摘　　要：An investigation of effect of Latana camara, Tephrosia vogelii and Zingiber officinale applied at 5%, 10% and 25% concentrations on flea beetle of cabbage was conducted on the Teaching and Research Farm of the Ladoke Akintola University of Technology Ogbomoso in the early seasons of 2011 and 2012. The experiment consisted of 11 treatments laid in a Randomized Complete Block Design （RCBD） with three replications. Data were subjected to analysis of variance and significant means were compared using the Least Significant Difference （LSD） at p〈0.05. All the tested plant extracts exhibited moderate efficacy in the control of flea beetle. The treatment plant extracts performed as well as synthetic insecticides （0.76±0.05 and 0.76±0.05, respectively）. It was discovered that 25% w/v of Z. officinale gave the best yield of 0.50 kg · hm-2. The result showed that extract of T. vogelii （0.71±0.00） and L. camara （0.96±0.23） could suppress flea beetle population at different hours of spraying, while Z. officinale showed an effect at 48 HAS （0.71±0.00） and 72 HAS （0.76±0.05） alter spraying.An investigation of effect of Latana camara, Tephrosia vogelii and Zingiber officinale applied at 5%, 10% and 25% concentrations on flea beetle of cabbage was conducted on the Teaching and Research Farm of the Ladoke Akintola University of Technology Ogbomoso in the early seasons of 2011 and 2012.
