either Phlebotomus (Old world) or Lutzomyia
longipalpis [Psychodidae] (Spiegel et al.
1999) showed that both Lutzomyia
intermedia and Lutzomyia
whitmani phlebotomine flies are attracted to light.
shannoni (Dyar) is one of the more thoroughly studied species of the phlebotomine sand flies in North America (Figure 1).
Infection is indirect in that it is transmitted by numerous species of insects of the genera Phlebotomus and Lutzomyia
Researchers at Harvard Medical School and the Harvard School of Public Health in Boston report that the tropical sandfly, Lutzomyia
longipalpis, which transmits through its bite a parasitic disease, has a component in its saliva that boosts the virulence of the parasites it injects into its mammalian victims.
