Description
Summary:A study on the ecology of phlebotomine sandfly fauna in a restricted focus of cutaneous leishmaniasis in northern Venezuela was undertaken in order to investigate the species responsible for the transmission. The study area and catching methods for phlebotomine sandflies are described. A total of 9,061 females and 1,662 males were collected during a year-term study. 12 species of Lutzomya and 1 species of Brumptomya sp. were identified. Absolute and relative abundance and ocurrence for each species were determined. The rel ative occurrence allowed to distinguish the common species, viz. L. panamensis, L. ovallesi, L. gomezi, L. tinidadensis, L. atroclavata, L. cayennensis, L. shannoni and L. olmeca bicolor from the rare species vis., L. punctigeniculata, L. rangeliana, L. evansi and L. dubitans. General comments on the species composition of the sandfly fauna in this locality are made.<br>Foi realizado um estudo da ecologia da fauna de flebotomíneos em um foco restrito de leishmaniose no norte da Venezuela, a fim de procurar determinar quais as espécies vetoras. São descritos os métodos de captura e a área estudada. Os totais de 9.061 fêmeas e 1.662 machos foram coletados durante um ano de estudo. Foram identificados doze espécies de Lutzomya e uma de Brumptomya, sendo determinados a ocorrência e a abundância absoluta e relativa de cada espécie. Foi possível distinguir as espécies comuns, como panamensis, L. ovallesi, L. gomezi, L. trinidadensis, L. atroclavata, L. cayennensis, L. shannoni e L. olmeca bicolor, das espécies raras, como L. punctigeniculata, L. rangeliana, L. evansi e L. dubitans. São feitos comentários gerais sobre a composição da fauna flebotômica da área de estudo.
