“…According to Berg (1995), it is not unusual for this item to represent 50%-70% of the gut contents of chironomids. Nessimian & Sanseverino (1998) found detritus as the most abundant item in the diet of Chironominae and Orthocladiinae genera from the Paquequer River (Teresópolis, State of Rio de Janeiro), together with a high concentration of pollen and spores. In Rio da Fazenda, the most important items, after detritus, were leaf and wood fragments as well as fungi in the diet of the Chironominae and Orthocladiinae subfamilies, while animal remains were found in Tanypodinae.…”

“…Nessimian & Sanseverino (1998), studying the diet of chironomid larvae in a stream in the mountain region of the State of Rio de Janeiro, registered that the composition of the gut contents changed according to the type of microhabitat (e.g., type of substrate) where the larvae were found. Also, they observed differences among samples from the same microhabitats in different seasons, as a result of changes in the type of available substrate.…”

“…Engulfers usually attack and ingest the whole prey or its pieces, while piercers bore the prey tissues removing their body fluids (Berg, 1995). However, it is important to recognize that most chironomids are not restricted to a single feeding mode, as also pointed out by Nessimian & Sanseverino (1998) and Nessimian et al (1999).…”

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).Key words: food habits, gut contents, Chironomidae, larvae. RESUMOHábitos alimentares das larvas de Chironomidae (Insecta: Diptera) de um riacho na Floresta da Tijuca, Rio de Janeiro, BrasilAs 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).Palavras-chave: alimentação, conteúdo estomacal, Chironomidae, larva.

Chironomidae feeding habits in different habitats from a Neotropical floodplain: exploring patterns in aquatic food webs

et al. 2016

Ecological studies on food webs have considerably increased in recent decades, especially in aquatic communities. Because Chironomidae family are highly specious, occurring in almost all aquatic habitats is considered organisms-key to initiate studies on ecological relationships and trophic webs. We tested the hypothesis that the diversity of the morphospecies diet reflects differences on both the food items available among habitats and the preferences of larval feeding. We analyzed the gut content of the seven most abundant Chironomidae morphospecies of the different habitats from the Upper Paraná River. We categorized the food items found into algae, fungal spores, fragments of plants, algae and animal fragments and sponge spicules. We observed the algae predominance in the gut content of morphospecies from lakes. Considering the different regions from each lake, we registered the highest food abundance in the littoral regions in relation to the central regions. From the variety of feeding habits (number of item kinds), we classified Chironomus strenzkei, Tanytarsus sp.1, Procladius sp.1 as generalist morphospecies. We found a nested pattern between food items and Chironomidae morphospecies, where some items were common to all taxa (e.g., Bacillariophyceae algae, especially), while others were found in specific morphospecies (e.g., animals fragments found in Procladius sp.1). The algae represented the most percentage of gut contents of Chironomidae larvae. This was especially true for the individuals from littoral regions, which is probably due to the major densities of algae associated to macrophytes, which are abundant in these regions. Therefore, the feeding behavior of these morphospecies was generalist and not selective, depending only of the available resources.Keywords: lakes, food networks, aquatic invertebrate, food resources, Upper Paraná River.

“…The absence of Elmidae in February and April 2002 can be related to the heavy rainfall that concentrated days before collections of February (100 mm) and along March 2002 (252.1 mm). Rain can exert high influence on the aquatic fauna, washing out the substrate, causing organisms to drift, and altering habitat characteristics (Nessimian and Sanseverino 1998).…”

., SPIES, M.R., PIRES, M.M. Diversity and distribution of riffle beetle assemblages (Coleoptera, Elmidae) in montane rivers of Southern Brazil. Biota http://dx.doi.org/10.1590/1676-060320140615183046Abstract: The diversity and spatio-temporal distribution of Elmidae (Coleoptera) assemblages in montane rivers and streams of southernmost Brazil (Rio Grande do Sul state) were studied. Six genera were found, represented mostly by larval specimens. Austrolimnius and Macrelmis are new occurrences in the region. Assemblages' genera composition and dominance were related to the presence of the macrophyte Podostemum. Also, water temperature and stream depth and velocity were the most important drivers related to the assemblages' distribution. Richness and abundance were positively related to high water velocity and negatively to stream depth. Temporal patterns were detected especially in assemblage abundance, yet a slight pattern in richness was also observed. The seasonal structure was related to warm temperatures, but temporal distribution of Elmidae assemblages appears to be related to the dominant genera life cycles. The studied area shows an overall Elmidae richness similar to that found in some tropical areas and the role of mountainous environments in sustaining high rates of regional diversity in the Neotropics is stated. Keywords: aquatic insects, streams, Neotropical region.
