高温胁迫对南亚果实蝇成虫多糖和甘油三酯的影响

Effects of Heat shock (42°C) of various durations (5, 15, 30 or 60 minutes daily) for 10 days or 15 days on polysaccharide and triacylglycerol contents of Bactrocera tau adults fed on cucumber were determined systematically by biochemical methods. Loss rates of polysaccharide content increased to 2.04%, 2.08%, 5.04% and 5.93% was observed respectively in 5minutes, 15minutes, 30minutes, 60minutes daily for 15days and except for the flies in 5minutes daily, the accumulation of triacylglycerol of Bactrocera tau increased responding to the treated durations. The above results suggested that under the heat shocks conditions, the utilization of polysaccharides increased, while that of triacylglycerol decreased.
