Investigations were carried out to evaluate Africanized and Carniolan hybrid Apis mellifera honeybees in royal jelly production. Ten colonies were randomly collected in nature and housed in Langstroth beehives. Each hive was having two nuclei with five frames. In superior nucleus frame was containing 28 acrylic cups in two bars. The five colonies with the best production remained in the experiment and their queens replaced by the respective daughters. Carniolan queens were placed in the five Africanized honeybees colonies with lower production. The hybrid Carniolan showed a higher production (P=0.0001) of royal jelly per colony, in three-day collect (3.95 ± 2.92 g) when compared to the Africanized honeybees (2.23 ± 2.13 g). The Carniolan also had a higher percentage of larvae acceptance (55.45 ± 36.7%) compared to the Africanized honeybees (35.8 ± 28.3%).
