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.
