甘蔗抗虫机制的研究进展

甘蔗是重要的糖料作物也是潜在的能源作物,而甘蔗的生长过程中长期受到各种虫害威胁。目前用于防治甘蔗害虫主要是通过化学防治和生物防治,带来的害虫耐药性和环境安全问题不容忽视。选育和利用抗虫品种,挖掘甘蔗自身抗虫特性是目前公认的最根本、经济有效和对环境影响最少的办法。笔者首先介绍了不同甘蔗品种对甘蔗螟虫的抗性等级,再从甘蔗的物理抗性和生理生化抗性2个方面阐述甘蔗的抗虫原理,并重点介绍了甘蔗的诱导型生理生化防御体系。全文还就目前甘蔗抗虫研究现状提出建议和展望,以期为培育甘蔗抗性品种以及蔗田害虫综合治理提供参考。

Research Progress on Insect Resistance Mechanism of Sugarcane

Sugarcane is an important sugar crop and a potential energy crop in China. However, the growing process of sugarcane is threatened by various pests. Currently, chemical control and biological control are mainly used to control sugarcane pests, but the problems of pest resistance and environmental safety cannot be ignored. At present, it is generally accepted that the most fundamental, economical and effective methods are to select and use insect resistant varieties and exploit the insect resistant characteristics of sugarcane. Therefore, this paper firstly introduces the resistance grade of different sugarcane varieties to sugarcane borers, and then expounds the sugarcane resistance principle from two aspects of sugarcane physical resistance and physiological and biochemical resistance, and emphatically introduces the sugarcane induction physiological and biochemical defense system. And suggestions on the present research status of sugarcane insect resistance are put forward to provide references for the cultivation of sugarcane resistant varieties and the integrated pest control in sugarcane field.
