Neodolichorhynchus phaseoli, Pratylenchoides crenicauda, P. erzurumensis, P. utahensis, Scutylenchus paniculoides, Trophurus impar and Tylenchorhynchus variann...

two species of pratylenchoides recovered from the grasslands in sabalan region and one species recovered from natural habitats of tehran are illustrated based on morphological, morphometric and molecular characters. the first species, p. crenicauda is characterized mainly by its lip region with three-four annuli, lateral field with four incisures areolated throughout the length and having rod s...

Plant parasitic nematodes were systematically surveyed in cereal production areas of Isparta and Burdur Provinces Turkey 2016-2017. Nine plant nematode genera identified [Ditylenchus (23%), Geocenamus (20%), Helicotylenchus (33%), Heterodera (<1%), Meloidogyne (3%), Pratylenchus (76%), Pratylenchoides (52%), Paratylenchus (41%) Tylenchus (18%)]. spp. was found 82% 68% samples, 55% 63% samples P...

Pratylenchoides camachoi n. sp. from rosemary (Rosmarinus officinalis L.) in Sierra De Cazorla in southeastern Spain is described and illustrated. Pratylenchoides camachoi n. sp. is a bisexual species characterized by a cylindroid, sometimes clavate-shaped, male tail with a uniquely shaped smooth, rounded terminus. Females are characterized by a short esophageal overlap and six lines in the lat...

Pratylenchoides sheri n. sp., a bisexual species from the Pacific coastal area of California, is described and illustrated. Its most distinctive characters are the esophageal glands slightly overlapping the intestine dorsally, the large ventrally slanting esophago-intestinal valve, the lack of labial sectors in the first lip annule, the presence of males, and apparently functional spermatheca. ...
