| dc.description.abstract | This study was initiated with the objective of getting responses of honeybee (Apis mellifera monticola) to simple queen rearing techniques (SQRT) and performance evaluation of reared queens under farmer’s condition in Lay-Arimachiho district of central Gondar zone of Amhara region from September 2021 to December 2022. Because the district was found in the Northern mountainous area of the country and also Apis mellifera monticola was found in the Northern mountainous area of the country. At present, honeybee colony is at a state of continuous declin e and absconding is becoming the main constraints of beekeeping development and more diffic ult to get new colonyevery year. 4 representative kebeles (Shumara Lomiye, Tikle Dengay city, Kerker Balegziabher, and Chira) were selected purposively based on colony population distrib ution their suitability for beekeeping production and accessibility to transportation and from th em ten technology adopter beekeepers were selected purposively. A total of 15 modern honeybee colonies with first supper and uniform strength were selected and assigned equally and randomly to the three SQRT and from each mother colony four daughter colonies were selected for further performance evaluation. Honeybee colonies were evaluated for different parameters (number of queen cell constructed, larvae developed into pupae, emerged queen, brood area coverage, empty cells per 100 cells, colony absconding, and honey yield) were evaluated, and data were collected from these parameters. All collected data was analyzed using SPSS version 26, SAS 9.4, Microsoft Excel software, and descriptive statistics where mainly used. The success rate of tested queen rearing techniques shows a remarkable variation. The overall mean of queen cell construction, developed pupae, and emerged queen were 13.13±2.26, 10.27±1.87, 1.00±0.00 respectively. The overall mean brood area, number of empty cells per 100 cells, and honey yield from daughter colonies was 6528.65±2236.69, 8.2±3.61, and 16.71±5.65kg, respectively. The result of the study on queen pupae shows that in all SQRT has high emergence percentage. Miller technique in the active season (September to November) exhibited significantly (p<0.05) higher brood rearing compared with the rest two SQRT. The solidity of brood of honeybee colonies reared by SQRT has significant difference in empty cell count in brood nests and affected by the rearing techniques. Similarly, the number of queen cells constructed during brood rearing season shows significant variation among colonies reared through SQRT. From the total reared daughter colonies91.67% and 86.67% of mother colonies were adapted. Due to the difference in the number of worker bees there was si gnificant honey yield variation in the three SQRT at p<0.05. From the three SQRT comparativ ely better in honey yield for the colonies obtained from splitting technique. In general from the se techniques, Miller technique shows better result in all parameters except honey yield evaluation. Based on the result from the study, even if Miller was the best QRT, it is recommended that splitting was a useful technique as it doesn’t demand any additional equipment and facilities like that of the other queen rearing techniques in the study area. Finally, Pre-scaling up of the technology would be better applied in small, interested groups. It could be applied on targeting increased number of honeybee colonies as well as to increase honey yield under farmer’s condition. Using splitting queen rearing technique could be implemented as a better technique for resource poor and less skilled local beekeepers. More research should be conducted on the consequences of different factors on the queen rearing techniques of honeybees within the study area. Strengthening of colonies before queen rearing should not be forgotten. | en_US |
