Avaliação ecológica rápida da fauna de vespas (Hymenoptera: Aculeata) do Parque Nacional da Serra do Divisor, Acre, Brasil

Abstract

RESUMOO Parque nacional da Serra do Divisor (PnSD), localizado a noroeste do Estado do Acre, é considerado uma das áreas de maior diversidade da Amazônia. A importância de se considerar insetos em programas de conservação tem sido muito enfatizada. vespas solitárias e sociais são componentes muito importantes dos ecossistemas, devido à posição que ocupam nas redes alimentares. Esse trabalho teve como objetivo realizar uma avaliação ecológica rápida da fauna de vespas do PnSD, para subsidiar a elaboração de um plano de manejo do referido parque. A amostragem foi realizada em 12 sítios de coleta, situados no interior de oito tipologias de vegetação. Os insetos foram coletados através de armadilhas Malaise, as quais foram expostas em todos os sítios por 24 horas, totalizando 288 horas de amostragem. Foram consideradas nas análises vespas das famílias Chalcididae, Eucharitidae, Evaniidae, Mutillidae, Pompilidae, Crabronidae e vespidae. Ao todo, foram coletados 366 indivíduos distribuídos em 40 gêneros e 85 espécies. Os gêneros Ephuta (Mutillidae), Trypoxylon (Crabronidae) e Conura (Chalcididae) foram os mais ricos em espécies. Os sítios localizados na região norte do PnSD, considerada zona intangível e zona primitiva, foram os mais ricos em espécies. Cerca de 65% das espécies foram exclusivas a um único sítio, o que significa que as amostras possuem pequena similaridade faunística. Algumas espécies coletadas são consideradas raras.PALAVRAS-CHAVE: vespas, Hymenoptera, Acre, Diversidade, Parque nacional da Serra do Divisor.Rapid ecological assessment of wasp fauna (Hymenoptera: Aculeata) of the Serra do Divisor National Park, Acre, Brazil ABSTRACTThe Serra do Divisor national Park (PnSD), located at the northwest of Acre State, Amazonia, is considered an area of great biodiversity. The question of considering insects in conservation programs. Solitary and social wasps are important components of the terrestrial ecosystems due to their position in trophic webs. The present study aimed at making a rapid ecological assessment of the wasps from the PnSD in order to support the elaboration of a conservation and management plan for that park. The insects were sampled in 12 sites located in eight forest types by Malaise traps that operated in each for 24 hours, totaling 288 hours of sampling. The results on the families Chalcididae, Eucharitidae, Evaniidae, Mutillidae, Pompilidae, Crabronidae and vespidae are presented here. On the whole, 366 wasps were collected representing 40 genera and 85 species. The genera Ephuta (Mutillidae), Trypoxylon (Crabronidae) and Conura (Chalcididae) were the most specious. The sites situated at the northern region of the PnSD, the intangible and primitive zones, were the most species rich. Some collected species were considered rare and about 65% of species were exclusive to only one site. This means that the samples have little faunal similarity.

The social wasp community (Hymenoptera, Vespidae) in an area of Atlantic Forest, Ubatuba, Brazil

“…centralis and Angiopolybia pallens were not collected in other studies, with the latter having been observed in another area of Atlantic Forest in Bahia (Santos et al 2007). These three species are more common in the inventories of the North and Northeast regions of Brazil, generally covered by "cerrado" and Amazonian rainforests (Silveira 2002;Melo et al 2005;Silveira et al 2005;Santos et al 2007;Morato et al 2008;Silveira et al 2008).…”

The Social Wasp Fauna of a Riparian Forest in Southeastern Brazil (Hymenoptera, Vespidae)

“…Other studies have also noted the predominance of Epiponini in the total abundance of social wasps found. Representatives of this tribe constituted more than 70% in many studies conducted in Brazil (Santos, 1996;Mechi, 2005 -Campos et al, 2007;Morato et al, 2008;Santos et al, 2009b;Silva & Silveira, 2009;Auad et al, 2010;Alvarenga et al, 2010;Lima et al, 2010;Pereira & Antonialli-Junior, 2011;Tanaka Junior & Noll, 2011;Simões et al, 2012;Grandinete & Noll, 2013;Togni et al, 2014). However, when only nests are the targets of surveys, the abundance of Epiponini is often smaller, as observed in Juiz de Fora, Minas Gerais (Lima et al, 2000), with only 11.03% of the colonies belonging to this tribe and in Biritinga, Bahia, were 67.43% of the total abundance found was of Epiponini, yet only 25.71% of the nests found belonged to this tribe (Santos & Presley, 2010).…”

“…group of insects, researches related to diversity of social wasps in this country are increasing in number and have covered different regions, environments and biomes (Richards, 1978;Rodrigues & Machado, 1982;Marques, 1989;Marques et al, 1993;Diniz & Kitayama, 1994;Mechi, 1996;Santos, 1996;Lima et al, 2000;Raw, 2003;Marques et al, 2005;Mechi, 2005;Melo et al, 2005;Hermes & Köhler, 2006;Santos et al, 2006;Silva-Pereira & Santos, 2006;Souza & Prezoto, 2006;Elpino-Campos et al, 2007;Santos et al, 2007;Morato et al, 2008;Ribeiro Junior, 2008;Silveira et al, 2008;Souza et al, 2008;Santos et al, 2009a;Santos et al, 2009b;Alvarenga et al, 2010;Auad et al, 2010;Lima et al, 2010;Santos & Presley, 2010;Souza et al, 2010;Pereira & Antonialli-Junior, 2011;Silva et al 2011;Souza et al, 2011;Tanaka Junior & Noll, 2011;Jacques et al, 2012;Silveira et al, 2012;Simões et al, 2012 ;Auko & Silvestre, 2013;Grandinete & Noll, 2013;Togni et al 2014).

Updating the geographic records of social wasps (Vespidae: Polistinae) in Roraima state

“…Recently, some studies have been carried out in the Brazilian Amazon in Acre State (Morato et al, 2008), Amapá State , Amazonas State , Somavilla et al, 2015Somavilla & de Oliveira, 2017), Maranhão State , Pará State (Silveira, 2002;Silva & Silveira, 2009) and Roraima State (Raw, 1998). Despite the constant effort in studies about social wasps conducted in Brazil, little is known regarding their diversity and distribution in the Amazon region.…”
