Steinernema feltiae Filipjev, S. glaseri Steiner and Heterorhabitis indica (Poinar, Karunakar, David) developed and reproduced in sugarcane shoot borer, Chilo infuscatellus Snellen and Chilo sacchariphagus indicus (Kapur) larvae infected with granuloviruses (GV). The mean percent infectivity of the three nematode species showed no significant difference among the diseased and healthy larvae of both shoot and internode borers. The multiplication of dauer juveniles was significantly higher in healthy larvae of C. infuscatellus and C. sacchariphagus indicus compared to GV infected larvae.
