Badawi, A.I., & Al-Ahmed, A.M.N. 1990 The population dynamics of the oriental scale insect, Aonidiella orientalis (Newstead) and factors affecting its seasonal abundance.. Arab Gulf Journal of Scientific Research 8(3): 81-89.
Notes: Summary/abstract in: Arabic. Abstract: Based on random samples of leaves taken about twice per month from four Ficus nitida trees; counts of living scales made on 1 sq. inch per each leaf surface; population at lowest level in summer; first peak of abundance at beginning of winter; temperature negatively and significantly correlated with population; sides of trees exposed to wind usually harbored smaller population.
