          Abstract

          Chironomids larvae are frequently one of the most abundant and diverse groups of insects in several kinds of aquatic environments. Also, they play a major role in the aquatic food webs, representing a major link among producers and secondary consumers. This work investigates the feeding behavior of the chironomid larvae present in the Rio da Fazenda, situated in the Parque Nacional da Tijuca, Rio de Janeiro, Brazil, between August 1994 and May 1995. Algae, fungi, pollen, leaf and wood fragments, animal remains, detritus and silt were the main gut contents found in the larvae studied. The main food item ingested by the larvae was detritus, except for the Stenochironomus whose main food source was leaf and wood fragments. Tanypodinae exhibited a large quantity of animal remains of several kinds in the diet. During the period studied it was observed that the diet of 16 genera (out of 24 studied) varied. Tanypodinae had mainly coarse particulate organic matter (> 1 mm) in the gut contents, while Chironominae and Orthocladiinae had fine particulate organic matter (< 1 mm).

          As larvas de Chironomidae são freqüentemente o grupo de insetos mais abundante e diversificado em vários tipos de ambientes aquáticos, apresentando importante papel nas redes tróficas das comunidades aquáticas, por constituírem efetiva ligação entre produtores e consumidores. Este trabalho analisou o comportamento alimentar das larvas de Chironomidae presentes no rio da Fazenda, localizado no Parque Nacional da Tijuca, Rio de Janeiro, Brasil, entre agosto de 1994 e maio de 1995. Os principais itens alimentares encontrados foram algas, fungos, pólen, fragmentos vegetais, restos animais, detritos e silte. O principal item alimentar ingerido pelas larvas foi detrito, exceto para Stenochironomus, cujo principal componente alimentar foram fragmentos vegetais. Os Tanypodinae também exibiram grande quantidade de restos animais de diversos grupos na dieta alimentar. Foi observada variação na dieta alimentar para 16 gêneros. Os Tanypodinae apresentaram principalmente matéria orgânica particulada grossa (> 1 mm) no conteúdo digestivo, enquanto os Chironominae e os Orthocladiinae apresentaram matéria orgânica particulada fina (< 1 mm).
