“…Considering these changes, the nocturnal period showed more intense activity, when the peaks of greatest frequency presented in bimodal and trimodal forms. For Anopheles galvaoi, temporal activity underwent strong alteration with the dam formation; though the tendency observed was single peaks from 6 pm to 8 pm and from 4 am to 6 am, both related to twilight and dawn 24 . In the scenario created by the construction of the Porto Primavera Hydro-Power Station different levels of environmental changes were associated with differentiated impact on temporal activity, as a result of alterations in Anopheles diversity.…”

INTRODUCTION: Study of the temporal activity of malaria vectors during the implantation of a hydroelectric power station on the River Paraná, intended to generate electrical energy. The river separates the States of São Paulo and Mato Grosso do Sul, in Brazil. The objective was to verify whether alterations occurred in the wealth and diversity indices of Anopheles, following two successive floods, extended to the temporal activity and nycthemeral rhythm followed over a five year period. METHODS: Mosquito capture was performed monthly using the Human Attraction Technique and Shannon Traps. The first, executed for 24h, provided the nycthemeral rhythm and the second, lasting 15h, permitted the tracking of Anopheles during the two floods. RESULTS: The bimodal pattern of Anopheles darlingi defined before these floods was modified throughout the environment interventions. The same effect had repercussions on the populations of An albitarsis s.l., An triannulatus and An galvaoi. Activity prior to twilight was less affected by the environment alterations. CONCLUSIONS: The dam construction provoked changes in Anopheles temporal activity patterns, permitting classification of the area as an ecologically steady and unstable situation. Differences observed in Anopheles behavior due to the capture methods revealed the influence of solo and multiple attractiveness inside the populations studied.

“…The impacts caused by Culicid fauna should be reevaluated based on, among other reasons, environmental changes due to recent expansion of the hydropower sector in Brazil. Our example, among others, of negative impacts of large hydropower projects demonstrates the need for development of programs for the surveillance and control of vector fauna (GuimarãeS et al 1997). …”

Abstract. Three specimens of Anopheles darlingi Root were found in the Volta Grande environmental reserve, an area influenced by the Rio Grande dam constructed by the Volta Grande hydroelectric plant in Conceição das Alagoas, Minas Gerais, Brazil. The mosquito An. darlingi is one of the main vectors of human malaria in Brazil due to feeding preference for human blood, a factor that is accentuated by endophilic behavior. The information recorded here may be helpful to local entomological surveillance toward monitoring impacts generated by hydroelectric reservoir formation, as the presence of this vector in this type of environment indicates a potential risk for malaria transmission.Keywords: Hydropower; Malaria; Monitoring; Mosquitoes; Vectors. Primeiro registro de Anopheles darlingi Root (Diptera, Culicidae) na Região do Reservatório de Volta Grande, Conceição das Alagoas, Minas Gerais, BrasilResumo. Três espécimes de Anopheles darlingi Root foram encontrados na reserva ambiental Volta Grande, na área de influência da barragem do Rio Grande construída pela usina hidrelétrica de Volta Grande, em Conceição das Alagoas, Minas Gerais, Brasil. O mosquito An. darlingi é um dos principais vetores da malária humana no Brasil, devido à sua preferência alimentar por sangue humano, um fator que é acentuado pelo comportamento endofílico da espécie. O presente relato poderá ser útil à vigilância entomológica local para monitoramento dos impactos gerados pela formação do reservatório hidrelétrico, uma vez que a presença deste vetor neste tipo de ambiente indica um risco potencial de transmissão da malária.
