摘要

Sweet bell pepper is the most important greenhouse vegetable crop nowadays in The Netherlands. It is grown on an area of 1200 hectares, and about 8000 people are working in these greenhouses. One third of these workers develop sooner or later an occupational allergy against the sweet bell pepper pollen. The symptoms range from itching, blocking of the nose as well as a snivelling nose, to asthma. The pollen is falling down from the flowers when the plants are shaken, which occurs when people are cutting fruits or when they prune or twine the plants. In a pilot study in 2001 it was shown that honeybees could discard the pollen from the flowers and that this resulted in a reduction of allergic complaints. Therefore, a more extensive study was conducted in 2002, with more nurseries and more (allergic) labour people involved, and during a whole season. In this study four questions were addressed: do honeybees reduce the amount of pollen in the greenhouse? If so, how many bees are needed? How do the colonies develop in the greenhouses? Does it help to reduce the allergic complaints. Greenhouses were placed in three groups: without bees, with few bees and with many bees. Greenhouses were frequently visited to check the development of the bees and if necessary to replace colonies, and to check the number of Powers with and without pollen (= pollen removed). The nurseries were visited three times to collect data about the allergic complaints of the people, once before and two times after honeybee introduction. Without bees only 0-30% of the flowers did not possess pollen, with bees this ranged from 50-90%. Bees also reduced the number of pollen grains per flower. Two colonies per hectare proved to be enough to reduce the number of flowers with pollen to20% and lower. The bee colonies could be used for about ten weeks, after that they were too weak. This was independent of the number of hives per hectare used. The introduction of honeybees resulted in a significant reduction of allergic complaints, andthe reduction positively correlated with pollen removal and with the bee densities applied.
