This experiment was conducted to study the effects of vitamin A on bee population, sealed brood quantity and larva antioxidant of Apis mellifera ligustica. Ten cages of honey bees obtained from a local apiary were used in the study. Honey bees were randomly allocated to 2 groups (control group and experimental group) with 5 replicates each. Bees in the control group were fed the basal diet, and those in the experimental group were fed the diet supplemented with 7 500 IU/kg vitamin A in the basal diet. The results showed as follows: the feed intake, sealed brood quantity, crude protein and T-SOD activities of larva in experimental group were significantly higher than those in control group (P<0.05). The content of MDA of larva in experimental group was significantly lower than that in control group (P<0.05). There were no significant differences among the bee population, protein content and T-SOD activities of larva (P>0.05). Vitamin A supplemented in diet can improve the sealed brood quantity and antioxidant of honeybee larva. The index, such as antioxidant, can be applied in the study of honeybee nutritional requirements.［Chinese Journal of Animal Nutrition, 2011, 23（6）：971 -975］
