Nematodes associated with pistachio in Sanliurfa, Turkey

Abstract

The study was conducted to investigate nematodes associated with pistachio grown in Sanliurfa, located in the Southeastern Anatolian region, between 2003 and 2005. Current status of plant parasitic nematode groups, as well as the density and distribution of important parasitic groups were included. Throughout the region, 50 different orchards were sampled in early summer. Soil samples of 100 grams were run for nematode extraction and nematodes were identified to the genera level. The following nematodes were found in the study with mean densities: Tylenchus, Filenchus, Helicotylenchus, Rotylenchus, Rotylenchulus sp., Pratylenchus, Pratylenchoides, Trophorus, Geosenamus, Tylenchorhynchus, Criconema, Paratylenchus and Xiphinema. Among them, Paratylenchus and Helicotylenchus were the most abundant and frequent groups, 205.7 and 62%, 34.1 and 46%, respectively. Pratylenchus, Xiphinema and Criconema were as follows in abundance and frequency, 5.7 and 16%, 3.7 and 18% and 0.8 and 2%, respectively.
