摘 要：
本研究旨在为配制凹纹胡蜂Vespa uelutina auraria Smith的人工饲料提供基本理论依据。2015年7月20日至7月24日,室外招引凹纹胡蜂,以分别添加了2‰、6‰和10‰复合液体维生素的40%蔗糖溶液作为试验组,相同浓度的蔗糖溶液作为对照,观察其对4组不同食物的访问次数和访问时间。结果表明,凹纹胡蜂对2‰复合液体维生素组访问次数最高,极显著高于对照、6‰和10‰维生素组(P<0.01),而对含有10‰复合液体维生素的糖溶液组访问次数最低。此外,凹纹胡蜂访问2‰维生素组和6‰维生素组的时间差异不显著(P>0.05),但均极显著高于对照组和10‰维生素组(P<0.01)。研究结果表明,凹纹胡蜂对添加了2‰维生素的蔗糖溶液具有显著偏好。

摘 要：
This experiment was conducted to investigate the effect of different amount of multiple vitamins on the foraging preference of wasps. We hope that our work could provide a theoretical basis for further making artificial diet of wasps. Here,we investigated foraging frequency and foraging time of wasps Vespa uelutina auraria Smith to asses their visiting preference when foraging on 4 food groups of 40% sucrose solutions that were added with 0‰,2‰,6‰,10‰ of multiple vitamins,respectively,from July 20 to July 24,2015. Four feeders containing these 4 food groups,respectively,were in a line to attract wasp visits. The results demonstrated that the foraging frequency of wasps feeding on the 2‰ multiple vitamins group was very significantly higher than that of wasps feeding on the other groups( sucrose solutions added with 0‰,6‰ and 10‰ multiple vitamins,respectively)( P < 0. 01). Among the four groups,there was lowest foraging frequency for wasps feeding on the group of sucrose solution added with 10‰ multiple vitamins. According to the average foraging time,wasps preferred to the two food groups contained 2‰ and6‰ multiple vitamins,and the foraging time of wasps feeding on the two groups was very significantly longerthan the time of wasps feeding on the control group and 10‰ multiple vitamins group( P < 0. 01),but there was no significant difference between the first two groups( P > 0. 05). It is concluded that the visiting preferences of wasp vary on different concentrations of multiple vitamins in sucrose solutions. And wasps prefer to the sucrose solution added with 2‰ multiple vitamins,according to a comprehensive comparison for foraging frequency,foraging time and feeding amount of wasps foraging activities on different feeders.Our work sheds light on the foraging preference of wasp for different concentrations of multiple vitamins,which were previously seemed be neglected. However,much work remains to be done in order to clarify the chemical composition of wasp artificial diet for the commercialized breeding.
