摘要
采用比色法测定嗜卷书虱(Liposcelis bostrychophila)和嗜虫书虱(L．entomophila)体内甘油三酯、 多糖和可溶性蛋白的贮存量。结果表明,嗜虫书虱体内3种物质的贮存量均显著高于嗜卷书虱。在毒死蜱和丁 硫克百威的胁迫下,嗜虫书虱体内3种物质的变化幅度均大于嗜卷书虱,其中甘油三酯的含量先增高后降低, 整体呈现下口抛物线趋势;多糖和可溶性蛋白的消耗率增加。这些说明在毒死蜱和丁硫克百威的作用下,书虱 更多地启动了多糖和可溶性蛋白的代谢,降低了对甘油三酯的利用,以应对杀虫剂的胁迫。
The accumulations of three main energy sources： triacylglycerol, polysaccharide and soluble protein were determined in two psocids, Liposcelis bostrychophila Badonnel and L. entomophila （Enderlein）. The results indicated that the reserves of three energy sources in L. entornophila were significantly higher than that in L. bostrychophila. Exposure of the two psocids to chlorpyrifos and carbosulfan was associated with a significant change of the reserves, and the change range for L. entomophila was greater than for L. bostrychophila. The triacylglycerol responded to the two insecticides with a parabolic increase in the reserves, while polysaccharide and soluble protein responded with an enhancement of the utilization rates. These changes suggested that under the effect of chlorpyrifos and carbosulfan, polysaccharide and soluble protein are the main energy sources, while the utilization of triacylglycerol decreased.
