Nematode species composition and ecology of some plants from the Cucurbitaceae Juss. family

This article presents scientific findings on the diversity, distribution, feeding strategies, and ecological characteristics of nematodes associated with cucurbit crops belonging to the family Cucurbitaceae Juss. , specifically watermelon ( Citrullus vulgaris Schrad), melon ( Cucumis melo L.), and pumpkin ( Cucurbita moschata ). The study also evaluates the significance of key parasitic species affecting these crops. As a result of the research, 49 nematode species were identified, belonging to 5 orders, 21 families, and 31 genera. Analysis by taxonomic group revealed that the orders Dorylaimida , Rhabditida , and Tylenchida were dominant, while Monhysterida and Araeolaimida were represented by fewer species. When analyzed based on host plants and soil texture, 46 species were recorded in watermelon grown on light loamy soils, 32 species in pumpkin cultivated in medium loamy soils, and 27 species in melon grown on heavy loamy soils. Among the identified nematodes, 22 species were found to be common to all three plant species, while several species were specific to certain soil types.
