- W2348448921 abstract "The objective of this experiment was to explore the effects of vitamin C on the development of larvae and the viability of worker bees for Apis cerana cerana. The experiment contained 2 parts: larvae and worker bees' feeding trails. Larvae bees' feeding trail: eight hundred larvae for Apis cerana cerana were randomly distributed into 5 groups with 8 replicates in each group and 20 larvae in each replicate. The larvae in control group( group Ⅰ) were fed a basal diet containing 1.6 mg / kg vitamin C,and those in 4 experimental groups were fed experiment diets supplemented with 10( group Ⅱ),20( group Ⅲ),30( group Ⅳ) and 40 mg / kg( group Ⅴ) vitamin C,respectively. Worker bees' feeding trail: one-day-old worker bees for Apis cerana cerana were distributed into 4 groups with 6 replicates in each group and 24 g( about 300 bees) in each replicate. The worker bees in control group( group Ⅵ) were fed a 1 ∶ 1 sweet water,and those in 3 experimental groups were fed 1 ∶ 1 sweet water supplemented with 50( group Ⅶ),500( group Ⅷ) and 2 500 mg / kg( group Ⅸ) vitamin C,respectively. The results showed as follows: during the development stage of larvae, the body weight of 6-day-old larvae,3-day-old pupae and new-emerged bees was increased firstly and then declined with the increase of vitamin C content,and that in groups Ⅱ and Ⅲ was significantly higher than that in control group( P0.05). The pupation rate and eclosion rate of larvae showed trends similar with body weight. Moreover,the relative expression level of Cu / Zn superoxide dismutase( Cu / Zn-SOD) gene was also increased firstly and then declined with the increase of vitamin C content,and the relative expression level of Cu / Zn-SOD gene of 6-day-old larvae and 3-day-old pupae in experimental groups was significantly higher than that in control group( P0.05). In the aspect of viability of worker bees,the average lifespan of worker bees was increased firstly and then decreased with the increase of vitamin C content. The average lifespan of worker bees in experimental groups was significantly higher than that in control group( P 0. 05),and there was significant difference among experimental groups( P0.05). With the increase of vitamin C content,the survival rate of worker bees was increased firstly and then decreased,while the relative expression level of Cu / Zn-SOD gene of 3,9 and 15-day-old worker bees was decreased. In conclusion,the suitable contents of vitamin C in the artificial diet of larvae for Apis cerana cerana are 11.6 to 21.6 mg / kg; dietary vitamin C content has a great effect on the viability of worker bees for Apis cerana cerana." @default.
