In the Semiarid region of Northeast Brazil, adverse environmental conditions such as high radiation and temperature affect the balance of homeostasis of the colonies of Africanized honey bees ( Apis mellifera L.). This research aimed to evaluate the rate of acceptance of Africanized honey bees larvae (Important stage of process of queen-rearing) in hives installed in the shade and under full sunlight in the semiarid climate of Northeastern Brazil. 10 colonies of honeybees (5 in the shade and 5 under full sunlight) were orphaned and prepared with young workers and food, having standardized biomass (equal population conditions) to receive frames containing 60-100 queen cell cups with larvae up to 24 hour-old. The acceptance percentage of transferred or grafted larvae to each colony was measured 72 hours after carrying out transfers and means were compared by the Student’s t-test at 5% probability. The colonies under shade conditions showed acceptance rate of 68.82 ± 17.03%, significantly higher (P = 0.0044) than the colonies subjected to direct sunlight with only 52.13 ± 16.29%. Thus, for the production of queens and royal jelly of Africanized honeybees in the semiarid climate of Northeast Brazil, it is strongly recommended the installation of apiaries in shady locations. Taxa de aceitacao de larvas de abelhas africanizadas em colmeias mantidas em sombreamento e sob exposicao solar direta no Nordeste Brasileiro No Semiarido do Nordeste Brasileiro, as condicoes adversas do ambiente como alta radiacao e temperatura afetam o equilibrio da homeostase das colonias de abelhas africanizadas ( Apis mellifera L.). Este trabalho objetivou avaliar a porcentagem de aceitacao de larvas de abelhas africanizadas (etapa importante do processo de producao de rainha) em colmeias instaladas a sombra e sob radiacao direta do sol na regiao semiarida do Nordeste Brasileiro. Para isso, 10 colonias (5 no sol e 5 na sombra) foram orfanadas e tiveram a biomassa padronizada para receber quadros portando de 60 a 100 cupulas contendo larvas com ate 24 horas de vida. O percentual de aceitacao das larvas transferidas para cada colonia foi avaliado 72 horas apos a realizacao das transferencias e os dados foram comparadas pelo teste t - Student a 5% de probabilidade. As colonias sob condicoes de sombra apresentaram taxa de aceitacao de 68,82 ± 17,03%, sendo significativamente maior (P = 0,0044) do que as colonias submetidas a radiacao direta do sol, com apenas 52,13 ± 16,29%. Conclui-se que para a producao de rainhas e de geleia real de abelhas africanizadas no semiarido nordestino, torna-se extremamente recomendavel a instalacao de apiarios em locais sombreados.
