Background: Phenacoccus solenopsis (Tinsley) and Icerya seychellarum (Westwood) are the most important sucking insect attack several important economic crops around the world. Also, it secretes what is known as honeydew on the surfaces of the infested leaves of plants, which provides a fertile medium for the growth of black rot fungi that hinders the photosynthesis of these plants. Finally, the infestation by these species leads to losses in both quantity and quality of the crop. Materials: These compounds were (Biosect (3.2 X 10 6 spores/mg) and Biover (3.2 X 10 4 spores/mg)), the two compounds contain Beauveria bassiana (Balasamo). Also used Silica gel where add Biosect with Silica gel ratio (2:1 & 1:1), Biosect: Silica gel. The concentrations used were 3.2 X 10 4, 3.2 X 10 5 and 3.2 X 10 6 spores/mg of Biosect and add silica gel by ratio 2: 1 and 1:1 Biosect: Silica gel from concentration 3.2 X 10 6. The concentrations used were 3.2 X 10 2, 3.2 X 10 3 and 3.2 X 10 4 spores/mg of Biover. Results: that efficiency of tested Entomopathogenic fungi against Phenacoccus solenopsis nymphs and adults under laboratory conditions: In nymphs % mortality ranging between 26.22 - 80 %. In adults and Percent mortality ranging between 6.66 % to 96.66 % at the concentration (3.2 X 104 spores/ ml.) of Biosect. In nymphs Percent mortality ranging between 10 – 97.0 %. In adults Percent mortality ranging between 35.22 - 100% at the concentration (3.2 X 104 spores/ ml.) of Biover. Also, at the concentration (3.2 X 104 spores/ ml.) of Biosect + Silica, % mortality of nymphs ranging between 55.22 - 100 % and in adults % mortality was 46.66 -100%. While on Icerya Seychellarum nymphs and adults under laboratory conditions. In nymphs % mortality ranging between 10.0 - 76.9%. In adults Percent mortality ranging between 3.22 - 66.88 % at the concentration (3.2 X 104 spores/ ml.) of Biosect, in nymphs Percent mortality ranging between 9.44 - 100 %. In adults Percent mortality ranging between 9.44- 95.0 % at the same concentration of Biover and in nymphs % mortality ranging between 29.0 - 100 %. In adults % mortality was 15.44 - 100% at the concentration (3.2 X 104 spores/ ml.) of F.+ Silica. During okra season 2022, Biosect+ Silica gel (1:1) was the most potent compound in reducing the population density of the P. solenopsis nymph and adult after three days (84.38 and 100% reductions of nymph and adult, respectively), after 7 days, the reductions were 93.07 and 100% with an average of 95.53% and provided an overall average of 91.74%. Biover (3.2 X 104 spores/mg) were the least effective compounds, where overall average reduction ratios were 75.90 %.
