The present study was recorded the penetration rate, the migration% and the
distance covered by the species [(Steinernema riobrave, Steinernema sp. (S3),
Steinernema rarum, Heterorhabditids sp. (Hp2), Heterorhabditids sp. (Hp4) and
Heterorhabditids indica)]. In addition, the relation between these activities and the
lipid contents of each species were revealed. The authors found that, there are
considerable variations in migration rate between entomopathogenic nematodes
species and the migration is not affected by the original amount of lipid content in the
species. Species that have high lipid contents don't show high migration rate but the
infectivity was affected by the amount of lipid contents where the species contain high
lipid contents recorded high penetration rate of Galleria mellonella.
