DA  aCharacterization of Mesocriconema species associated to Grapevine Decline Disease in Southern Brazil.h[electronic resource]  c2023  aOnline First.  aThe grapevine decline disease (GDD) is a complex disease that causes substantial losses in grape production. Ring nematode (Mesocriconema xenoplax) is frequently detected in symptomatic vineyards. Unfortunately, this nematode is frequently mis-identifed due to its similarities with other species of this genus. In this study, the hypothesis was tested that there is a species complex of Mesocriconema associated with GDD in southern Brazil. This hypothesis was based on a previous result that identifed diferent Mesocriconema species in vineyards in southern Brazil including M. xenoplax, M. curvatum, M. rusticum, M. sphaerocephalum, M. ornatum, and another seven undefned species, using only morphometric data. This current study provides the frst characterization of Mesocriconema species associated with GDD, their distribution, and variability, through the use of morphological and molecular analysis in an integrative approach.  aMesocriconema xenoplax  aNematóide  aDoença do declínio da videira1 aDIVERS, M.1 aCORREIA, G.
