Determination of repellence potentials of some aqueous plant extracts against okra flea beetles Podagrica uniforma

Abstract

Laboratory experiment was conducted to ascertain the repellence potentials of some aqueous Plant extracts against okra flea beetles (Podagrica uniforma). Six treatments namely: Ten percent aqueous extracts of Piper guinneense (schum and Thonn), Azadirachta indica A Juss, Xylopia aethiopica (Dunal) A. Rich, Garcinia kola (Heckel), Aframomum Melegueta (Rosch) K.schum and control (Distilled water) were assessed using a completely Randomized Design (CRD) replicated three times. The results showed that 10% aqueous extract of Piper guineense and Azadirachta indica had the highest percentage repellence values (100%) while control (Distilled water) had the least value (0%). Hence, 10% aqueous extracts of Piper guineense and Azadirachta indica could be used as repellents in the control of okra flea beetles. © JBiopest.
