Results of studies indicated that the grape fruit and bitter orange were the most preferred host in term of adult's attraction and egg laying. The first spring peak of egg with an average of 116.2, 102.1 egg / 25 leaf respectively occurred in April. While the fall peak of the insect and egg laying was observed on sweet lemon at average 54.24 egg/25 leaf. The egg laying on bitter orange tree average of 161 egg / 25 leaf in the same month. During the season 2009 the adult laid the higher rate of egg on bitter orange tree with an average 161/25 leaf. While the Winter peak of the insects and egg laying were recorded on lemon tree and sweet lemon with an average of 946.6, 929.8 egg /25 leaf respectively. The predator Chrysoperla mutata was the most dominating on bitter and citric lemon trees. The results of this study were discussed in term of providing information to develop an integrated management program to control this pest in Iraq.
