Resumo: | Coffee is very important for Brazilian agribusiness, Brazil is the largest producer and exporter of coffee with over 2.2 million hectares cultivated and an income of more than 600 million dollars. However, the production dynamics is greatly influenced by biotic and abiotic factors. The crop is attacked by various diseases and pests, but there are many natural enemies that perform biological control of both, with emphasis on Prorops nasuta (Hymenoptera: Bethylidae), a parasitoid of the coffee berry borer larvae and Protonectarina sylveirae (Hymenoptera: Vespidae), a wasp that feeds on larvae of leaf miner. Diversification of crops is an important tool to maintain these organisms in agriculture. One way of diversification is the utilization of trees for shading, which help in maintaining and increasing the diversity in the crop and brings improvements to the agroecosystem. Thus this study's goal is to evaluate the influence of some tree species for shading in diversity of parasitoid and wasps in conventional coffee. This study was conducted at Fazenda da Lagoa, in Santo Antonio do Amparo municipality, MG, in conventional coffee plantations shaded with different tree species, which are: Teak, Acacia, Cedar and Avocado planted in two different densities. For comparison purposes, a crop in full sun system was used as a control. The parasitoids collected were identified in families and separated into morphospecies; the wasps collected were identified to species, when not possible to identify, were separated in morphospecies within the genre. We collected 3172 parasitoid individuals belonging to nine superfamilies, 21 families and 263 morphospecies, and 632 individuals of 23 species of wasps. Regarding parasitoids, the Acacia treatment showed greater diversity (3.77) and for wasps, Avocado treatment (1.70) with the highest diversity. The lowest diversity was found in Cedar (0.74) for the wasps and Teak (3.19) for parasitoids. The higher diversity was found in plants with high availability of resources such as nectar, pollen and shelter. Diversification with tree species can bring significant gains to agroecosystem assisting in increasing diversity and maintenance of natural enemies, helping the conservation biological control. |

Entretanto, a dinâmica da produção é muito influenciada por fatores bióticos e abióticos. O cafeeiro é atacado por diversas pragas, no entanto, existem diversos inimigos naturais que realizam o controle biológico dessas pragas, tendo destaque para Prorops nasuta, um parasitoide (Hymenoptera: Bethylidae) que parasita larvas da broca do café e Protonectarina sylveirae, uma vespa (Hymenoptera: Vespidae) que preda larvas do bicho mineiro. A diversificação das lavouras é uma importante ferramenta para manutenção desses organismos na lavoura. Uma forma de diversificação é a utilização de árvores para sombreamento, que ajudam na manutenção e incremento da diversidade nas lavouras e traz melhorias para o agroecossistema. Dessa forma, este trabalho objetivou avaliar a influência que algumas espécies arbóreas para sombreamento exercem na diversidade de parasitoides e vespas em café convencional. O presente trabalho foi realizado na Fazenda da Lagoa município de Santo Antônio do Amparo-MG, em lavouras de café convencional sombreados com diferentes espécies arbóreas, sendo elas: Teca, Acácia, Cedro e Abacate plantados em duas densidades diferentes. Para efeitos comparativos, foi utilizada uma lavoura a pleno sol como testemunha. Os parasitoides coletados foram identificados em famílias e separados em morfoespécies; as vespas coletadas foram identificadas até espécies; quando não possível a identificação, foram separadas em morfoespécies dentro do gênero. Foram coletados 3172 indivíduos distribuídos em nove superfamílias, 21 famílias e 263 morfoespécies de parasitoides; e 632 indivíduos em 23 espécies de vespas. Em relação aos parasitoides, o tratamento Acácia apresentou maior diversidade (H’ = 3,77) e, em relação às vespas, o tratamento Abacate (H’ = 1,70). As menores diversidades foram obtidas no tratamento Cedro (H’ = 0,74) para as vespas e Teca (H’ = 3,19) para parasitoides. As maiores diversidades foram encontradas em plantas com disponibilidade de recursos como néctar, pólen e abrigo. A diversificação com espécies arbóreas pode trazer ganhos significativos ao agroecossistema, auxiliando no incremento da diversidade e manutenção dos inimigos naturais, tal como no controle biológico conservativo.Universidade Federal de LavrasPrograma de Pós-Graduação em EntomologiaUFLAbrasilDepartamento de EntomologiaSilveira, Luís Cláudio PaternoFernandes, Daniell Rodrigo RodriguesHaro, Marcelo Mendes deTomazella, Vitor Barrile2016-04-06T12:48:53Z2016-04-06T12:48:53Z2016-04-062016-02-23info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfTOMAZELLA, V.
