In the more humid coastal areas of the country this Aleurodid has for many years been a serious pest of the crop. Apart from sucking the sap of the leaves, honeydew excreted by this species supports growth of the "Black Sooty Mould" fungus which renders trees and fruit unsightly and interferes with photosynthesis. In 1958 a survey carried out in the coastal areas of Kenya revealed that although some small degree of control was exerted by Coccinellid predators, no internal parasites occurred.enhttp://creativecommons.org/licenses/by/3.0/Journal ContributionCitrusHumid zonesPestsSucking insects
