 ABSTRACT

The reniformis nematodes of the genus Rotylenchulus (Haplolaimidae: Nematoda) are sedentary semi-endoparasites of numerous crops. There are ten species out of which R. reniformis and R. parvus are important, and three species (R. amanictus, R. clavicadatus, R. leptus) are monophagous: two on monocots and one on Rosids. In general, Rotylenchulus species are capable of feeding from very primitive Magnoliids to plants of advanced category. Preference was distinctly observed towards the plants in Rosids (42.779%) followed by monocots (23.949%) and Asterids (21.755%). The SAI values were also higher for these groups of plants. The study on lineages further revealed intimate affinity to febids (25.594%), followed by commelinids (18.647%), malvids (16.088%), lamiids (11.883%), and campanulids (9.141%). Poales contribution within commelinids was 65.353%. Maximum affinity of Rotylenchulus species was observed by their association with plants from  families Poaceae (7), followed by Fabaceae (6), Malvaceae (6), Asteraceae (4), Oleaceae (4), Soanaceae (4) and so on.
