糖类对美国白蛾生长发育及消化酶活性的影响
Effect of carbohydrates feeding on development and digestive enzyme activity of Hyphantria cunea
摘要
Abstract
[Objective]The impact of carbohydrates on the growth,development and digestive enzyme activity of Hyphantria cunea(American white moth)was investigated,aiming to provide a scientific foundation for establishing an indoor breeding system.[Method]Strictly quantified artificial feed,supplemented with glucose,trehalose and sucrose at 2％and 4％mass fractions,which was summed up to 6 treatment groups,was fed to the 4th instar larvae of American white moth.During the experiment,the body mass,molting rate,mortality and protein content of larvae,as well as the activities of 3 digestive enzymes(α-amylase,lipase and trypsin)were measured.[Result]Supplementation of 2％glucose exerted certain promoting effect on the growth and development of American white moth larvae.The protein content of larvae supplemented with 2％sucrose started with an uprise and then stabilized along the experiment,while others followed decreasing trends.α-amylase activity in the larvae of all the 6 treatment groups showed increasing trends with the experiment,while the activities of lipase and trypsin were declined in the groups treated with glucose and trehalose at both rates.In the treatment added 4％sucrose,glucose and trehalose activities experinced very subtle declines;while in the treatment added 2％sucrose,trypsin activity followed an uptrend,and lipase activity was firstly decreased and then increased.[Conclusion]Sucrose is the most suitable carbohydrate component for the artificial feed of American white moth in comparison to glucose and trehalose.关键词
