虫害严重威胁粮食安全,为了控制虫害,每年要消耗数百万吨的杀虫剂。但是,几乎所有杀虫剂都会危害生态系统,大部分对人体有害,某些还会被富集在食物链中。植物在与昆虫长期的共进化过程中,进化出了非常多样而有效的自我防御机制。相对于野生植物,农作物抗虫性低是由于在人工驯化和选育过程中往往只重视了产量和株型,而 Pests are a serious threat to food security and millions of tons of pesticides are consumed each year to control pests. However, almost all pesticides endanger ecosystems, most of which are harmful to humans and some are enriched in the food chain. Plants evolved a very diverse and effective self-defense mechanism during their long co-evolution with insects. Compared with the wild plants, the low pest resistance of crops is due to the fact that in the process of artificial domestication and breeding, the yield and plant type are often only emphasized
