Rice root aphid, Rhopalosiphum rufiabdominale (Sasaki), is a cosmopolitan species widespread in North America. Most records of this insect are of its association with roots of grasses and sedges, but known hosts also include numerous broadleaved plants both grown outdoors and in greenhouses. Indoor grown Cannabis sativa L., particularly when intensively grown for marijuana production, has also emerged as a common host for this insect in the United States and Canada. On this crop, it has an anholocyclic life cycle where it is almost entirely found in association with plant roots. Colonization of new plants is largely by alate forms that may emerge from soil in large numbers as plants near maturity.

大麻作为水稻根系蚜虫的主机（半翅目：蚜科）在北美

稻根蚜虫Rhopalosiphum rufiabdominale（Sasaki）是在北美广泛分布的世界性物种。该昆虫的大多数记录都与草根和莎草有关，但是已知的寄主还包括许多在室外和温室中种植的阔叶植物。在美国和加拿大，室内种植的大麻，特别是在集约化种植大麻生产时，已普遍成为这种昆虫的寄主。在这种作物上，它具有完整的生命周期，几乎完全与植物根系相关。新植物的定殖主要是在植物接近成熟时从土壤中大量出现的新陈代谢形式。
