国际水稻研究所帕萨克、安德勒斯、加拉克噶克、拉洛斯等人,近年来曾对该所品种资源库中一万多个水稻品种通过田间、温室和实验室多种研究,探讨其对螟虫的抗性,总结出三种抗性机制,并筛选出八十余种可供进一步杂交利用的品种。现择要综述于下:在亚州为害水稻的螟虫有十几种,以螟蛾科的条螟(二化螟),黄螟(二化螟),白螟,黑头螟和夜蛾科的紫螟(大螟),对生产有明显影响。遭受螟害的水稻不仅产生枯心苗、白穗,而且降低水稻生长力,减少水稻分蘖,增加每穗不实率。这些螟虫都是由卵变幼虫,化蛹,羽化成蛾又产卵。在单季稻区各代出现,先后有别。在多季稻区则
In recent years, the International Rice Research Institute Pasaque, Andres, Galakarg and Lalos have conducted many researches on more than 10,000 rice varieties in the resource bank of the institute through fields, greenhouses and laboratories, Explore their resistance to stem borers, summed up three resistance mechanisms, and screening more than 80 varieties for further hybrid use. Now choose to summarize in the next: There are dozens of stem borers that damage rice in Asia, with the stem borer Pyralidae (Chilo suppressalis), yellow rice borer (Chilo suppressalis), white borers, black-headed borer and noctua Purple borers (Sesamia inferens), have a significant impact on the production. Rice damaged by stem borer not only produces dry seedling and white ear, but also reduces rice growth, reduces tillering of rice, and increases the rate of inbreeding per ear. These stem borers are from eggs to larvae, pupation, emergence and moth spawning. In the single season rice generation appeared, one after another. In the multi-season rice area then
