Abstract |
The present study aimed to study the 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). The number of the initial penetrated IJs was increased with increased infection density for the two species. IJs 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 reverse 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 level I, II and that of level III. A significant decrease in storage ability was found after 45 days for the juveniles of (H.b). Also, a decrease was found between 15 and 30 days of storage for the juveniles of 100 and 1000 levels of infection. For (H.i), a significant decrease in storage ability was observed after 15, 30 and 45 days for the juveniles produced from the three levels of infection. A decrease in the host finding ability of the juveniles produced from the three levels of infection of (H.b) was obtained. The reverse was obvious in (H.i) with the same trend.
