RUEDA PUENTE, Edgar Omar et al. Identification and population dynamics of plant parasitic nematodes associated with the halophyte Salicornia bigelovii (Torr.) in northwest Mexico. Rev. Mex. Cienc. Agríc [online]. 2015, vol.6, n.4, pp.707-720. ISSN 2007-0934.

Related to the characterization of plant parasitic nematodes halófita Salicornia bigelovii (Torr.) In northwestern Mexico, studies are zero, which motivated this research to the isolation and characterization of nematodes associated with Salicornia. Two systematically sampled in ten locations in two areas (Puerto Peñasco and Bahía de Kino, Sonora), which develops naturally in the halophyte study was developed; samplings were made at intervals of two months for 11 months corresponding to the phenology of the plant. Sampling depth levels of 0-50 and 50-100 cm was considered to study the nematode population. The collected samples were processed to homogenize the sample and taking subsamples of 500 g; subsamples were processed by sieving and centrifugation; aliquots for fication and identification were collected. Were collected and identified eight genera of plant parasitic nematodes; including the most abundant were Tylenchus, Helicotylenchus, Merlinius and Criconematidos. Their populations varied in relation to the ecotype, soil type, soil depth and season.
