On the association of some plant parasitic nematodes with cork wood tree, Duboscia myoporoides and remarks on abnormalities in males of Meloidogyne incognita

Cork wood tree, Duboscia myoporoides is being reported as a new host of Meloidogyne incognita, Pratylenchus coffeae, Helicotylenchus imperialis and Tylenchorhynchus digitatus. Seedlings grown in pots showed stunted growth in the presence of root-knot nematode. Die-back symptoms were observed under field conditions when all the four nematode genera were present in the rhizosphere. Male intersexes of M. incognita with vulva in the middle of the body or outgrowth on ventral side in anal region, were encountered.
