Efficacy of four new entomopathogenic nematode strains including Heterorhabditis indica strains MP17 and MP111, Heterorhabditis sp. strain MP68 and Steinernema minuta strain MP10 from Thailand was tested against the second instar larva of the Japanese beetle, Popillia japonica in laboratory bioassays. This study demonstrated that the strains of both H. indica and Heterorhabditis spp. were more efficacious against P. japonica that the strain of Steinernema minuta. However, when comparisons were made among the strains of Heterorhabditis nematodes, MP111 strain of H. indica was the most efficacious against the second instar larva of Japanese beetle . Read following paper on the virulence of entomopathogenic nematodes from Thailand on Japanese beetle.
