Studies on mosquitoes (Diptera: Culicidae) and anthropic environment. 12- Host-seeking behaviour of Anopheles albitarsis s.l. in South-Eastern Brazil

Abstract

Results obtained with Anopheles albitarsis s.l. catches mainly performed through human bait at the Ribeira Valley region, SP (Brazil), are reported. Two species of the complex were recognized, namely An. albitarsis s.s. and species B. This latter predominated both in the rice fields and in the dwelling environments. The crepuscular rhythms showed an unimodal sunset pattern with most blood-seeking females caught during dusk. The absence of differences between indoor and outdoor behavior was confirmed for both species of the complex. Anopheles. Ecology, vectors. Resumo

The Anopheles albitarsis complex with the recognition of Anopheles oryzalimnetes Wilkerson and Motoki, n. sp. and Anopheles janconnae Wilkerson and Sallum, n. sp. (Diptera: Culicidae)

“…Furtermore, An. oryzalimnetes n. sp showed unimodal sunset crepuscular rhythms (Forattini et al 1996). In another study carried out in the same region of the Ribeira Valley, Forattini et al (1995) observed a concentration of An.…”

Anopheles albitarsiss.l. (Diptera: Culicidae) Survivorship and Density in a Rice Irrigation Area of the State of São Paulo, Brazil

“…The mosquito density was estimated by human bait collection through captures of adult female anophelines with small hand-held aspirators, without allowing females mosquitoes to effectively bite Þeld staff. Collections began at sunset and continued for 2 h, because previous studies in the area showed that Ϸ90% of hematophagous activity occurred during this period (Forattini et al 1996). Two persons conducted collections for one night every 2 wk, from May 1996 until June 2000, totaling 108 nights.…”
