Resumo: | OBJECTIVE: Anopheles bellator e An. cruzii are vectors of the so-called bromeliad-malaria, typical of conserved areas. The objective was to evaluate the seasonal and vertical distribution of these anophelines, aiming at assessing the risk of malaria transmission. METHODS: In the municipality of Ilha Comprida, Southeastern Brazil, CDC light traps baited with dry ice were placed fortnightly from 17:00 to 20:00, at one, six and 12 meters high from September 2001 to September 2002. Association between An. bellator and An. cruzii densities and weather were assessed by Spearman coefficient and comparisons among heights and species densities were made by Mann-Whitney non-parametric test. RESULTS: A total of 55,226 mosquitoes were caught: 1,341 were An. bellator (2.4% of Culicidae), 278 at one meter, 261 at six meter and 802 at 12m high. Following the same sequence, An. cruzii was represented by 452, 1,032 and 4,420 adults, totalizing 5,904 mosquitoes (10.7%). There was a positive correlation between densities of both species and daily maximum temperature, and between density of An. bellator and thermal amplitude. The densities were higher for both species at tree canopy. At the three levels, the density of An. cruzii was higher. CONCLUSIONS: The acrodendrophilic behavior of these species was confirmed, remarkably in An. cruzii. After aggressive measures of control, these anophelines have remained in this region, but they are not under entomological surveillance. The persistent transmission of malaria and increasing tourism activities in this region highlight the need for surveillance of these species. |

OBJETIVO: Anopheles bellator e An. cruzii são vetores da malária-bromélia, característicos de áreas preservadas. O objetivo do estudo foi analisar a distribuição sazonal e vertical desses anofelinos, visando contribuir para a avaliação do risco de transmissão desse agravo. MÉTODOS: No município de Ilha Comprida, SP, foram instaladas armadilhas luminosas tipo CDC iscadas com gelo seco, das 17 às 20h, a um, seis e 12m do solo, quinzenalmente, de setembro de 2001 a setembro de 2002. A relação da densidade desses anofelinos com o clima foi avaliada pelo coeficiente de Spearman e suas densidades entre os estratos foram comparadas pelo teste não paramétrico de Mann-Whitney. RESULTADOS: Do total de 55.226 mosquitos, 1.341 eram An. bellator (2,4% do total de Culicidae), sendo capturados 278 indivíduos próximo ao solo, 261 a seis metros e 802 na copa (12 m). Na mesma ordem, foram capturados 452, 1.032 e 4.420 adultos de An. cruzii, totalizando 5.904 mosquitos desta espécie (10,7%). Houve correlação positiva entre a densidade das duas espécies com a temperatura máxima, e entre An. bellator e amplitude térmica diária. As densidades das duas espécies foram maiores na copa. Nos três estratos, An. cruzii predominou sobre An. bellator. CONCLUSÕES: Confirmou-se o comportamento acrodendrófilo dessas espécies, principalmente An. cruzii. Após medidas drásticas de controle, esses anofelinos permaneceram na região mas, atualmente, não são alvo de vigilância entomológica. A persistência da transmissão de malária autóctone e o incremento de atividades de ecoturismo na região apontam a necessidade de monitoramento dessas espécies. Universidade de São Paulo.
