RESUMO:

Pest management according to agroecological guidelines, which results in chemical residue free products is a challenge for researchers in Agroecology. One of the best practices available to achieve that, is conservative biological control (CBC). In addition to being an ecologically based and low energy demanding practice, CBC may modify the layout of the agricultural landscape, increase the biodiversity of insects, cre ate shelter for natural enemies, thus providing conditions for them to feed and reproduce locally, resulting in decreasing populations of pests. Attractive plants used in CBC offer food resources and refuge for mating and oviposition to arthropods, thus keeping near-crop breeding grounds. The objective of this thesis project is to develop a prospective study of plants with potential for attractiveness of natural enemies. The experiments will be conducted under field conditions at Embrapa Agrobiologia in Seropédica-RJ. The studies will be carried out in two phases, the first being the prospection of plants with potential for attracting natural enemies and the second the evaluation of the most promising plants for the management of phytophagous arthropods in diversified agroecosystems. In both evaluations surveys and identification of the entomofauna associated to the plant species will be performed. For the prospective study six species of plants will be used, Cosmus sulphureus (Asteracea); Canavalia ensiformis and  Crotalaria spectabilis (Fabaceae), and Foeniculum vulgare (Apiaceae) .This experiment will be conducted on 3x4 meter plots, 5 meters apart from each other, on a randomized block design and four replicates. The plants with the greatest potential for natural enemy attractiveness will be evaluated as intercrops within vegetables. The plants used in this second stage will be chosen mainly because of their attractiveness, prevalence of families of natural enemies important to the crop, period of time during which the natural enemies remain in the plants, absence of pests and diseases common to the main crop and multifunctionality in the property. The entomofauna will be sampled biweekly with the aid of a motorized sucker. A recommendation of an attractive plant mix will be suggested as a tool for the management of insects using local natural enemies in agroecosystems.
