Major known defense chemicals include plant secondary metabolites, protein inhibitors of insect digestive enzymes, proteases, lectins, amino acid deaminases and oxidases.

目前已知的防御化合物主要包括植物次生代谢物质、昆虫消化酶(蛋白)抑制剂、蛋白酶、凝集素、氨基酸脱氨酶和氧化酶。

Weakness: the pollution of the environment, killer predators, pests drug-resistant produce, cause secondary pests for the main insect pests rise.

缺点：污染环境，杀伤天敌，害虫抗药性产生，导致次要害虫上升为主要害虫。

The plant secondary metabolite and the insect semiochemical are the important research field in chemical ecology.
