Population dynamics and distribution of the coffee berry borer, Hypothenemus hampei (Ferrari) (Coleoptera: Scolytidae) on Coffea arabica L. in Southwestern Ethiopia
Population dynamics and distribution of coffee berry borer, Hypothenemus hampei (Ferrari) (Coleoptera: Scolytidae) were studied on Coffea arabica L. in southwestern region of Ethiopia. Thirty coffee trees were sampled at weekly intervals from 2000 to 2001. Findings of this study showed that coffee berry borer population had a marked seasonal variation both on dry leftover and fallen coffee berries. Number of adult borers on dry leftover berries was significantly higher than on fallen berries (χ 2 = 3.89, P Key words/phrases : Coffee berry borer, Coffea arabica, Ethiopia, Hypothenemus hampei, population dynamics SINET: Ethiopian Journal of Science Vol. 27 (2) 2004: 127–134
