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.
马铃薯或番茄植株的叶片被成年科罗拉多马铃薯叶甲或其幼虫咬伤后，会在暴露于空气中的整个植株组织中迅速积累蛋白酶抑制剂。昆虫损伤的这种效应可以通过机械损伤叶片来模拟。损伤后，因子迅速从受损叶片中运输出来，并且在几小时内，受损和相邻叶片中的蛋白酶抑制剂水平显著升高。叶片受伤后，动物主要肠道蛋白酶的强有力抑制剂迅速积累，这可能是一种防御机制。
