Perfil da fauna de himenópteros parasitóides (Insecta, Hymenoptera) em uma área de Mata Atlântica do Parque Estadual da Fonte Grande, Vitória, ES, Brasil

Abstract

ABSTRACT. Survey of the hymenopterous parasitoids (Insecta, Hymenoptera) from the Parque Estadual da Fonte Grande, Vitória, ES, Brazil. Parasitoids Hymenoptera were collected in a trail inside the Parque Estadual da Fonte Grande (20º17'51.7''S; 40º20'13.1''W), located in an area of the Atlantic Forest, during the period of June 2000 to July 2001. A total of 4,595 specimens, belonging to 28 families, have been collected. Braconidae, Eulophidae, and Scelionidae, were the most common families, with relative abundance of 22.5%, 14.32%, and 13.12%, respectively. Sixteen families showed the relative frequency lower than 1%. A preliminary list with 47 genera of some of the families is included.

Himenópteros parasitóides (Insecta, Hymenoptera) coletados em cultura de soja (Glycine max (L.)) Merril (Fabaceae), no município de Nuporanga, SP, Brasil

“…Comparando-se estes resultados com aqueles obtidos por PERIOTO (1991), PERIOTO et al (2002), AZEVEDO & SANTOS (2000), AZEVEDO et al (2002) e DALL´OGLIO et al (2000 observa-se que, de forma geral, tem sido amostrado um maior número de superfamílias de himenópteros parasitóides em áreas de vegetação nativa que em agroecossistemas monoculturais. De acordo com dados obtidos por aqueles autores, nas coletas realizadas em áreas de Mata Atlântica, em vegetação de cerrado e em um transecto de cultura de eucalipto/mata nativa, o número de famílias de himenópteros parasitóides representadas variou de 25 a 30, enquanto que em agroecossistemas monoculturais, como nas culturas de algodão e no presente estudo, este número foi de 19 e 15, respectivamente.…”

Drivers of Parasitoid Wasps' Community Composition in Cacao Agroforestry Practice in Bahia State, Brazil

“…A higher parasitoid family richness in both cacao management systems than found in natural Atlantic rain forest areas was evident. In four studies carried out in preserved forest areas, in the Espírito Santo state, an average of 28 families of parasitoid wasps was found (Azevedo, 2000;Azevedo, 2002;Azevedo, 2003;Alencar, 2007). In forest areas impacted by human activities, this number falls down to 19, as found by Perioto et al (2000); Perioto, Lara, Santos & Selegatto (2002); Perioto, Lara, Santos & Silva (2002) in intensive management agroecosystems (soybean, cotton and coffee), suggesting that the current cacao agroforestry systems has a high conservation role for the parasitoid fauna.…”

“…They play a crucial role in natural pest population regulation (LaSalle, 1992). The world literature on the group is vast, and there was a huge effort to understand parasitoid community structure in Atlantic rain forests (Azevedo, 2000;Azevedo, 2002;Azevedo, 2003;Perioto, 2003;Alencar, 2007;Gnocchi, 2010). We have some knowledge on the environmental drivers of parasitoid wasps' diversity in cacao agroforestry: parasitoid wasp's diversity responds to shading tree species richness and density, and these relationships are altered among seasons (Sperber, 2004).…”

Behavioral ecology of Heteragrion consors Hagen (Odonata, Megapodagrionidae): a shade-seek Atlantic forest damselfly

“…The RBDB is a preserved area of Atlantic forest with 2910ha, in a mountain relief with altitude varying from 200 to 800 m, a subhumic climate with the moisture usually higher than 70%, 1500 mm of average annual rainfall and mean temperature of about 22°C (Azevedo & Santos 2000). The area is mainly occupied by a montane short-heighten tropical forest (Rizzini 1979), with the presence of many important floristic resources that includes the peroba (Aspidosperma, Apocynaceae); macanaíba (Bowdichia, Leguminosae); jacarandá (Dalbergia, Leguminosae); jequitibá (Cariniana, Lecythidaceae) and cedro (Cedrela, Meliaceae).…”

There are also clusters of secondary forests with nearly 50 years of regeneration in areas previously occupied by coffee plantations (Azevedo & Santos 2000). Heteragrion consors is a forest dragonfly present at the core of the Atlantic forest in Brazil (from São Paulo to Bahia states) (Lencioni 2005).…”
