The damage of strawberry blossom weevil (Anthonomus rubi) was estimated in the raspberry cultivars in collection of the Polli Horticultural Research Centre during the flowering periods of 2003-2007. The total number of flower buds was counted and inspected for damages in the plants of 14 cultivars (‘Aita’, ‘Algonquin’, ‘Alvi’, ‘Arta’, ‘Glen Ample’, ‘Haida’, ‘Helkal’, ‘Ivars’, ‘Nagrada’, ‘Norna’, ‘Novokitaivska’, ‘Ottawa’, ‘Tomo’, ‘Veten’). In 2004, 2005 and 2007 there were no blossom weevil damages. In 2003 and 2006 damages were found. In both years the flowers of ‘Glen Ample’ were the least damaged ones (on an average 1.0%). Also ‘Ivars’ and ‘Algonquin’ flower buds had very little damage (2.0 and 2.5%, respectively). At the same time, ‘Helkal’ (23.8% of buds damaged) and ‘Ottawa’ (15.6%) were the most affected cultivars. The studies on different raspberry growing methods at the Polli Horticultural Research Centre in 2003 and at the Rõhu Experimental Garden in 2004 showed that strawberry blossom weevil’s damages are also depending on mulching materials.
