Atkinson, P.R. 1977 Preliminary analysis of a field population of citrus red scale, Aonidiella aurantii (Maskell), and the measurement and expression of stage duration and reproduction for life tables.. Bulletin of Entomological Research 67: 65-87.
Notes: A population of Aonidiella aurantii was studied on 72 Clanor orange trees in an orchard of 1800 15 year old trees growing at an altitude of 280 m at Tshaneni, Swaziland. This orchard had not been sprayed with toxic chemical for 18 months before observations started. Trees were banded with 'Formex' compound to control ants during the observation period. A method for making life tables is proposed, based upon the expression of stage duration and reproduction in terms of a physiological time-scale.
