PRELIMINARY RESULTS ON THE REMOVAL RESPONSE OF RUSSIAN HONEY AGAINST BROOD INFESTED WITH SMALL HIVE BEETLES - Removal response of Russian (n = 9) and Italian (n = 9) honey bees against brood infested with small hive beetles (SHB) was compared. SHB-infested brood were obtained as described by Ellis et al. (2003, Naturwissenschaften 90: 532-535) with modifications. For each colony, three sections of brood (58 cm2 each) were caged as follows: control (no beetle), treated (20 beetles) and pulled (20 beetles). Adult beetles were caged for 15 h. Each brood section was examined under the microscope for the presence of perforations and then mapped using photo prints. All brood cells in the pulled section were opened and examined for the presence of eggs, which provided infestation data for the treated section. Brood removal was assessed 20 h after brood frames were returned to their colonies. For analyses, brood cells in each section were grouped as follows: a) NPNS = no perforation on capping and cell wall; b) NPWS = with cell wall perforation only; c) WPNS = with capping perforation only; and d) WPWS = with capping and cell wall perforations.
