Sugar syrup has been used in tree different ways to attempt to enhance pollination. 1) Feeding scented syrup to direct bees ( ex K. v. Frisch 1930s - 1950s) 2) Spraying sugar syrup on trees to attract bees (ex Minderhound and Roberts (1948 - 1950ish) 3) Feeding syrup inside hives to convert nectar collectors to pollen gathers (ex J. B Free 1965 - ) I am interested in any information on, if and where any of the above methods are currently used. I am also looking for any early (< 1948) (popular or otherwise) references to spraying crops with sugar syrup. Any help would be greatly appreciated Regards Mark Mark Goodwin Hort Research Ruakura Research centre Private Bag 3123 Hamilton New Zealand EMAIL [log in to unmask] Phone 64 07 838 5049 Fax 64 07 838 5085
