Efficacy of Trigonella foenum-graecum on third stage larvae and adult fecundity of Anopheles pharoensis

The insecticidal activity of Trigonella foenum-graecum [fenugreek] against the larval maturation and adult emergency of An. pharoensis 3 rd stage was evaluated under controlled laboratory conditions. Concentrations of 100%, 70%, 50%, 25%, 5%, 2%, 1%, 0.9%, 0.7%, 0.5% and 0.3% showed 100% larval mortality rate. 0.2% and 0.1% caused mortality of 88.9% and 66.7% respectively. On the other hand, the fecundity of emerged adults was zero% and 33.3%. However, one control larvae died and the nine emerged adults were fertile. So, it was recommended to be use in controlling larvae of An. pharoensis
