Abstract
Some biological and ecological aspects of certain scale insects in citrus orchards at Qualubia and Fayoum governorates are reported. The dominant scale insect in Qualubia is Lepidosaphes beckii while in Fayoum is Aonidiella aurantii. Both scale insects have four generations per year. Climatic conditions have great infleunce on population variability and distribution. Generally, the scale insects (either adult or nymph) prefer the central part of the tree especially in spring and summer seasons.
