Fulvic, humic, acetic, N-bulyric, formic, lactic, and propionic acids were inhibitory to the survival or reproduction of Aphelenchus avenae, Aphelenchoides goodeyi, Helicotylenchus pseudorobustus, Meloidogyne hapla or Xiphinema americanum. Reproduction of H. pseudorobustus and M. hapla significantly increased with increasing amounts of muck added to sand, and with the initial amount of nematode...

The study was carried out to investigate plant parasitic nematodes in oil rose growing areas Isparta province July-August 2022. Soil samples were taken from 15 different and the with 65 samples. A total of 12 species determined study. These are Tylenchus spp., Aphelenchus Pratylenchus Dictylenchus Dorylaimus Paratylenchus Longidorus Xiphinema Meloidogyne Helicotylenchus spp. Merlinus (52.3%), (...

Nematodes of three genera (Acrobeloides sp., Aphelenchus avenae, and Scutellonema brachyurum) were induced to coil and enter anhydrobiosis in drying soil of two types: sandy loam and loamy sand. Coiling was studied in relationship to soil moisture characteristics. Coiling and the physiological state of anhydrobiosis occurred before the water in sandy soils reached a water potential of -15 bars....

Desiccation tolerance plays an important role in the overwinter survival of the foliar nematode Aphelenchoides fragariae. Survival rates of A. fragariae were compared with those of the anhydrobiotic soil-dwelling nematode Aphelenchus avenae after desiccation (90% RH), cold (4°C) and osmotic (500 mM sucrose) stress treatments. A. fragariae formed aggregates during desiccation and showed higher s...
