科罗拉多马铃薯甲虫成虫或其幼虫对马铃薯或番茄植物叶片的损伤诱导蛋白酶抑制剂在暴露于空气的整个植物组织中的快速积累。这种昆虫损害的效果可以通过机械伤害叶子来模拟。受伤后，因子从受损叶片中迅速运输出来，受损叶片和邻近叶片中的蛋白酶抑制剂水平在几小时内显着上升。动物肠道主要蛋白酶抑制剂的快速积累可能是一种防御机制。
Wounding of the leaves of potato or tomato plants by adult Colorado potato beetles, or their larvae, induces a rapid accumulation of a proteinase inhibitor throughout the plants' tissues that are exposed to air. This effect of insect damage can be simulated by mechanically wounding the leaves. The transport of a factor out of damaged leaves takes place rapidly after the wound is inflicted and the levels of proteinase inhibitor, in both damaged and adjacent leaves, rises strikingly within a few hours. The rapid accumulation of a powerful inhibitor of major intestinal proteinases of animals in response to wounding of the leaves is probably a defense mechanism.
