Abstract

Bees are spread throughout the Brazilian territory, being responsible for the proliferation and conservation of many plant species, reinforcing the importance in the production of these foods. The main goal of the experiment was to evaluate the efficiency of the pollination process, in open and controlled environments, on cucumber crop (Cucumis sativus L.) cultivar Marketmore 76. The design was completely randomized, with three treatments, two in closed greenhouses and one in an open greenhouse with free access to all pollinators and twenty repetitions per treatment, each plant was a repetition. In treatment 1 (T1), in a closed greenhouse without pollination, control treatment, in treatment 2 (T2), in a closed greenhouse, a colony of Melipona scutellaris, controlled pollination, was introduced during flowering, and in treatment 3 (T3), open greenhouse, with free pollination. The parameters evaluated were the frequency of bee visitation in flowers, average weight (PM) and average fruit diameter (CIRC), average weight (PMS), amount (NT) and dry matter content (MS%) of seeds. The frequency of bee visits to flowers was obtained by visual observation of male and female flowers, between 7:00 a.m and 17:00 p.m., for five consecutive days for 20 minutes every hour. According to the data obtained, the treatment 3 (T3), as it had no restrictions, was the one that registered the highest number of visitations, with peak hours in the intervals between 9:00 a.m. and 13:00 p.m., and it was verified the presence, in abundance, of Apis mellífera linguística. The pollinated fruits, equivalent to T2 and T3, presented significant differences for the parameters PM456g, CIRC21,3cm, PMS12,35mg, NT277, MS21%, higher 27,7%, 10,27%, 34,9%, 39,35. % and 23.81% respectively in relation to non-pollinated fruits of T1. T3 obtained total production (kg) of 24 and T1 and T2 10 and 5, respectively. With this experiment it was possible to prove the importance of bees as pollinating agents.
