Biologia de anofelinos Amazônicos. XI. Estudos em populações de Anopheles e controle da malária em Ariquemes (Rondônia)

Abstract

RESUMO São apresentados dado , 1983; Tadei , 1986a).

Ecologic observations on anopheline vectors of malaria in the Brazilian Amazon.

“…Anopheles darlingi is the principal vector of malaria in Amazonia because it is highly anthropophilic. [23][24][25] Precipitin tests indicated a definite preference of this species for humans. 26 This species is able to maintain malarial endemicity even when densities are low.…”

“…From there, they could enter the houses, take a human blood meal, usually from the lower legs, and leave with little probability of coming into contact with residual insecticides. 25 A knowledge of the degree of exophilia and endophilia is necessary to determine the control strategy to be used. In Venezuela, for example, An.…”

“…In Amazonia, the anophelines demonstrate a pronounced exophilia and therefore control methods that only include intradomiciliary spraying and the treatment of infected people are insufficient to reduce the transmission rate of malaria. [23][24][25] It is important to inform local inhabitants as to the habits of anopheline mosquitoes.…”

Population genetic structure of the major malaria vector Anopheles darlingi (Diptera: Culicidae) from the Brazilian Amazon, using microsatellite markers

“…In addition, compared with 50 yr. ago (Deane et al 1948) some populations of An. darlingi have changed their behavior, now being more exophilic and exophagic and/or leaving dwellings immediately after feeding (Tadei 1987, Charlwood 1996, Gil et al 2003, making the use of indoor insecticide and other individual protection measures less effective. This complex situation suggests that integrated and coordinated local or regional control must be considered.…”

Variação da densidade anofélica com o uso de mosquiteiros impregnados com deltametrina em uma área endêmica de malária na Amazônia Brasileira

“…darlingi de uma área para outra (Charlwood & Hayes, 1978;Rosa-Freitas et al, 1992), no Brasil ele é freqüentemente exofágico (Charlwood & Hayes, 1978;Deane, 1986;Lourenço-de-Oliveira et al, 1989;Klein & Lima, 1990). Em Rondô-nia, tem sido bem registrada a antropofilia (Lourenço-de-Oliveira et al, 1989;Klein & Lima, 1990;Oliveira-Ferreira et al, 1992;Lourenço-de-Oliveira et al, 1996) e a exofilia deste vetor (Tadei, 1986;Lourenço-de-Oliveira et al, 1989;Oliveira-Ferreira et al, 1990;Klein & Lima, 1990;Lourenço-de-Oliveira et al, 1994). Embora em algumas localidades de Rondônia tenha sido verificado um comportamento unimodal da atividade de picar do An.…”
