In: Egyptian Journal of Biological Pest Control 2007.v.17(2)Summary: Effect of the initial infection densities (15,100 and 1000 IJs) on the quality of the produced juveniles of two nematode species, Heterorhabditis bacteriophora ( H.b) and Heterorhabditis indica (H.i) was studied The number of the initial penetrated Us was increased by inc,oasing in infection density of the two species. Us length and width measurements correlated negatively with the three levels of infection. The penetration rate of (H.b) was negatively related to the initial infection density while the opposite was evident for (H.i). Insignificant differences were found in the virulence of (H.b) juveniles produced from the three levels of infection while for (H.i) a significant increase was found between the juveniles produced from levell, II and that of level III.
