“…Cucumbers plants of the Aodai cultivar are monoecious and highly dependent on animal pollinators, especially honey bees (McGregor, 1976;Klein et al, 2007). Other investigations have shown that honey bees are also efficient pollinators of cucumbers grown in greenhouses (Nogueira- Couto & Calmona, 1993;Nicodemo et al, 2013). Although the effectiveness of honey bees as pollinating agents of cucumber was already known, our work brings contributions regarding the management of hives into greenhouses, in order to facilitate the maintenance of colonies and pest management of crops when hives are introduced to the greenhouses for pollination services.…”

Although honey bees are efficient pollinators of many crops cultivated in greenhouses, it is difficult to maintain colony strength and consequently pollination efficiency. Many bees die under greenhouse conditions and the colonies rapidly weaken. We examined the effect of adaptations to the hive entrance that allowed control of whether and when bees had access to the outside environment to see how it would affect pollination efficiency and colony condition in greenhouses with flowering cucumber (Cucumis sativus) plants in comparison with colonies that remained constantly inside the greenhouse, previously left in a dark environment or not. We recorded the type and period of visitation to the cucumber flowers, numbers of honey bees entering and leaving the two entrance hives and the effect of this type of management on the quantity of brood and food. Fiveframe Langstroth “nucleus” colonies were equipped with two 30 square centimeter entrances and two 3.0 cm diameter circular openings. Allowing the bees to make visits outside the greenhouse in early morning with redirection of bees into the greenhouse at 8.30 a.m. did not reduce visitation to cucumber flowers in the greenhouse. Maintaining colonies in the greenhouse reduced brood area and food stores. These losses were significantly reduced in colonies that had access outside the greenhouse during the early morning. Another advantage of alternating access to the inside and the outside of the greenhouse was that there was less possibility of interactions between bees and people working on the crop, and also pesticides application could be made without directly affecting foraging bees.
