It has been reported that the entomopathogenic nematodes including Steinernema carpocapsae, S. feltiae and Heterorhabditis bacteriophora when applied at rate of 2.5 billion infective juveniles/ha can cause 69- 94% mortality of first generation late instars of annual bluegrass weevil, Listronotus maculicollis. Of the 3 species of entomopathogenic nematodes, S. feltiae showed higher virulence against annual bluegrass weevil than the other two nematode species (see McGraw et al., 2010).
