Preliminary investigations of the pests of exotic forest trees in Zambia.

Abstract

This paper reports the insects which were collected from exotic forest trees in Zambia during the period 1973-1975, and reviews previous records. The insects which cause most damage, namely the cerambycid beetles Phoracantha recurva and P. semi-punctata, are reported at greater length with descriptions of their life-history, host-range and associated predisposing factors. The occurrence of these pests is discussed in relation to their economic importance.
