Combining epidemiology with basic biology of sand flies, parasites, and hosts to inform leishmaniasis transmission dynamics and control. [PDF]

, 2017
Quantitation of the nonlinear heterogeneities in Leishmania parasites, sand fly vectors, and mammalian host relationships provides insights to better understand leishmanial transmission epidemiology towards improving its control. The parasite manipulates

Ecological determinants of leishmaniasis vector, Lutzomyia spp.: A scoping review

Medical and Veterinary Entomology, Volume 38, Issue 4, Page 393-406, December 2024.
Lutzomyia spp. survival is impacted by climatic, habitat and geodemographic factors. Lutzomyia spp. have demonstrated a wide range of temperature tolerance, ranging from 11 to 30°C. There is limited research on this topic, posing a significant challenge for future studies. Abstract Leishmania spp. are zoonotic parasites transmitted by phlebotomine sand

The Transcriptome of Lutzomyia longipalpis (Diptera: Psychodidae) Male Reproductive Organs

PLoS ONE, 2012
It has been suggested that genes involved in the reproductive biology of insect disease vectors are potential targets for future alternative methods of control. Little is known about the molecular biology of reproduction in phlebotomine sand flies and there is no information available concerning genes that are expressed in male reproductive organs of ...

The complexities of blood‐feeding patterns in mosquitoes and sandflies and the burden of disease: A minireview

Veterinary Medicine and Science, Volume 10, Issue 5, September 2024.
Mosquitoes and phlebotomine sandflies are infectious disease vectors through hematophagy. The development of hematophagy likely provided an evolutionary advantage, offering a rich nutrient source for reproduction. These insects exhibit diverse blood‐feeding patterns, from invertebrates to various vertebrates. Multiple sensory cues to guide host‐seeking

Fatty acids derived from oviposition systems guide female black soldier flies (Hermetia illucens) toward egg deposition sites

Insect Science, Volume 31, Issue 4, Page 1231-1248, August 2024.
While the polyphagous larvae of the black soldier fly (Hermetia illucens) are gaining interest as an alternative protein source for food and feed, little research has been done on the behavior of the adults. We identified three fatty acids and one fatty acid methyl ester derived from old oviposition sites and aimed to elucidate their effect on ...

Geoclimatic drivers of diversification in the largest arid and semi‐arid environment of the Neotropics: Perspectives from phylogeography

Molecular Ecology, Volume 33, Issue 14, July 2024.
Abstract The South American Dry Diagonal, also called the Diagonal of Open Formations, is a large region of seasonally dry vegetation extending from northeastern Brazil to northern Argentina, comprising the Caatinga, Cerrado, and Chaco subregions. A growing body of phylogeography literature has determined that a complex history of climatic changes ...

Bionomic aspects of Lutzomyia evansi and Lutzomyia longipalpis, proven vectors of Leishmania infantum in an endemic area of non-ulcerative cutaneous leishmaniasis in Honduras

Parasites & Vectors, 2018
Background Some Lutzomyia species are the vectors of human leishmaniasis in the Americas. Visceral and cutaneous leishmaniasis are both endemic in the Pacific region of Honduras, but the non-ulcerative form is the more frequent clinical manifestation in ...
