Abstract
The pine woolly aphid, Pineu pini (L.) is currently regarded as one of the most serious pests of exotic pines in Kenya. Odena (1972) has described the basic life history of this pest, but 'its impact on Pinus is essentially unknown. Its distribution is widespread in Kenya, as well as in Rhodesia. The first sign of damage is stunted needles, followed by abortion of buds. The effects of repeated attacks are cumulative so that growth reduction, tree deformity and at times 'outright tree mortality are encountered.
