Diversified and monoculture, contrasts in some parasitoids community of coffee crop

Abstract

The diversification of the agriculture is a practice that is getting focus in the last decade, but it always was the natural way. The diversification, being anthropomorphic or natural, brings benefits to the crop, farmer, and the environment. One way possible to restore the diversity of the crop, is planting trees along the culture. Doing this, we can restore the diversification and help to improve ecological function, as pest control. This work was conducted at Fazenda da Lagoa, Santo Antonio do Amparo municipality, Brazil in a coffee plantation diversified with different tree species, being them Avocado, Macadamia, Mangium, Teak and Red Cedar. The insects were collected utilizing yellow plastic pan traps left in the field for a 48h period. Each tree species was sampled separated and a monoculture coffee as control. We found 254 insects in 40 species being 22 species of Braconidae, six species of Eulophidae and 12 Mymaridae species. Our results showed that all tree species had a greater insect richness than Monoculture coffee with Avocado (16), Mangium (18), Cedar (16), Macadamia (19), Teak (16) and Full Sun (10), also we found more abundance of parasitoids at the diversified coffee than in monoculture.
