Abstract
Over the past years, the utilization of entomopathogenic nematodes (EPNs) has grown exponentially making entomophatogenic nematology as one of the growing fields in crop protection and as promising, eco-friendly alternative for insect pest management. Using Ostrinia furnacalis-bait technique, an EPN population was isolated from soil samples collected from San Ramon, Zamboanga City, Zamboanga del Sur [Philippines]. Morphological observations baed on general diagnostic characters of the infective juveniles (IJs), first generation females and males, insect cadaver properties and molecular characterization using the 16S and 28S of the ITS region of the rDNA led to its classification under the genus Steinernema. Based on the average IJ length (492.25 +- 85.14 mum), and the wide spicule head exhibited by the males, this EPN shows resemblence to the members of the S. carpocapsae group. However, molecular data suggests that it is a novel species.
