前言在热带稻作区,褐稻虱被列为最应警惕的害虫之一。根据国际水稻研究所试验场内所设置的光诱器对褐稻虱诱杀量的年度变化情况看,褐稻虱由于水稻品种和栽培习惯的变化而成为常发性害虫,而且可以看做是和抗虫品种不断拮抗过程的一个实例(见图1)。对褐稻虱的抗性,应是丰产品种必须具备的生理特性之一。特别是为害抗虫品种的生物型的出现,正促使人们对品种抗性的深入研究。本文就水稻品种对褐稻虱的抗性机制以及与抗虫现象密切相关的褐稻虱的取食习性作一概述。
Preface In the tropical paddy area, brown planthopper is listed as one of the most should be vigilant pests. According to the annual changes of the trapping rate of the brown planthopper in the experimental plant set by the International Rice Research Institute, the brown planthopper is a common pest due to the change of rice varieties and cultivation habits, and can be regarded as An example of an ongoing antagonism of insect resistant species (see Figure 1). The resistance to brown planthopper should be one of the physiological characteristics that must be possessed by high-yielding varieties. In particular, the emergence of biotypes of pest-resistant varieties is prompting people to conduct further studies on variety resistance. In this paper, the resistance mechanism of rice cultivars to BPH and the feeding habits of BPH closely related to insect resistance were summarized.
