while H. bacteriophora caused only 17.5 % mortality. The authors mentioned
that the low effect of H. bacteriophora could be interpreted as this species was
isolated from a tropical area, therefore it was not adapted to low prevailing
temperatures. Such findings confirm the importance of the biological and
ecological characteristics of the EPN applied, since soil is the natural habitat of
EPN and most of the successful control with EPNs was achieved against soilinhabiting
insects (Georgis, 1990).
In conclusion, soil application of EPNs could be recommended as a
biological tool for RPW control, within a durable IPM strategy. Persistance after
release is a fundamental property of any biocontrol agent, in view of its practical
exploitation. Steinernema abbasi and H. indicus, sprayed in a field study around date
palms, survived in the treated soil for at least 1 year (Abbas & Mousa, 2003).
