 Nuclei for pollination of agricultural crops in greenhouses or in open fields. The nuclei are complete with queen, as only the presence of the queen guarantees correct pollination of the crops by the workers, who would otherwise be disoriented and without stimuli preparatory to pollination.
 The maximum residence time is 20 calendar days for greenhouse crops and 45 days for open field crops. The nuclei are recovered after having performed their pollination service.
