Entomopathogenic nematodes (EPNs) have been used as biological control agents for control of various agro-forest insect pests, and are especially effective against soil-dwelling insect pests. Effect of soil moisture on pathogenicity of commercial EPNS for white grub control was evaluated in laboratory, pots, and golf courses. Pathogenicity of EPNS in sand column was variable depending on depth, soil moisture, and golf courses. Pathogenicity of EPNS in sand column was variable depending on depth, soil moisture, and EPN species or strain.
