用核型多角体病毒（NPV）对不同树种叶盘上的舞毒蛾幼虫进行生物测定，发现某些树种对病毒有很强的抑制作用。抑制树叶的酚提取物引起病毒多面体包涵体（PIB）形成大的聚集体。然而，聚集的PIB处理叶提取物和管理的幼虫实验室饮食（无酚）保留毒性。我们的研究结果表明，叶酚类物质，特别是可水解单宁，抑制NPV感染，但可能不会通过聚集在前肠形成的行动。
Bioassays with nuclear polyhedrosis virus (NPV) administered to gypsy moth larvae on leaf disks from various tree species reveal strong viral inhibition by some tree species. Phenolic extracts from inhibitory tree leaves cause virus polyhedral inclusion bodies (PIBs) to form large aggregations. However, aggregated PIBs treated with leaf extracts and administered to larvae on laboratory diet (without phenolics) retain virulence. Our results suggest that leaf phenolics, especially hydrolyzable tannins, inhibit NPV infection, but may not act via aggregations formed in the foregut.
