The Yam Nematode, Scutellonema bradys, a New Threat to Potato
Potato Research, 2015We investigated the possible threats of Scutellonema bradys on potato production by evaluating the host suitability and damage symptoms in five potato varieties grown in Europe and Africa. The probability of nematode entry, spread and establishment in Europe was also investigated, through a pest risk analysis (PRA).

Canadian Journal of Zoology, 1984
Scutellonema cephalidum n. sp., a parasite of the rubber plant, Ficus elastica 'Decora,' is described and illustrated. Its primary distinguishing characters are the irregular size and shape of four to nine segments of the basal head annule, parthenogenetic females which lack a spermatheca, and distinctiveness of the cephalids, hemizonid, and ...

PRESENCE OF THE YAM NEMATODE Scutellonema bradys IN GUADELOUPE AND MARTINIQUE
1986The "root-lesion nematode" (Pratylenchus coffeae) has been, until 1985, the major soil-borne pest of yam crops in the French West Indies. Since early this year, the actual "yam-nematode" has been found regularly in tubers sampled in Guadeloupe and Martinique.

The Mechanism of Action of the Yam Nematode, Scutellonema Bradys
Nematologica, 1976Chromatographic analysis of the incubation solution of S. bradys showed that five amino acids--aspartic acid, phenylalanine, hydroxyinol acetic acid, leucine and isoleucine were discharged by this nematode. Pectinase and amylase activities were detected in homogenates of S. bradys.

Systematic Notes On Some Species of Scutellonema Andrassy, 1958 (Hoplolaimidae: Nematoda)
Nematologica, 1984Three species of Scutellonema are removed from the genus: S. picea is considered a junior synonym of Rotylenchus robustus; S. petersi is considered a junior synonym of S. indorobustus ; S. sexlineatum is regarded species incertae sedis. S. naveenum is synonymized with S. magniphasmum. S. ramai, S. sheri and S. orientale are considered identical with S.

Scutellonema bradys and Pratylenchus spp. associated with weeds in yam fields
Nematology, 2019Summary Dry root disease of yam (Dioscorea spp.), caused by Scutellonema bradys, Pratylenchus coffeae and P. brachyurus, is prominent among the plant disease problems of yam in Brazil. In order to evaluate the association of these nematode species with weeds, field sampling was performed during 2016 and 2017 in yam-growing areas with a history of the ...
