Abstract
The present work targeted to evaluate the role of entomopathogenic P. lilicanus fungus in overcoming the major okra sucking pests besides the side effect toward their predator.The targeted entomopathogenic fungus was cultured on Sabouraud dextrose yeast agar and prepared three Serial dilutions concentration suspensions to test their efficacy toward Aphids under laboratory and field conditions, while leafhopper was tested under field condition only.
            The obtained results were cleared that the high concentration 1x108 spore/ml, caused the best mortality percentage toward Aphis gossypii after 7 days of post-treatment. While under field conditions, the treatments were caused reduction ranged between 72.7% and 63.0 % toward A. gossypi population and 88.7%%, 86.7 % in leafhopper population, respectively. On the other side, the predators' population (F/coccinellidae) was also affected due to reducing the population of their prey.
