حصر مجتمع النيماتودا في حقول التبغ (Nicotiana tabacum L.)‎ صنفي برلي و فيرجينيا في الساحل السوري

Abstract EN

A study was conducted in both Burley and Virginia flue-cured tobacco fields to examine nematodes distribution along the Syrian coast (Lattakia, Jableh and Tartous) during the period 2011-2013, where 39 samples were collected from 32 fields.

Collected samples were examined under the microscope to determine the density of nematodes population and its frequency, and to identify the nematodes genera.

Thirty nematodes genera from twenty two families and seven orders were isolated from the soil and identified.

Based on their feeding habits, the identified genera were divided into five groups.

The results showed high nematodes population densities in all the fields studied, with a high percentage of plant parasitic nematodes which amounted to 50.19% in Burley tobacco fields and 55.33% in Virginia flue-cured tobacco fields, with significant differences between the two types of tobacco fields.

Meloidogyne spp.

was the most frequent with highest density compared with other plant parasitic nematodes genera in the studied tobacco fields of both varieties
