“…However, this difference is valid only for the streams analyzed (Assis et al 2004, Anjos-Santos & Costa 2006.

“…Besides, the occurrence of odonates has been documented in less than one-third of the Brazilian territory, and especially in areas with tropical and subtropical climates (De Marco Junior & Vianna 2005). Additionally, bioecological studies have focused mainly on lakes and floodplains (De Marco Junior & Latini 1998, Franco & Takeda 2002, Fulan & Henry 2006, 2007, Juen et al 2007, Giacomini & De Marco Junior 2008, while main channels of lowland rivers (Ferreira-Peruquetti & De Marco Junior 2002, Assis et al 2004), montane streams (Dalzochio et al 2011), wetlands (Maltchik et al 2010), reservoir and fishfarms (De Marco Junior et al 1999, Fonseca et al 2004) are poorly known.…”

Diversity of Odonata (Insecta) larvae in streams and farm ponds of a montane region in southern Brazil

et al. 2013

View full text Add to dashboard Cite

This study presents an inventory of the genera of Odonata found in streams and artificial farm ponds in a montane region, with temperate climate, in southern Brazil. Differences in richness of lotic and lentic environments were also investigated. The diversity of odonate families and genera in southernmost Brazil is lower than in warmer, either tropical or subtropical, regions of the country. Nine genera are new records for the region and six genera had their geographical ranges extended to regions with temperate climate of the Neotropics. The overall richness and especially the overall abundance recorded in the studied area are possibly determined by the occurrence of numerous farm ponds because natural standing waters are scarce in the region. The presence of macrophytes in these artificial ponds allowed the establishment of a diversified odonatofauna, typical of lentic environments. Resumo: Este estudo apresenta um inventário de gêneros de Odonata de riachos e reservatórios artificiais de uma região montanhosa de clima temperado no extremo sul do Brasil. Diferenças na riqueza de ambientes lóticos e lênticos também foram investigadas. A diversidade de famílias e gêneros de Odonata no extremo sul do Brasil é menor que em regiões mais quentes, tanto tropicais quanto subtropicais, do país. Nove gêneros são novos registros para a região e seis gêneros tiveram suas distribuições geográficas de ocorrência estendidas para áreas temperadas da região Neotropical. A riqueza e a abundância verificadas na área de estudo possivelmente foram determinadas pela ocorrência de numerosos reservatórios artificiais, pois áreas lênticas naturais são raras na região. A presença de macrófitas nestes reservatórios permitiu o estabelecimento de uma fauna de Odonata diversificada e típica de ambientes lênticos. Palavras-chave: libélulas, inventário, região Neotropical, reservatórios, fauna lótica.

Farm ponds help maintain diversity in altered landscapes. However, studies on the features that drive this type of property in the Neotropics are still lacking, especially for the insect fauna. We analyzed the spatial and temporal distribution of odonate larval assemblages in farm ponds. Odonates were sampled monthly at four farm ponds from March 2008 to February 2009 in a temperate montane region of southern Brazil. A small number of genera were frequent and accounted for most of the dominant fauna. The dominant genera composition differed among ponds. Local spatial drivers such as area, hydroperiod, and margin vegetation structure likely explain these results more than spatial predictors due to the small size of the study area. Circular analysis detected seasonal effect on assemblage abundance but not on richness. Seasonality in abundance was related to the life cycles of a few dominant genera. This result was explained by temperature and not rainfall due to the temperate climate of the region studied. The persistence of dominant genera and the sparse occurrence of many taxa over time probably led to a lack in a seasonal pattern in assemblage richness.

The presence of larvae of predator insects in fish farming ponds is one of the factors that contribute to the reduction of the survival of fingerlings and consequently to the decrease of production profits. Dragonflies, which belong to the order Odonata, lay their eggs directly in the water, are among the insects that have a harmful effect on fish farming. The larvae are aggressive carnivores and predate post-larvae fish and fingerlings, and thus become economically relevant plagues. The objective of this work is to study the occurrence of Odonata larvae in fish ponds and evaluate the effect of Melia azedarach extract adsorved in silica to control Odonata larvae predation on common carp. A total of 126 larvae (Insecta: Odonata) of the suborder Anisoptera were registered in the monitored ponds. Of those, 80 belonged to the family Aeshnidae and 46 to the Libellulidae. The genera Neuraeschna was dominant in the three sampled ponds and was used in the biological tests. During the predation tests of common carp fingerlings (Cyprinus carpio) by the Neuraeschna larva, the average consumption was of 5,2 and 7,2 fingerlings in the treatments with and without Cinamono Ethanolic extract (EEC), respectively. The adoption of good practises in Aquaculture and the sustainability of fish farming require the adoption of natural products.
