摘  要:
室内研究黑尾叶蝉对不同水稻品种的选择性和选择机理。结果表明,视觉(寄主颜色)在黑尾叶蝉对寄主的定向选择中起着重要作用,采用Y形嗅觉仪测定黔优568、金优431、双穗雀稗对黑尾叶蝉的引诱性,黑尾叶蝉几乎不表现定向反应;T形仪生物学测定结果表明,光对黑尾叶蝉有迅速而明显的定向作用;黔优568较金优431对黑尾叶蝉的引诱作用强,双穗雀稗对黑尾叶蝉的引诱力不及水稻植株。在相同的光强下三基色的引诱作用较单色光强,田间粘虫板试验结果表明,绿、黄、蓝色的诱虫板较其他颜色诱虫板对黑尾叶蝉有较强的引诱作用。

摘  要:
Research on host selectivity and mechanism of Nephotettix cincticeps was conducted in door.Results showed that the vision(the color of the host) played an important role for host selection of N.cincticeps.By determining the attraction of Qianyou 568,Jinyou 431 and Paspalum with Y-tube olfactometer,it was revealed that N.cincticeps showed no direction selection.But according to the determining of the T-instrument,N.cincticeps made a fast obvious directional action movement toward the light source.It was showed that for the attraction of N.cincticeps,Qianyou 568 was stronger than Jinyou 431 and Paspalum was weaker than rice.Besides,tricolor light had the higher attraction of N.cincticeps than monochromatic light.Field experiments indicated that sticky traps of green,yellow,blue got higher attraction than other colors.
