Abstract: This study was to determine the effectiveness of Moringa (Moringa oleifera Lam) extracts in controlling insects and mites on tomato plants. The study was conducted in Cape Coast in the Central Region of Ghana Three different concentrations of Moringa oleifera leaf, bark and root as well as water and a chemical insecticide were used in spraying tomato plants. Treatments were applied on plots of land laid in randomized complete block design. Insects and mites found on the tomato plants were observed at between 7 and 11 am every six days on each sub-plot and the number counted. Graphs were drawn and interpreted. Means were compared with analysis of Variance. Results showed that there were significant differences among the treatments (p<0.05) but insignificant for concentrations as well as between treatments and concentrations (p>0.05). Synthetic insecticide was the most effective against all the species studied. Reduction of species populations were treatment and concentration dependent. In all, Moringa root extract appeared to be the most promising in controlling four of the species studied. It is suggested that further research using Moringa extracts in reducing species numbers be carried out using higher concentrations of the extracts. Furthermore, the mechanism of the effect of the extracts in reducing the species populations should be studied.
