植物是天然产物的重要的宝库，植物源除除虫剂的研究与开发，除了将原材料或

Treasure plants are important natural products, in addition to research and development of botanical pesticides, in addition to the raw material or a metabolite directly into preparations, the more important is studied chemical structure and mechanism of the active ingredient, the purpose of discovered that new biologically active lead compound together, and then screened, and the creation of new chemical-free pesticides.

Plants are an important treasure trove of natural products, plant sources in addition to insect repellent research and development, in addition to raw materials or their metabolites directly processed into preparations, more important is the study of its active composition chemical structure and mechanism of action, the purpose is to find new bioactive lead compounds, and then screening, creating new and chemical-free pesticides.

Plant is an important treasure house of natural products. In addition to the research and development of insecticidal agents, in addition to the direct processing of raw materials or their metabolites into preparations, it is more important to study the chemical structure and action mechanism of its effective components, with the purpose of discovering new bioactive compounds, and then screening and creating new pesticides without chemical agents.
