Abstract
OBJETIVO: Avaliar a influência da velocidade do vento sobre o comportamento da população de Anopheles marajoara e sua paridade. MÉTODOS: As capturas foram feitas a cada dois meses, de janeiro de 1999 a fevereiro de 2000, no município de Ilha Comprida, no Estado de São Paulo, com utilização de aspirador manual movido à pilha. Utilizou-se o teste de Mann-Whitney para verificar a possível influência do vento sobre o comportamento dos mosquitos capturados. Para determinar a paridade, utilizou-se a técnica de Polovodova e a análise do desenvolvimento folicular de Christopher e Mer. RESULTADOS: Foram capturados 11.833 mosquitos, dos quais 3.072 foram de An. marajoara. Observou-se pico de atividade hematofágica de An. marajoara no período das 2:00 às 5:00h. Das 1.006 fêmeas dissecadas, 530 (52,7%) foram nulíparas, 432 (42,9%) uníparas, 24 (2,4%) bíparas e uma multípara; 982 (97,6%) apresentavam seus folículos nas fases I/II de Christopher e Mer, sete nas fases III/IV, e 17 na fase V. Verificou-se diferença significativa entre a freqüência de An. marajoara diante de vento com velocidades iguais ou superiores a 3 km/h e para medidas inferiores a 3 km/h. CONCLUSÕES: An. marajoara apresentou atividade hematofágica notadamente noturna. Verificou-se que aproximadamente 50% das fêmeas de An. marajoara dissecadas eram oníparas. O dado, associado à elevada porcentagem (97,6%) de fêmeas com folículos nos estágios I e II de Christopher e Mer, sugere a existência de concordância gonotrófica. A freqüência de An. marajoara sofreu considerável redução diante de ventos com velocidade igual ou superior a 3 km/h.
OBJECTIVE: To evaluate the impact of wind velocity on the behavior of An. marajoara population and its parity. METHODS: Collections were made bimonthly from January 1999 to February 2000 in the municipality of Ilha Comprida, Brazil. Adult mosquitoes were captured with a battery hand aspirator. Mann-Whitney test was applied to verify the wind impact on mosquito behavior. Polovodova technique and Christophers and Mer's follicular development analysis were used to determine parity. RESULTS: A total of 11,833 mosquitoes were captured, including 3,072 An. marajoara specimens. The peak of activity of An. marajoara occurred from 2 to 5 AM. Amongst 1,006 An. marajoara females who had their ovarioles dissected, it was found 530 (52.7%) nulliparous, 432 (42.9%) uniparous, 24 (2.4%) biparous and 1 multiparous. According to Christophers and Mer analysis, 982 (97.6%) had their follicles in phases I and II, 7 in phases III and IV, and 17 in phase V. The frequency of An. marajoara was significantly lower when wind velocity was 3 km/h or more or below 3 km/h. CONCLUSIONS: An. marajoara mosquitoes were more active at night. About 50% of dissected An. marajoara females were oniparous. Another important finding was the high proportion of females (97.6%) with follicles in the Christophers and Mer's phases I and II, suggesting the presence of gonotrophic concordance. Wind velocity equal or higher than 3 km/h considerably reduced the frequency of An. marajoara.
