摘　　要：冬季室内人工饲养灰飞虱时,良好的饲料植物是保障灰飞虱正常生长、繁殖的重要前提。针对冬季室内饲养中饲料植物常发生白粉病,偶尔混有蚜虫的问题,进行了饲料植物选择与病虫防治试验。结果表明,健壮无病、具有一定茎秆的小麦和稗草苗适于成虫取食、产卵和卵的孵化;幼嫩小麦苗和稗草不仅是灰飞虱若虫喜食的饲料,还可以有效控制白粉病的发生;喷施20%三唑酮乳油可有效控制小麦白粉病的发生;对饲养过程中混杂的小麦蚜虫,应在移虫箱内利用灰飞虱的趋光特性及时进行人工精心挑选去除。Healthy rearing plants for Laodelphax striatellus Fallen in indoor artificial feeding was the key factor affecting the growth and reproduction of the insect ,which is the main vector to transmit several important viruses infecting crops of rice ,maize and wheat. It is the base of further studies on the viruses to have the vector in mass. In this paper,it was reported that the wheat and barnyardgrass （Echinochloa crusgalli Beauv. ） plants with about 10 cm straw were the most favorable plants for the adults,because they were suitable for the adults to feed ,lay eggs ,and egg hatching as well. Young plants of the wheat and the grass were the best to feed the nymphae. Alternative using wheat and the grass could avoid the contamination of wheat powdery mildew,which was very likely to occur in a greenhouse with suitable temperature and humidity. Aphid contamination should be avoided through carefully checking in a vector transferring cage with extra light.
