Preliminary Survey of Nematodes Associated with Vegetables Crops in Western Libya

Abstract

The coastal region from Khoms to Zawia was surveyed for nematodes. Samples from different fields were collected and processed using the sieving and gravity techniques. Recovered nematodes were killed in hot water and fixed in F.A.A. Besides root-knot nematodes (Meloidogyne incognita and M. javanica). the most common plant-parasitic nematodes found were: Tylenchorhynchus spp.. Pratylenchits spp.. Zygotylenchus spp., Merilinus spp., Tylenchus spp.. Additionally, Dorylaimus spp., Eudorylaimus spp. and Xiphinemella spp. were recorded but their impact on potato and tomatoes is not known. Several free living nematodes such as Acrobeloides spp., Acrobeles spp.. Diplogaster spp., and Rhabditis spp. were also found.
