稻水象甲(Lissorhoptrus oryzophilus Kuschel)滞育征候群中的飞行行为

１９９４－１９９６年对浙江省双季稻区稻水象甲（ＬｉｓｓｏｒｈｏｐｔｒｕｓｏｒｙｚｏｐｈｉｌｕｓＫｕｓｃｈｅｌ）飞行行为的研究表明，稻水象甲飞行扩散的行为特征是：（１）长时间的起飞准备和不高的起飞成功率，每晚的迁出率只有三分之一左右，（２）卵巢，飞行肌呈季节性消长而无局地飞行（ｔｒｉｖｉａｌｆｌｉｇｈｔ）；（３）飞行速度不高，飞行能力不强，且风力稍大便无法起飞，一般情况下不会形成远距离自然扩散，因此

Flight behaviour in the diapause syndrome of the rice water weevail, Lissorhoptrus oryzophilus Kuschel

The studies on the flight behaviour of rice water weevil(RWW), Lissorhoptrus oryzophilus Kuschel,in the double rice cropping area of Zhejiang Province from 1994 to 1996 were presented.As one of the symptoms in their diapause syndrome,the weevils displayed unique characteristics of their flight behaviour:a long time limbering up excercise at the tip of grass (or rice) leaves before take off,but a low exodus rate(ca.one third);there was no trivial flight in their life history because their flight muscles ...
