Reprint BEES AND CRANBERRIES Each year Wisconsin cranberry growers spend thousands of dollars for the rental of tame honey bees in an attempt to effect better pollination.

What helps offset these limiting factors is the profuse bloom in a bed of cranberries, along with the extended period bloom is available on a marsh. It is generally agreed that bumble bees are without doubt the most beneficial insect pollinators on a cranberry marsh. The reasons to support this belief is that the bumble bee is a tireless worker, really boroughs upon the blossom searching fpr food and works regardless of the weather conditions. Several species of bumble bees are found in Wisconsin and the queen is the only one that overwinters. lf something happens to her before she raises her brood in the spring, her loss is quite severe. Young brood can also be killed by heavy rains, fires, etc., so a very limiting effect on bumble bee populations defends on the number of young that butvive. Bumble bees live in the ground and are very bond of new, fibrous cranberry dykes and dams. Clean cultivation and spring burning on most marshes quickly eliminate homesites fpr them. Upland areas generally have the highest pojulationsj especially so on cut over areas there there are many old stumps and large numbers of wild flowering plants. It is very doubtful if it would be practical to try and create nesting sites for bumble bees. There are a large number of solitary Wasps: bees, flies that inhabit beds, dykes, dams, and nearby upland areas, that visit cranberry blossoms and probably help some in pollination. Most of these insects are killed or their numbers seriously depleted by pre-bloom dusting with insecticides, From the above, it appears that tame honey bees are the only insects we can possibly be assured of to act as a supplement in cranberry pollination. Some growers have tried to raise their own bees but unless a person has the genuine interest, plus t enough time to devote to them, the results are usually disasterous. If a grower desires to use honey the following based on practical bees as a supplement, we suggest experience and schooling: 1, Demand and use only strong colonies, as weak colonies are worthless. Strong colonies contain 40-50 M bees and can be identified by the number uncoiling cut's of the hive body in large numbers. Another indication is two or three ''supers'' on the hive body, which generally indicates the colony is strong and making considerable honey.
