Abstract
The study confirmed the occurrence of oriental yellow scale insect Aonidiella orientalis (Newst.) in a large number of citrus orchards in the central region of Iraq and estimated the severity of infestation at different locations. Sour orange twigs infestation level was 100, 45 and 80%, the leaves 78, 36.2 and 55% and the fruits 45.0, 20.5 and 30.2% in Baghdad, Dialaa and Wasit, respectively. The insect did not have any effect on citrus in Karbalaa and Al-Najaf governorates. The presence of the soft scale insect Coccus hesperidium L. was also recorded on citrus trees in few numbers, but without economical damage. The survey also recorded the presence of oriental yellow scale insect on fruit trees and ornamental plants and bushes. There was a significant statistical variation in the total population density on different citrus species, with 7.41, 4.30, 3.41, 2.77, 1.09 and 1.07 insect/in2 on Grape-fruit, sweet lemon, sour lemon, sour orange and orange, respectively.
