自然界中植物抗虫现象是普遍存在的。我国早在后魏年间《齐民要术》中.记述了14种谷子有“早熟、耐旱、(?)虫”的特性。美国1792年首次报道了小麦品种“Vnderhill”对黑森麦瘿蚊的抗性;1831年又报道了苹果品种“wonter,maiatin 能抗苹果绵蚜。1860年前后法国引进有抗性的美洲葡萄作砧木与本国的欧洲葡萄嫁接,控制了葡萄根瘤蚜的严重危害. Plant insect resistance in nature is pervasive. As early as in the late Wei Dynasty in China, “Qi Min Yao Shu” recorded the characteristics of 14 kinds of millet “precocious, drought-resistant and (?) Insects.” The United States reported for the first time in 1792 the resistance of the wheat cultivar “Vnderhill” to Hystrix mosquitoes. In 1831, it was reported that the apple variety “wonter, maiatin was able to resist the apple aphid.” Before and after 1860 France introduced the resistant American grape Grafts are grafted onto their own European grapes and control the serious damage to grape phylloxera.
