The study was carried out to evaluate the bioactivities of Hyptissuaveolens and Tephrosiavogeliileaves extracts (ethanol and distilled water as solvent) in the control of one of the insect pests of stored maize (Zea mays), the larger grain borer LGB (Prostephanustruncatus). Parameters studied include; contact toxicity by topical application, repellency, mortality, feeding deterrence (weight loss and seed damage)and F1 emergence. The ethanolic and aqueous extracts of Hyptissuaveolens and Tephrosiavogelii leaves were applied at the rates of (0.05, 0.1, 0.2, 0.3 and 0.5ml/10g of maize grains) at dosage level and (2.5, 5.0, 7.5, 10.0, and 15.0%) at concentration level and were replicated 3 and 5 times respectively in an experiment laid out in a Complete Randomized Design (CRD). Results obtained showed that all the treatments caused significant (P<0.05) toxicity, mortality, deterrence and repellency in adult beetles compared to the untreated control. Qualitative phytochemical screening was carried out and several phytochemicals were present in the extracts such as flavonoids, alkaloids, phenols, glycosides among others, leading to high potency of the extracts. Higher dosages had more effects on the mortality, toxicity and repellency of beetles and also had less weight loss and seed damage while lower dosages had less effects on mortality, toxicity and repellency of beetles and more weight loss and seed damage. Ethanolic extract of T. vogelii was observed to cause toxicity leading to 52% mortality while H. suaveolenscaused 42%. However, the ethanolic extract of T. vogeliiare the most toxic and produced the best effect with LC50 of 11.12% at 7 daysafter exposure and LD50 of 0.33ml/10g of maize grains at 7 days after exposure. Also, it is shown in the experiment that ethanolic extracts of the plants used are more potent than the aqueous extracts. T. vogelii ethanolic extract was more repellent (mean PR value = 70.50%) than H. suaveolens ethanolic extract(mean PR value = 59.50%).
