Abstract:

Plant protease inhibitors as a resisting pest resource was more studied besides Bt gene, the distribution is widely, especially in the leguminosae, solanaceae, gramineae, cucurbitaceae and cruciferae plants. Plant protease inhibitors resisting gene was mainly acquired by two methods and had been transferred in some plants, and obtained the resisting pest genetic engineering plants. Plant protease inhibitors was preliminary applied in the forest trees resisting pest genetic engineering. In this paper, based on the control status of forest trees pest in China, application prospects of plant protease inhibitors in control pest were systematically discussed, meanwhile, the existing problem and solving methods of plant protease inhibitors were also put forward in control of forest tree pest.

Key words: plant protease inhibitor, forest pest control, resisting pest genetic engineering
