Measures to support wild bees and their pollination service.

Original language description

Wild bees contribute to pollination of crops and wild flowers. Their species diversity and abundance have declined during last decades, mainly due to loss of nesting and feeding habitats in response to land use change. This may jeopardize the fruit production in orchards, which relies on bee pollination. We surveyed the diversity of bees in fruit orchards by coloured traps and found more than 20 pollinating bee species in period of fruit blossoming (April – May). When considering the results of summer surveys, we identified in total 140 bee species in orchard sites after 5 years of trapping. Since a majority of these bees nest in the soil, we tested artificial nesting sites in order to to support above-ground nesting bees in fruit orchards. By this way we succeeded to enhance populations of mason bees Osmia bicornis and Osmia cornuta, which contribute to pollination of fruits in the spring. We also tested artificial flower strips as a source of food for pollinators after the fruit-tree blossoming period is over. This is important mainly for the development of bumblebee colonies, which takes several months from spring to summer. Numbers of bumblebee queens, produced in summer, determine the intensity of pollination service supplied to crops in the following year. These measures, applied by crop producers, have a potential to enhance pollination service in agricultural crops.
