摘要
对浙江省双季稻区稻水象甲（ＬｉｓｏｒｈｏｐｔｒｕｓｏｒｙｚｏｐｈｉｌｕｓＫｕｓｃｈｅｌ）起飞行为的研究表明，风是影响其迁飞扩散的重要因子。稻水象甲起飞前需要较长时间（１～２ｈ）的展翅准备，因而风力稍大便无法起飞。其自身的飞行能力不强，一般情况下不会形成远距离自然扩散。因此，应严格控制人为传带以延缓其蔓延速度。
Studies on the takeoff behaviour of rice water weevil ( Lissorhoptrus oryzophilus Kuschel) indicated that the weevils took more than 1h to display their limbering up exercise at the tip of grass (or rice) leaves before takeoff, so that their exodus rate were affected strongly by wind and they could only take off at calm or breezing weather. Therefore, the long distance spread of rice water weevil would be retarded if the artificial conveyance was controlled effectively.
