使用合成性诱剂捕捉器来调查田间甘薯小象甲比其他方法,既准确又省事,一般性诱剂的引诱力随浓度的增大而越强,超过了某界限,反而降低,作性诱剂的载体以橡胶隔板为好,其用量以 Img 为宜.诱捕器的形状以广口瓶型的引诱力最好,水盘型和粘着型其次.但以用途不同各显所长.诱捕器以设置在地面为佳.引诱距离和时间与捕获率都有一定的关系.根据其特性探讨该虫的诱杀防治是很有前途的.
The use of synthetic attractant traps to investigate the field sweetpotato a smaller than other methods, both accurate and easy to save, the general attractant lure with the concentration of the stronger and stronger, beyond a certain limit, but lower, for the lure It is advisable to use a rubber separator for the carrier of the agent, and it is advisable to use it in an amount of 1 mg. The shape of the trap is best for the juggernafe, the water tray type and the adhesive type, It is better to set it on the ground.It has a certain relationship between the lure distance and the time and the capture rate.It is very promising to study the trapping and killing of this insect according to its characteristics.
