The present study was conducted to determine the comparative efficacy and bioactivity of aqueous extracts of four botanicals (leaf, root bark, flower) under in vitro condition. Cypermethrin 1% G was used as standard check and untreated control against maize stem borer in maize (Zea mays L.), during 2012 at Ambo Plant Protection Research Center, Ethiopia. The treatments were aqueous leaf extract of Nicotiana spp. L. and Cymbopogon citratus, root bark aqueous extract of Securidaca longepedunculata F., and flower extract of Chrysanthemum cinerariaefolium at 5% concentration. The cumulative data revealed that the standard check-Cypermethrin 1% G at rate of 0.3 kg/ hectare recorded significantly higher mean percent mortality of maize stem borer, Busseola fusca, over all the other treatments. Among the botanical extracts, C. cinerariaefolium and C. citrates 5% concentration was recorded higher efficacy mean mortality (75 and 58.33), respectively, against B. fusca within three days, and found to be at par with some of the other botanical extracts. The Nicotiana spp. leaf extracts and S. longepedunculata root bark extract showed significantly lower efficacy mean mortality.
