Abstract

Growing for a period of 24 weeks after being infested with pine woolly aphids, Pinus patula seedlings lost 12.2 and 14.1 per cent diameter and height growth respectively, compared to uninfested seedlings. Reduction in dry weight biomass production amounted to 27.8 per cent for the roots and 20.9 per cent for the shoots and stems.
