Title: Negative impacts of scale insects and mealybugs infestation on mango leaf growth (leaf area) and pigments content at Esna district, Luxor Governorate, Egypt


M. M. S. Bakry belongs to Plant Protection Department as Faculty of Agriculture research center in Sohag Univ., Sohag, Egypt.


Studies were conducted to evaluate the negative impacts of scale insects and mealybugs on the morphological and chemical characters of mango leaves. Scale insects significantly reduced the area of infested leaves. Scale insects prefer younger leaves, causing significant loss in leaf areas and leaf pigment contents. The comparisons between different scale insects indicated that Insulaspis pallidula caused the greatest damage. The loss in the measured parameters was a summation of many factors including level of infestation, time of infestation and age of infested leaves.
