蛋白酶抑制剂在害虫防治中的研究与应用

Study and application of proteinase inhibitors on pest control

蛋白酶抑制剂是一种抑制蛋白酶分解活性的蛋白质,对许多昆虫的生长发育有明显的抑制作用。蛋白酶抑制剂扰乱昆虫正常代谢,最终导致昆虫发育不正常甚至死亡,在害虫防治中有良好的应用前景。本文分别对蛋白酶抑制剂种类、分布及抗虫性进行了介绍,同时探讨了蛋白酶抑制剂的基因转化及应用前景。

Proteinase inhibitors, a series of proteins, can inhibit the activity of proteinase. The classification,structure, distribution and insect inhibition of proteinase inhibitors were studied in this paper. In addition, the genetic transformation and application of proteinase inhibitors were prospected. Proteinase inhibitors can significantly inhibit the growth and development of insects, interfere with normal metabolism of insects and finally lead to abnormall develop meat or die.
