菜豆象(大豆象)Acanthoscelids obtectas Say是我国对外植物检疫对象之一。只是近几年开展废旧船检疫中,截获到它的机会较多,如1982—1986年福州口岸进口38条废旧船中,带有菜豆象疫情的船只共有9条。1986年1月我们从“日尼亚”上截获到活的菜豆象,并进行了饲养。据观察,菜豆象的生活习性与四纹豆象、绿豆象等在寄主、产卵、一龄幼虫,危害特性等方面有很多不同之处,所以在检疫检验时有很多值得注意的地方。
Bean (Elephant Soybean) Acanthoscelles obtectas Say is one of the objects of foreign plant quarantine in our country. Only in recent years to carry out quarantine of used ships, intercepted it more opportunities, such as 1982-1986 imports of Fuzhou Port 38 abandoned ships, with beans as the epidemic of a total of nine vessels. In January 1986, we captured live beans from “Niya” and kept them. It has been observed that the habits of bean lobster have many differences in aspects such as host, spawning, first-instar larvae, harmful characteristics and so on. Therefore, there are many notable places in quarantine inspection.
