RESUMO:

Habitat management in agricultural landscapes to include species diversity of flowering plants are important to increase or maintain functions. multiple, such as pollination and biological control. Given the above, the The main objective of this study was to evaluate the effect of attractive flowers on the insect regulation environmental services (pollination and biological control) in two nightshade species, the tomato (Solanum lycopersicum L.) and the eggplant (Solanum melongena L.). The dissertation study was divided into two articles: the first article was carried out in commercial tomatoes (6200 m²) in the municipality of São José dos Quatro Marcos (Mato Grosso, Brazil). the design experimental was completely randomized with 15 plots of 5 x 4 meters, consisting of 16 tomato plants, with two treatments 1) tomato without strip of attractive flowers (control); 2) tomato striped with attractive flowers of coriander and sorghum. The sampling of pollinating insects and natural enemies was performed with Bee bowls trap and active collection for 8 days at flowering for coriander and 8 days for sorghum. Tomato production was verified by weight of the fruits of 8 plants/plot. Data were analyzed by t-test for compare the richness and abundance of insects between treatments. The production of tomato was analyzed by multiple regression to verify the effect of treatments (x1), insect diversity (x2) and x1:x2 interaction. THE abundance of natural enemies was greater in tomatoes with attractive stripes with flowers of coriander (p = 0.03) and the richness of pollinators was higher in striped tomato of sorghum flowers (p=0.05). The effect of the two bands of flowers intercropping (cilantro + sorghum) increased the total abundance of enemies by three times natural (IN) in tomato with flower bands (p= 0.04). Tomato production does not responded to the use of attractive flower bands and insect diversity. O second article was carried out in eggplant plantation (2320 m2 ) in the municipality of Cáceres (Mato Grosso, Brazil). The sample design was entirely randomized design consisting of 2 treatments, control (eggplant without attractive flowers, plots) and eggplant + sorghum flower strip with 5 repetitions and the total of 10 installments. For sampling of beneficial insects, the same methodology as the first article. Tomato production was verified by fruit weight, size (cm), diameter and number of fruits in 10 plants/plot. Statistical analyzes were the same used in the first article. Both in the evaluation of natural enemies and in pollinators a richness and abundance were greater in the plots that contained flower bands sorghum attractants. Eggplant production in fruit size was favored by the abundance of natural enemies and number of fruits by the method of open pollination. Thus, the planting of attractive flower strips of coriander and sorghum in tomato and sorghum in eggplant has the potential to favor the increase in biological control and pollination services.
