| Abstract | ||||
| 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. | ||||
