Evaluation of extracts of Caryocar brasiliense (Caryocaraceae) for their insecticidal potential on Lutzomyia longipalpis (Diptera, Psychodidae), the main vector of visceral leishmaniasis in brazil.

Amanda de Oliveira Baracho, Yrllan Ribeiro Sincur

In Brazil, kala-azar or Visceral Leishmaniasis (VL) is a parasitic disease with a high degree of lethality, transmitted to humans mainly by sandflies belonging to the species Lutzomyia longipalpis. The search for alternative products for the elimination of this vector aims to minimize the impacts caused by the synthetic insecticides used by the control programs. Therefore, the insecticidal activity of Caryocar brasiliense plant extracts on Lutzomyia longipalpis was evaluated in this study. Methods: Hydroethanolic and cyclohexane extracts of leaves and bark were obtained at concentrations of 50, 100, 200 and 400 mg/mL. Thirty sand flies were exposed to the.... Read More
