Increasing the digital repository of DNA barcoding sequences of sand flies (Psychodidae: Phlebotominae) [PDF]

, 2019
Sand f ly identification is complex because it depends on the expertise of the taxonomist. The females show subtle morphological differences and the occurrence of the species complexes are usual in this taxon.

Colonisation resistance in the sand fly gut:Leishmania protects Lutzomyia longipalpis from bacterial infection [PDF]

, 2014
BACKGROUND: Phlebotomine sand flies transmit the haemoflagellate Leishmania, the causative agent of human leishmaniasis. The Leishmania promastigotes are confined to the gut lumen and are exposed to the gut microbiota within female sand flies.
