摘      要：Anopheles gambiae is a vector that is responsible for the transmission of malaria parasites which causes high morbidity and mortality in Nigeria and the world at ***-vector contact can be reduced by the use of conventional repellents being sold in the market,though some of these repellent are not environmentally friendly and *** have developed resistance to some of these *** this end,the phytochemical constituents and insecticidal activity of crude extracts of Hyptis suaveolens(bush mint)was determined on adult *** mosquitoes collected from Lafia,Nasarawa State,Nigeria to evaluate its effect in controlling ***,70%ethanolic and diethyl ether fat crude extracts were made from *** dried leaves and used to carry out the *** phytochemical screening of the ethanol extract revealed the presence of alkaloids,flavonoid,saponins,tannins,steroids and reducing *** was not detected in the ethanol *** steroids was detected in diethyl ether extract the rest of the phytochemical tested were *** larvae were collected from the field and were raised to F1 progeny adults that were used for the *** protocol for carrying out human bait repellency cage test was *** hand treated with the extracts was exposed to a cage containing 30 female mosquitoes for each of the extracts *** ethanolic crude extract treatment proved to be more effective in repelling mosquitoes with 0%(0/30)mosquito landing than diethyl ether extract which had 40%(12/30)mosquitoes landing and the control hand(untreated left hand)had the highest landing rate 63.3%(19/30)which showed very high significant difference(χ^(2)=27.2619,df=2,P0.00001)in relation to the *** 24 hours holding period,the mortality rate of exposed mosquitoes was observed to be highest in the ethanolic treatment 73.3%(22/30).In conclusion,*** extracts have repellency potential in controlling adult ***.
