Aphelenchoides microstylus n. sp. and Seinura onondagensis n. sp., a nematode predator, are described from dead Scots pine (Pinus sylvestris L.) in Onondaga County, New York. Females of A. microstylus are 370 to 485 microm long. The body is slender and tapers posteriorly to an amucronate, pointed terminus. The head is continuous with the body, and lips bear a stylet guide. Diagnostic characters...

Abstract Three known species, Aphelenchus avenae , Ditylenchus myceliophagus and Tylenchorhynchus aduncus (Rhabditida, Tylenchomorpha), are described from sand coastal dunes in Spain associated to the rhizosphere of xerophilic plants. A. is characterized by having stylet with 16–22 µm long, pharyngeal dorsal gland overlapping intestine, postvulval uterine sac about 2.5 times body diameter, fema...

A total of 211 soil samples were collected in different crop fields from 10 districts. Out samples, 137 diagnosed for plant parasitic nematodes. The the cruciferous and solanaceous crops. All together twelve nematodes identified. identified genera are Meloidogyne, Helicotylenchus, Pratylenchus, Tylenchus, Tylenchorhynchus, Hoplolaimus, Belonolaimus, Criconemoides, Aphelenchoides, Hirschmanniell...

Soil nematodes are major soil organisms known to reduce wheat production worldwide. However, they a crucial part of biodiversity. Due the limited data available regarding nematode biodiversity associated with cereal crops in Morocco, survey was conducted 2019 across 80 fields. Thirty-three taxa were obtained different trophic groups: 11 bacterivores (i.e., Rhabditis and Cephalobus spp.), herbiv...

The effects of abamectin B1, diazinon, and methiocarb insecticides on Aphelenchoides fragariae and Ditylenchus dipsaci in Lamium maculatum, Phlox subulata, Rhododendron indicum, and Begonia x tuberhybrida were determined in a series of greenhouse experiments. Abamectin at 0.005 or 0.011 g a.i./liter (0.3 or 0.6 ml/liter Avid 0.15 EC), diazinon at 0.62 or 1.87 g a.i./liter (2.6 or 7.8 ml/liter K...
