Abstract

Our survey conducted to study the distribution and abundance of plant parasitic nematodes associated with different vegetation in Shoubra El-Kheima. Nematode infection had not been surveyed before in this area. The data showed the presence of ten plant parasitic nematode genera, which were: Meloidogyne sp., Helicotylenchus sp., Criconema sp., Pratylenchus sp., Rotylenchulus, Tylenchorhynchus sp., Tylenchulus, Paratylenchus sp., Tylenchus sp., and Xiphinema sp. Nematodes were extracted by using modified burmman funnel and identified using identification keys. Results showed that Meloidogyne was the most common plant parasitic nematode. Data demonstrated that, 10 genera of plant parasitic nematodes were recorded to be associated with the examined crops. The highest and lowest frequency of occurrence (FO %) of nematodes in vegetable hosts were represented by Meloidogyne and Paratylenchus (26.0% and 10.5% respectively). While, the genera Criconemella, Xiphinema, and Tylenchulus didn't record in the examined vegetable plants. On the other hand, data of fruits recorded that: Highest and lowest Fo% of nematodes were Meloidogyne and Criconemella (53.3% and 7.8% respectively). Ornamentals showed that, highest FO% was Meloidogyne (27.0) and lowest was Tylenchus and Tylenchorhynchus equally (1.7). Conclusion: Meloidogyne, and Pratylenchus were the widest genera in distribution. Moreover, tomato, grapes, and Ficus carica were highly susceptible.
