/ˌɒlɪˈɡɒfəɡəs/
Some caterpillars are oligophagous and feed on only a few related plants.
一些毛毛虫是寡食性的,只取食少数几种有亲缘关系的植物。
Although the beetle is oligophagous, it can shift among several host species when its preferred plant becomes scarce, which complicates pest management.
尽管这种甲虫是寡食性的,但当偏好的植物变少时,它仍能在几种寄主之间转换,从而使害虫防治更复杂。
来自希腊语构词:**oligo-**(“少、稀少”)+ -phagous(“吃……的”,源自 phagein “吃”)。字面意思就是“吃得很少种类(食物)的”。
