线虫对农作物的危害,不仅表现在使作物生长发育停滞,发生畸变,而且也可能增加作物对其他病原微生物侵袭的易感性。此外,某些线虫还是植物病毒病的带病者。线虫对农作物的这些综合影响的结果是导致严重减产,造成经济上的重大损失,故不能不引起我们对线虫病害的重视。本文拟介绍一些有关农作物线虫的资料,供动物学教学工作者的参考。 Nematode harm to crops, not only in the crop growth and development stagnation, distortion, but also may increase the susceptibility of crops to other pathogenic microorganisms. In addition, some nematodes are also carriers of plant virus disease. As a result of these combined effects of nematodes on crops, which lead to serious cuts in production and substantial economic losses, we must not fail to draw our attention to nematode diseases. This article intends to introduce some information about crop nematodes for reference by zoology teaching workers.
