Six genera of culicines mosquitoes are known as vectors of several diseases such as yellow fever, dengue and filariasis. Insecticides are commonly used in controlling these vectors either through impregnated nets or by spraying. Susceptibility status of culicine to three different insecticides in Gombe metropolis was carried out between the months of march and may 2011 using the WHO protocol. A total of 1500 Adult female culicines were used for the tests. Mosquitoes from Gombe State University showed 96%, 63%, and 66% susceptibility to Alphacypermethrin (0.75%), Bifenthrin (0.15%) and Bendiocarb (0.1%) respectively. The mosquito samples from Dawaki quarters indicated 92%, 62% and 69% susceptibility to Alphacypermethrin, Bifenthrin, and Bendiocarb respectively; whereas culicines from New market Area showed susceptibility of 90% to Alphacypermethrin, 44% and 69% to Bifenthrin and Bendiocarb respectively. No full susceptibility to any of the chemicals was observed; however, percentage mortality to Alphacypermethrin in all the sites suggests the possibility of resistance that needs to be confirmed but results for Bifenthrin and Bendiocarb indicates resistance of the mosquitoes in all the study sites. In view of this, it is important to implement insecticide resistance monitoring strategy in Gombe State.
