“…Therefore, the mature nymphs of Africocypha varicolor were more of sprawlers that lie in ambush or stalk their prey at the water bottom. This ecological positioning and behavior agreed with the report of Lee [14,31,32] that categorized dragonfly naiads into two categories: sprawlers (bottom dwellers) and climbers (submerged in vegetation). Although, the two categories can feed on the same prey relative to frequency and availability of such prey [1,33].…”

“…It dominates any land area where found and expels other plants easily. Also, a few literatures had reported the predatory ability of nymphs of dragonfly on fish fry and other small aquatic invertebrates [14,15] Clarias gariepinus is one of the topmost fishes under culture in Nigeria. It has a wide distribution in Africa and can be found in swamps, lakes, rivers and streams as a freshwater species [16].…”

The use of natural organic extract instead of synthetic chemicals in harvesting wild fish and eliminating unwanted aquatic biota is popular in Nigeria. This research, therefore, investigated the possibility of using the root extract of a common weed in southwestern Nigeria, named P. alliacea, in checkmating the predatory influence of nymphs of dragonfly which frequently attack fry of African mud catfish.Activity of extract was first assessed through a brine shrimp test in a 24 hr investigation before concentrations of 0.0 g/l, 0.22 g/l, 0.48 g/l, and 1.06 g/l were applied under laboratory conditions in plastic aquaria against the naiads. The 96 hr Lc 50 was 0.47 g/l obtained using probit analysis. The regression equation for the probit curve was y=3.173+3.5 (y=probit value, x=actual concentration and r=0.7=coefficient of correlation). An average of six fry and one fry were consumed by one dragonfly nymph every 96 hr at two weeks and three weeks old, respectively.

“…Due to the feeding mechanism (piercer-suckers; Merritt & Cummins, 1996), the gut contents of hemipterans could not be analyzed, but are considered as carnivores based on the Merritt & Cummins (1996) and Bay (1974) descriptions.…”

The diet and trophic groups of an assemblage of aquatic insects were studied in a tropical stream. Genera of the orders Ephemeroptera, Odonata, Plecoptera, Lepidoptera, and Hemiptera showed feeding specialization. Others, such as Trichoptera, Coleoptera, and Diptera, showed great diet variation with genera of different trophic groups. Seasonal variation of insect diet, evident only for some genera of the orders Trichoptera, Lepidoptera, Coleoptera, and Diptera, was due to the differences observed in community composition and to generalist habits of these genera. However, the seasonal comparison of trophic groups showed no significant statistical differences. The great importance of organic matter, a non-limited resource, in the diet of Ribeirão do Atalho aquatic insects may be the explanation for the trophic stability in this community organization.Key words: aquatic insects, diet, trophic groups, tropical stream. RESUMO Dieta e grupos tróficos de uma comunidade de insetos aquáticos em um riacho tropicalA dieta e o grupo trófico de uma assembléia de insetos aquáticos foi estudada em um riacho tropical. Os gêneros de algumas ordens de insetos, como Lepidoptera, Ephemeroptera, Plecoptera, Odonata e Hemiptera, apresentaram especialização alimentar. Por outro lado, as ordens Trichoptera, Coleoptera e Diptera mostraram grande variação na dieta, com gêneros de diferentes grupos tróficos. Alguns gêneros das ordens Trichoptera, Lepidoptera, Coleoptera e Diptera apresentaram variação sazonal na dieta relacionada a mudanças na composição da comunidade e à dieta generalista desses gêneros. Entretanto, a comparação sazonal de grupos tróficos mostrou diferenças não significativas estatisticamente. A grande importância da matéria orgânica, um recurso não limitado, na dieta dos insetos aquáticos no Ribeirão do Atalho pode ser a explicação para a estabilidade da organização trófica dessa comunidade.Palavras-chave: insetos aquáticos, dieta, grupos tróficos, riacho tropical.

“…They should have more cryptic habits and be less active. These species, mainly those who live buried in the sediment or in detritus, use predominantly tactile mechanisms for prey detection (Bay, 1974;Corbet, 1999). This strategy probably restricts the quantity of perceptible prey, but also reduces the susceptibility to predation.…”

In the lakes of the Middle Rio Doce, Minas Gerais (MG), two groups of larval Libellulidae are distinguished by preferences of habitat use: one uses mainly aquatic macrophytes and the other uses the bottom substrate. The goal of this work was to verify if there is a morphological distinction between the two groups of species. Thirteen body measures were taken from the larvae and analyzed. No difference was found between the two groups of species regarding the body size, but shape differences were observed for two morphological variables. The species that use mainly macrophytes tend to have larger relative measures of the labium and smaller measures of the abdomen width. Advantages in resource obtainment and in vulnerability to predation are probably the explanations for the morphological divergence among these larval groups.Keywords: Ecomorphology, Libellulidae, macrophyte, Rio Doce. Ecomorfologia larval de 13 Libellulidae (Anisoptera, Odonata) do Vale do Médio Rio Doce, MG, Brasil ResumoNos lagos do Médio Rio Doce (MG), dois grupos de larvas de Libellulidae apresentam diferenças no uso do habitat: um utiliza preferencialmente macrófitas aquáticas e o outro utiliza a superfície do fundo. O objetivo deste trabalho foi verificar se existe uma distinção morfológica entre estes dois grupos. Treze medidas morfológicas foram tiradas das larvas e analisadas. Nenhuma diferença, com relação ao tamanho corporal, foi encontrada entre os dois grupos, embora diferenças de forma tenham sido observadas com relação a duas variáveis morfológicas. As espécies que usam principalmente macrófitas tendem a possuir maiores medidas relativas do lábio e menores medidas da largura do abdome, o oposto ocorrendo com as larvas habitantes do fundo. Vantagens na captura de presas e na vulnerabilidade à predação são provavelmente as explicações para a divergência morfológica observada entre os dois grupos de larvas.Palavras-chave: Ecomorfologia, Libellulidae, macrófitas, Rio Doce.
