Record of the rice cyst nematode, Heterodera oryzae in Kerala, India.
Samples collected from banana and rice fields near Panchayat Public Well in Karanagappally Quilon district, Kerala, India in 1984 recorded the presence of cyst forming nematodes on roots of both crops. Detailed examination of the population with paratypes confirmed its identity as Heterodera oryzae. H. oryzae could be distinguished from H. oryzicola by its body length and the hyaline tail terminal length of its second stage juveniles. It is likely that the population on banana and rice in Kerala could be a mixture of H. oryzae and H. oryzicola.
