Abstract In this paper，we collected and analyzed the parasitic nematode species reported on related Amaranthaceae weeds at home and abroad on the basis of compiling the alien weeds of Amaranthaceae monitored in ports.The important alien weeds of Amaranthaceae included 5 genera and 32 species.Most of Amaranthaceae plants were important hosts of nematodes，and up to 11 species of nematodes infest Amaranthaceae plants，among which Meloidogyne were the most reported nematodes，and Amaranthus weeds were the hosts vulnerable to nematode infestation in Amaranthaceae plants.
