Riqueza e interação entre besouros Cetoniinae e plantas em ambientes introduzidos e antropizados na Mata Atlântica

Abstract

Cetoniinae beetles are commonly known as beetles of flowers or fruits. Cetoniinae is a subfamily of Scarabaeidae (Coleoptera: Scarabaeoidae). This group consists of small to medium-sized beetles (0.3 to 13.0 cm), with typically diurnal. O role of these beetles ecosystem is little known, and its ecology and behavior. Therefore, the present study had as main objective to register the diversity of Cetoniinae beetles in areas exotic vegetation (pasturelands and eucalyptus plantations) and native vegetation (Mata Semidecidual) the richness of species throughout the seasons (dry and wet), check the color of Cetoniinae beetles reflect environmental feature where they were found and compare the abundance sampled at different heights (1.5 m and 6 m) with attractive baits (Pineapple with broth cane and banana with sugar cane broth). In addition, record information about the floral visitation habits, and the interactions between Cetoniinae beetles and plants, and quantify the species visited throughout the seasons climáticas.Dessa way, data samples were taken monthly from July 2014 to June 2015, on the New River County, MG, using traps carpotrampa type, with attractive baits in Eucalyptus area, Pasture and Semidecidual Forest fragments. Seven species distributed in four genera were collected. In Semidecidual Forest fragments (N = 159) diversity (H '= 1.395) was higher than in other areas and abundance greater than the areas of eucalyptus plantation (N = 95) (H' = 1.093), but less than in the pastures (N = 222) (H '= 1.082). Cetoniinae looting two species of two species of plants were found. The Cetoniinae beetles, occurred from August to February, the greatest wealth observed (seven species) took place in December. The coloring of individuals demonstrates relation to the habitat where they were found. The species found in the three environments present a cryptic coloration that may have led to camouflage in both habitats. This study contributed to the knowledge of the diversity of beetles Cetoniinae in anthropogenic areas and native vegetation. Besides contributing to the understanding of the relationship of the color of the beetles with the habitats where they were found and the plants interaction behavior, and to improve the methods used for sampling Cetoniinae beetles.
