灰飞虱室内大量繁殖及越冬饲养方法

A method of year-roundly mass rearing Laodelphax striatellus in laboratory

灰飞虱Laodelphax striatellus(Falln)作为多种植物病毒病的传毒介体,近年来发生数量呈逐年增加趋势,给水稻生产造成严重损失。杀虫剂室内毒力测定和抗性选育工作的顺利进行,必须长期饲养大量的标准试虫。文章介绍采用稻苗饲养室内大量繁殖灰飞虱的方法,饲养盒的使用使该方法更加方便,而越冬用麦苗饲养更接近田间的实际情况。

As the most important vector of some plant virus transmission,the populations of small brown planthoppers,Laodelphax striatellus（Fallén）（SBPH） were trended to increase in recent years,and it caused serious damage to rice plant.Thousands of standard larvae must be supplied in order to carry the research of toxicity bioassay and resistance selection.A rice seedling feeding method of mass rearing the small brown planthopper was presented in this paper.The use of feeding box makes the operation more convenient,and in winter feeding with wheat seedling is similar to the fact that the small brown planthopper on the wheat growing in the farmland.
