Vector competence of Culex quinquefasciatus say from different regions of Brazil to Dirofilaria immitis

Abstract

The vector competence of Culex quinquefasciatus from five localities in Brazil to

Vector competence of Culex quinquefasciatus Say, 1823 exposed to different densities of microfilariae of Dirofilaria immitis (Leidy, 1856)

“…quinquefasciatus RECIFE population was similar at all microfilaria densities, which is in agreement with data obtained by Ahid et al (2000) for Cx. quinquefasciatus and is also similar to results obtained by Taylor (1960) and Mendonça et al (1998) for Ae.…”

“…Dead mosquitoes were dissected and examined for D. immitis larvae daily. The infection ratio (IR) was calculated according to procedures described by Ahid et al (2000) and the vector efficiency index (VEI) was determined according to the procedures described by Kartman (1954).…”

“…Biology; experimental infections; mosquitoes. Rio de Janeiro, (Lourenço-De-Oliveira & Deane 1995;Labarthe et al 1998 a,b), Alagoas (Brito et al 1999) and Maranhão Ahid et al 2000). In the Brazilian Northeast Region, the species Cx.…”

Low genetic diversity in Wolbachia-Infected Culex quinquefasciatus (Diptera: Culicidae) from Brazil and Argentina

“…Culex quinquefasciatus populations have been significantly impacted by control programs in Brazil, particularly in northern and northeastern equatorial regions, where the species is the primary vector of lymphatic filariasis and dirofilariasis 1 . The regions' low altitude, hot and humid climate and constant thermal amplitude facilitate both the development of the heartworm pathogen and the hematophagy of Culex vectors throughout the year 25 .…”

Vectorial competence of Aedes aegypti (Linnaeus 1762) Rio de Janeiro Strain, to Dirofilaria immitis (Leidy 1856)

“…scapularis (Rondani 1848) has been made evident by Macêdo et al (1998). Vector competente of Culex quinquesfasciatus (Say) from different regions of Brazil to D. immitis was studied by Ahid et al (2000). Ae.…”
