A laboratory evaluation of alcohols as attractants for the sandfly Lutzomyia longipalpis (Diptera:Psychodidae) [PDF]

Parasites & Vectors, 2014
The potential attraction from 1-octen-3-ol for sandflies has been documented; however, studies using other primary alcohols are limited.We used a wind tunnel to compare the activation and attractive behaviors in male and female Lutzomyia longipalpis using 1-octen-3-ol and three additional alcohols, 1-octanol, 1-heptanol and 1-nonanol at three different

The retained capacity of Lutzomya longipalpis (Lutz & Neiva) to transmit Leishmania chagasi (Cunha & Chagas) after eight years (64 generations in a closed laboratory colony

Memorias do Instituto Oswaldo Cruz, 1985
A closed Lutzomyia longipalpis colony, from Ceará has been used to transmit Leishmania chagasi isolated from a fox in Pará state. The last time this colony was successfully used in similar transmission experiments was eight years (64 generations) ago ...

Carbohydrate digestion in Lutzomyia longipalpis’ larvae (Diptera – Psychodidae)

Journal of Insect Physiology, 2012
Lutzomyia longipalpis is the principal species of phlebotomine incriminated as vector of Leishmania infantum, the etiological agent of visceral leishmaniasis in the Americas. Despite its importance as vector, almost nothing related to the larval biology, especially about its digestive system has been published. The objective of the present study was to

Factors Associated With the Emergence and Spread of Visceral Leishmaniasis in the State of São Paulo, Brazil

Zoonoses and Public Health, Volume 73, Issue 4, Page 348-357, June 2026.
ABSTRACT Introduction Visceral leishmaniasis (VL), once considered a rural disease in Brazil, has progressively urbanised, particularly in the state of São Paulo (SSP), where the first urban cases emerged after the detection of the vector Lutzomyia longipalpis in 1997.

The Regulatory Effect of Histone Deacetylase (HDAC) 1 and 2 on iNOS, IL‐6, TNF‐α and IL‐10 Expression in Canine Macrophages Infected With Leishmania infantum

Parasite Immunology, Volume 48, Issue 4, April 2026.
ABSTRACT Zoonotic visceral leishmaniasis is caused by Leishmania (Leishmania) infantum. Dogs are considered the most critical urban reservoirs of L. (L.) infantum due to their high infection rate and direct transmission to humans. The parasite has developed mechanisms to evade the host's defence system by inhibiting macrophage activation, thereby ...
