The nematode Scutellonema bradys is the main phytosanitary problem of yam (Dioscorea rotundata) in the Brazilian State of Bahia. Little is known about the host range of this nematode in Brazil, especially on weeds and plant species cultivated together with yam. This study aimed at evaluating different plant species to determine their host status to S. bradys and to study the relative infectivity of different stages of the nematode on selected host plants. Among the 48 evaluated plant species, 12 were infected by S. bradys. Yam was considered to be the only good host of the nematode, while Luffa algyptiaca, Momordica charantia, Heliotropium indicum, Vigna unguiculata, Cucurbita pepo, Abelmoschus esculentus, Sicana odorifera, Solanum lycopersicum and Ipomoea batatas were classified as bad hosts because of the relatively low reproduction factor as compared to yam. Crotalaria juncea and Cajanus cajan behaved as trap plants because large numbers of S. bradys penetrated their roots but populations decreased over time. Our results showed that juveniles are more infective than females and these are more infective than males on roots of five host plants. We also demonstrated that S. bradys prefers certain host plants as inferred by their lower reproduction on roots of these hosts. Penetration of juveniles tended to be spread over 16 days after inoculation, whereas for adults it was more concentrated at 8 days after inoculation. These results may be important to plan crop rotation schemes to control the yam nematode.
