“…In these areas, and also in Minas Gerais, Brazil, females are commonly seen on the exterior walls of houses (Bustamante & Guedes 1950). Such behaviour has been reported for mosquitoes from areas where the inside walls of houses have been sprayed with DDT (Hayes & Charlwood 1977, Charlwood & Paraluppi 1978, Charlwood & Wilkes 1979, Charlwood 1980. In Surinam Rozendaal (1989) considered that, despite a limited period spent inside houses, indoor spraying with DDT would still provide effective control.…”

“…The propensity of mosquitoes to feed inside houses and to rest in them once they have done so may be independent adaptations. For example, Hayes & Charlwood () described how in Brazil Anopheles darlingi came into the open houses used on the newly opened Manaus–Caracari highway, fed and left when engorged without touching a single surface in the room other than the undersides of people's hammocks.…”

The relative efficacy of a mechanical (Prokopack) collection method vs. manual aspiration in the collection of resting mosquitoes was evaluated in northern Tanzania before and after an intervention using indoor residual spraying and longlasting insecticide-treated nets. In smoke-free houses mosquitoes were collected from the roof and walls, but in smoky houses mosquitoes were found predominantly on the walls. Anopheles gambiae (Diptera: Culicidae) constituted 97.7% of the 312 An. gambiae complex specimens identified before but only 19.3% of the 183 identified after the intervention. A single sampling with the Prokopack collected a third of the available insects. Anopheles gambiae completed its gonotrophic development indoors, whereas Anopheles arabiensis did so outdoors. In both species gonotrophic development took 2 days. Most unfed resting An. arabiensis collected outdoors were virgins, whereas the majority of engorged insects were parous (with well-contracted sacs). Daily survival was estimated to be 80.0%. Only 9.4% of the engorged An. arabiensis collected outdoors and 47.1% of those collected indoors had fed on humans. Using the Prokopack sampler is more efficient than manual methods for the collection of resting mosquitoes. Malaria transmission may have been affected by a change in vector composition resulting from a change in feeding, rather than reduced survival. Monitoring the proportions of members of the An. gambiae complex may provide signals of an impending breakdown in control.

“…Na Amazônia, há relatos de que o An. darlingi pode modificar o comportamento de endofíli-co para exofílico, de endofágico para exofágico e de antropofílico para zoofílico, provocado pela excito-repelência de inseticidas usados na borrifação domiciliar (Hayes & Charlwood, 1977;Charlwood & Hayes, 1978;Roberts et al, 1984;Lourenço-de-Oliveira et al, 1989;Oliveira-Ferreira et al, 1990).…”

Em 1992, foi realizado um ensaio de campo com mosquiteiros impregnados com deltametrina, em uma área endêmica de malária no Município de Costa Marques, Rondônia. No período de baixa transmissão, os mosquiteiros impregnados (MI) diminuíram a densidade vetorial no intradomicílio, de modo semelhante, porém, aos mosquiteiros não impregnados (NI) na maioria das avaliações-controle. Por outro lado, na época de alta transmissão, os MI provocaram diminuição significante da média horária de anofelinos capturados, ao passo que, nas casas com NI, verificou-se aumento do número de mosquitos capturados. No peridomicílio, em geral, não houve diferença do número de anofelinos capturados entre MI e NI. No grupo MI, a espécie mais capturada foi o An. darlingi (63,2%), mais freqüente no peridomicílio, seguida pelo An. deaneorum (35,3%), mais freqüente no intradomicílio. Os MI diminuíram a densidade vetorial no intradomicílio pelo efeito excito-repelente, sem diminuí-la, contudo, no peridomicílio.
