Abstract

The present study was aimed to evaluate the efficacy of Eucalyptus camldulenis L. leaves and barks alcoholic extracts in three concentrations (1.25,  2.5and 5%)  against cowpea beetle Callosobruchus maculatus (Fab.), which was monitored 24 and 48 hours after treatment. The result showed that the highest effective mortality  of  the leaves and barks extracts were obtained with the concentration 5 gm.ml-1  after 24 and 48 hours  reached 60.00 % and 80.00 % respectively, and the lowest effective  mortality of the leaves extract was 36.67% and 66.67% respectively after 24 and 48 hours  at 1.25 gm.ml-1. The attract rate of insect was 9.5 in concentration 5 gm.ml-1  and 3.66% at 1.25 gm.ml-1  compared to an expulsion rate amounted 23.5% at 5 gm.ml-1  and 21.83 at 2.5 gm.ml-1 respectively for leaves and barks.
