摘　　要：稻水象甲(Lissorhoptrus oryzophilus(Kuschel))在贵州稻区危害面积逐年加大,局部地区暴发成灾。为了明确水稻旱育秧技术对稻水象甲的实际控制效果,分别设置单独水秧、单独旱秧以及水秧和旱秧混合栽种3种方式,连续两年观察稻水象甲越冬代成虫在3种栽种方式的水稻秧苗上取食、产卵情况。研究发现稻水象甲成虫在水秧和旱秧上都能取食,但是仅在水秧上产卵,连续两年在单独旱秧和混合旱秧上平均产卵量均为0。因此旱育秧技术是一项可以有效阻隔稻水象甲繁殖扩散的防控技术。Lissorhoptrus oryzophilus（Kuschel） spread rapidly in Guizhou and break out in some area. In order to evaluate the control effect of dry-rice-nursery technology on L. oryzophilus,we observed feeding and ovipositional of L. oryzophilus on three rice seedling forms（watered-seedling alone,dry-rice-nursery alone,watered-seedling and dry-rice-nursery together） for two years. Our experiments showed that L. oryzophilus could feed in water rice and dry rice,however,it could only la y eggs in the water rice,but it can＇t lay eggs and no larva was found in the dry rice and mix dry rice. Therefore,dry-rice-nursery could be used as effectively technology for L. oryzophilus breeding control.
