Abstract:
Residents in irrigated urban agricultural sites face numerous mosquito problems
such as increased mosquito populations and reduced insecticides susceptibility due to the
creation of mosquito breeding sites and agricultural use of insecticides and hence require
effective protective products against them. In this study, the protection effectiveness of
three pyrethroid formulated mosquito coils of Malaysian origin against Anopheles gambiae
sensu lato from an irrigated urban agricultural site in Ghana were evaluated for their potential
use. Sucrose fed An. gambiae s.l. were exposed to insecticide-containing coils in a 70 cm x 70
cm x 70 cm glass chamber to assess the insecticidal effect of the coils. The 0.005% metofluthrin
coil caused the most rapid knockdown of 50% of the test mosquitoes. The mean lethal effect
of the coils on An. gambiae s.l. were as follows; 0.005% metofluthrin (86%), 0.3% d-allethrin
(74.33%), 0.15% d-trans allethrin (72%) and the 0.25% d-allethrin reference coil (69%). The
0.005% metofluthrin coil achieved the highest insecticidal effect on An. gambiae s.l. compared
to the other coils and hence performed better than the others as an anti-mosquito product. All
the three test coils were effective against An. gambaie s.l. from the irrigated agricultural site
compared to the reference coil.
