Abstract


The insecticidal potency of a local plant Hyptis spicigera (Labiatae) was evaluated against Aedes aegpti larvae and adults alongside conventional insecticides 0-2,2 dichloroving 0.0 dimethyl phosphate. The air dried leaf extracts obtained using soxehlet extractor were applied to the fourth larvae instar of Aedes aegypti larvae obtained from blood fed adults mosquitoes caught from the Jos metropolis. Hyptis spicigera produced 81. 33% and 100 % mortality for the larvae and adult respectively at a concentrations of 100mg/l which compete significantly P<0.05 with the convention 0-2, 2 dichlorovinyl 0.0 dimethyl phosphate (p<0.05).The implication and usefulness of the finding are herein discussed.
