本文介绍了植物与昆虫之间的关系、植物杀虫剂最近研究的进展、植物抗虫性的化学及其在抗虫育种中的作用、植物对昆虫的主动防御及其在害虫防治中应用的展望。主要从生物化学及生态学方面进行讨论,指出这四个问题具有内在的联系。对植物杀虫剂的探入研究,今后可能获得对环境安全而对害虫不产生抗药性的新一代农药。研究作物抗虫的遗传基因,可以培育出高抗优良品种。对于植物对害虫主动防御的探索,可以在害虫预测预报上获得新的进展。作者认为在我国开展植物自身控制害虫作用的研究具有深远的意义,将可使害虫综合防治获得划时代的突破。
This article describes the relationship between plants and insects, recent advances in plant insecticides, the chemical nature of plant pest resistance and its role in insect breeding, the active plant defense of insects and their application in pest control Outlook. Mainly from the biochemistry and ecology are discussed, pointed out that these four issues are intrinsically linked. In the future, it is possible to obtain a new generation of pesticides that are safe to the environment and not resistant to pests in the future. Research crop insect resistance genes, can breed high anti-good varieties. The exploration of plant active defense against pests can make new progress in pest prediction. The author believes that the study on the role of plants in controlling pests in our country has far-reaching significance and will enable epoch-making breakthroughs in integrated pest management.
