利用聚丙烯酰胺凝胶电泳及薄层扫描技术，分别测定并分析了感染异源粉纹夜蛾核型多角体病毒后的银纹夜蛾５龄幼虫１２、３６、７２、１０８小时后，虫体血淋巴有关病理生化指标的变化。结果显示，异源病毒感染在早期即对虫体血淋巴蛋白代谢发生影响，尤以糖、脂蛋白的变化显著 By using polyacrylamide gel electrophoresis and TLC scanning, the 5th instar larvae of S. constella were infected with T.alicocephalus nuclear polyhedrosis virus at 12, 36, 72 and 108 hours respectively. Changes of body pathological and biochemical indexes in hemolymph. The results showed that heterologous virus infection in early hemolymph protein metabolism, especially sugar, lipoprotein changes significantly
