THE cranberry industry of the United States is now about 150 years old. Growing cranberries, one of the very few native American fruits now in commerce, is an important economic enterprise in the states of Massachu- setts, Wisconsin, New Jersey, Washing- ton and Oregon. A total of about 21,000 acres are devoted to this crop which had a value in 1966 of about 26 million dollars in the unprocessed form. Despite rapid improvements recently made in culture methods and in yields per acre, the subject of pollination of cranberries has received very little study. Dr. Chester Cross, director of the Mas- sachusetts Cranberry Experiment Sta- tion, referring to the prevalent opinions regarding the occasional failure of cran- berry flowers to set good crops, presents a wide divergence of reasons, including a belief in wind pollination (1). The importance of the role of the honey bee in cranberry pollination has only been proven relatively recently, by Farrar and Bain in 1947 (2). Before this there had been two contrasting views regarding the mode of cranberry pollination. Franklin recognized the value of bees as necessary agents in accomplishing pollination but, at that time (1940), he considered that the population of wild bees in Massachu- setts bog areas was sufficient to pro- mote adequate set (3). Roberts and Struckmeyer (4), working in Wiscon- sin in 1941, gave the opinion that pol- lination was apparently brought about by wind borne pollen reaching the pis- til. They stated that honey bees did not touch the pistil in visiting the cran- berry flowers but that "their jarring of the blossoms during their visits would appear to be of prime importance in any aid to pollination which they ren- ; Farrar and Bain (2) showed very clearly that honey bees do work blos- soms in such a m
