The evaluation of synthetic insecticides,biopesticides and two concentrations of mineral oilsto control the Maskell scale insect,Insulaspis pallidula (Green) and mealybug,Icerya seychellarum (Westwood)on mango trees was conducted at Esna district, Qena Governorate, Egypt. Admiral was the most effective treatment againstI. pallidula, followed by Challenger, Biover, Bioranza, Chemi oil 2% and Chemi oil 1%. Bioranza and Biover were highly effective treatments against I. seychellarum, followed by Challenger, Admiral, Chemi oil 2% and Chemi oil 1%.The mineral oil was the least effective in controlling either of the two pest species and doubling the concentration of mineral oil did not significantly enhance its performance. The synthetic insecticides (Admiral and Challenger) and the biopesticides (Bioranza and Biover) were effective in controlling the scale insects. The greatest effectiveness of these products was observed four weeks after application.
Key words: Scale insect, mealybug,control,mango trees.
