Abstract

Study of plant parasitic nematodes associated with faba bean in Khuzestan province, southwestern Iran.

Abstract

Root and soil samples were collected and examined from faba bean (Vicia faba L.) fields in Khuzestan province, southwestern Iran. Seven nematode species were identified as follows: Ditylenchus dipsaci, Ditylenchus medicaginis, Geocenamus bavaricus, Geocenamus brevidens, Geocenamus nanus, Geocenamus nothus and Hoplolaimus seinhorsti. Morphometrics and light micrography were provided for the studied species and their differences with those given in their original descriptions were discussed. Populations varied in their frequency and distribution among surveyed faba bean fields but G. brevidens was the most commonly observed species. This is new record of D. dipsaci, D. medicaginis, G. bavaricus, G. nanus and G. nothus for nematodes fauna in Khuzestan province. G. bavaricus, G. nanus, G. nothus and H. seinhorsti are reported for the first time in association with faba bean in Iran. This is the first report of G. brevidens and G. nanus from roots of faba bean.
