dc.description.abstractThe seasonal cycles of Eriosoma lanigerum (Homoptera: Aphidiae) and its natural enemy, Aphelinus mali (Hymenoptera: Apelinidae), were studied in the Western Cape Province region of South Africa. Crawlers of E. lanigerum migrated from the roots into the apple trees during spring to initiate above-ground colonies. Population numbers peaked at the end of summer. Aphelinus mali became active from February until June. Eriosoma lanigerum numbers declined with the onset of winter but a few colonies remained on apple trees during winter.
