Abstract :This study presents the possibility of killing almost all microorganisms such as fungi, bacteria, spore forms, and viruses by sterilization process. European foulbrood insert ignore into journalissuearticles values(EFB); and American foulbrood insert ignore into journalissuearticles values(AFB); is a highly infectious bacterial honeybee disease caused by Melissococcus plutonius and Paenibacillus larvae , respectively. Removal of spores from contaminated beehives is a critical factor in controlling EFB and AFB. The purpose of this study was to evaluate the effectiveness of ultraviolet insert ignore into journalissuearticles values(UV); in killing Paenibacillus larvae spores on PVC, and wood hives. Hives infected with Paenibacillus larvae spores were treated with two UV powers insert ignore into journalissuearticles values(6 and 8 W); for up to 15 min. Sterilization at 8 W for 15 min resulted in a more than 6.6 log reduction in the number of Paenibacillus larvae spores on the PVC hives. Under the same experimental conditions, the reduction in wood hives was 6.2 log. Reductions achieved in Paenibacillus larvae spores on PVC hives after 5, 10 and 15 min of sterilization were significantly insert ignore into journalissuearticles values(p˂0.05); higher than those on wood hives. So it is recommended to sterilize hives contaminated with spores with UV lamps
