The insecticidal and repellent activities of fruit extracts of Xylopiaaethiopica (Dunal) A. Rich. and Dennettia tripetala (Baker f.) G.E.Schatz belonging to the family Annonaceae was studied againstSitophilus oryzae (L.), an economic, primary post-harvest pest ofrice, and other cereal products. Infested rice grains (100 g) treatedwith 1, 2, 3, 4, and 5% (w/w) powders of both plants were evaluated fortoxicity against S. oryzae every 24 h for 3 d, and during F1 progenyemergence. The essential oils of both plants were also applied at 0.5,1, 1.5 and 2 mg cm-2 filter paper in Petri dishes for toxicitybioassays at 24 h exposure. Repellence bioassay with 10 μLsolution of essential oils on filter paper was performed in a Y-Tubeairflow olfactometer. Results indicate that powders of both plantssignificantly (P < 0.001) caused adult weevil mortality and areduction in F1 progeny emergence than the control. Essential oils werealso significantly (P < 0.001) adulticidal to S. oryzae after 24 hwith the highest dose (2 mg cm-2) producing 100% mortalityrespectively. Similarly, both male and female weevils significantlyavoided the test arm compared to the control arm in the Y-Tubeolfactometer repellence tests. These results suggest that X. aethiopicaand D. tripetala natural extracts have potential for use as part ofintegrated pest management of stored product protection against S.oryzae.
