| Abstract | ||||
| The migration and the dispersal of five entomopathogenic nematode infective stages had been studied in column of sandy soil under laboratory condition. It was found that it differ according to some factors, these factors included comparison between the effect presence or absence of the insect host Gallaria mellonella and Spodoptera littoralis, insect feces, the nematicide (Nemacur), and host species. The nematicides improved migration and average net distance of all tested nematode strains, except the Steinernema glaseri strain, with which a remarkable inhibition in its mobility, was obviously, observed. Feces of S. littoralis increased the migration rate and the dispersal than the host itself. Most nematode strains were attracted to S. littoralis more than to G. mellonella larvae. | ||||
