ABSTRACT

Entomopathogenic nematodes (EPN) are one of the promising alternatives to synthetic insecticides for the
control of insect pests. For successful insect management, EPNs must be established in the soil and
remain infective, persistent and pathogenic for long periods. The present study investigated on the
emergence of Steinernema feltiae infective juveniles (IJ) from infected Galleria mellonella cadavers in
moist and dry conditions. A significantly high number of infective juveniles of S. feltiae emerged in moist
conditions as compared to dry. A positive correlation was found between the weight of the Galleria
larvae at infection and the numbers of IJ recovered in the moist as compared with dry conditions.
