An integrative approach to the study of (Nematoda: Hoplolaimidae) Colombian and Brazilian populations associated with crops.

In total, 10 populations of associated with spp., six from Colombia, and four from Brazil were identified to the species level. Morphological and morphometric data were recorded for each population, performed a principal components analysis (PCA), a conglomerate, along with consensus sequences of D2 to D3 expansion segment of the large subunit of ribosomal DNA (28S) for different populations.

Morpho-molecular characterization of Colombian and Brazilian populations of associated with spp.

Three populations, two from Colombia and one from Brazil, of associated with banana and plantain, were characterized using morphological, morphometric, and molecular methods. Morphometric data from these populations were similar to type and reference populations of . Partial sequences of both D2-D3 rDNA and mitochondrial cytochrome oxidase subunit I (COI) regions had a strong affinity (99% similarity) to previously published sequences of .

A Rapid Diagnostic for Detection of Aphelenchoides besseyi and A. fujianensis Based on Real-Time PCR.

Aphelenchoides besseyi and A. fujianensis have been frequently found in mixed populations associated with forage grass seed in Brazil. The morphological similarity between both species has previously led A.

Molecular identification and phylogenetic analysis of Metarhabditis blumi (Nematoda: Rhabditida).

The species Metarhabditis blumi was diagnosed for the first time in Brazil using a molecular assay. Parasites isolated from two cattle herds from the state of Minas Gerais, southeastern Brazil, were classified as M. blumi according to their D2/D3 expansion fragments of the 28S rDNA sequence, which had a high degree of homology (100% similarity) with a M.
