Four distinct peaks, representing 4 annual generations (2 winter and 2 spring) were observed in populations of the diaspidid Aonidiella orientalis on Ficus nitida in Saudi Arabia in 1987-88. Populations were lowest in summer, probably due to very high temperatures and arid conditions. Temperatures (maximum and mean) were negatively and significantly correlated with populations, relative humidity was slightly positively correlated, and rainfall had no apparent effect.
