The purpose of this study was therefore to assess local knowledge and experience of beekeepers in Tigray regional state of Ethiopia with regard to colony selection and management practices during purchase and multiplication. Respondent selection was carried out based on the existing conventional agroecological zones namely Dega (highland), Kolla (lowland) and Weinadega (midland). Four woredas (districts) from Dega zone, and three from each of Kolla and Weinadega zones were sampled. A total of 185 beekeepers were interviewed to understand the criteria they were using to select colonies. Preference ranking data were indexed using linear programming. The result indicated that beekeepers were using six local selection criteria namely worker bee population, body color, comb building direction, aggressiveness, honey yield history and age of the colony ordered according to their preference rank from 1 to 6. Beekeepers understood that selection of honeybee colonies was important because productivity, management easiness and agroclimatic adaptation of colonies are different for different colonies. As a result colonies with dominant black colored bees were chosen as first priority for their merits of better honey productivity, tolerance to absconding and multiplication easiness in Weinadega and Kolla agroecologies. However, red/yellowish colored bees were preferred in Dega agroecology.  aApiculture  aBeekeepers  aHoney bee colonies  aLinear programming  aSelection criteria  aSystem optimization  aAbelha  aApicultura  aColônia  aMétodo de otimização  aPequeno produtor  aProgramação linear  aSeleção  aApicultores  aColonias de abejas mielíferas  aCriterio de selección  aEtiópia  aOptimización de los sistemas  aProgramación lineal  aTigray1 aABRAHA, Z.1 aGEBRE, A.1 aDRUMOND, P.
