Toxicity and repellency properties of different mixtures of Xylopia aethiopica and Tithonia diversifolia against Nasutitermes were assayed by taking three combinations (100% X. aethiopica (T1), 50% X. aethiopica + 50% T. diversifolia (T2) and 100% T. diversifolia (T3) and control (T0). After 24 hour fermentation of plant materials, T3 consistently caused significantly lowest percentage mortality at 1–24 hour after treatment (HAT). T1 was not significantly different from T2 in mortatiy at 1, 6 and 24 HAT which ranged from 11.07–45.53%. T1 caused the highest percentage repellency (66.67).
