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 take-off behavior of Lisorhoptrusory zophilus Kuschel in double cropping rice in Zhejiang Province show that wind is an important factor that affects its migration and spread. Asiatic weevils need a long time (1 ~ 2h) for the wings to get ready for take-off, so the wind is slightly stubborn and can not take off. Its own flight capability is not strong, under normal circumstances will not form a long-range natural proliferation. Therefore, people should be strictly controlled to slow their spread.
