Abstract

Occurrence and distribution of 74 nematode species within 32 genera in West Bengal, has been reported as a result of a survey undertaken in four of ten agroecological regions of the State. Several species of each of Helicotylenchus, Hoplolaimus. Tylenchorhynchus. Pratylenchus, Hirschmanniella, meloidogyne, Tylenchulus Paralongidorus as well as Rotylenchulus reniformis are considered the most widespread and polyphagous. Many of these are considered to be associations new to science. This study along with the previous reports may now form the basis of a nematode advisory programmo in this State in which nematode problem is not yet realised in its proper perspective.
