Bio-efficacy of Risasi Electric Mosquito Mat Against Anopheles Gambiae Anthropophilic Malaria Vectors

The bioefficacy of mats prallethrin group of synthetic pyrethroid was studied against laboratory strains of Anopheles gambiae s.s..  This synthetic pyrethroid was evaluated against worn alone and work sock with DEET. Protection efficiency was highest 99.8% in Trap with Slow releasing mat, 92.5% in worn sock sprayed with DEET(20% active ingredient) and least (8.6%) in Trap with worn sock alone. The slow released mosquito electric mat has shown a very high protective efficacy than standard repellent DEET. A worn sock alone showed the normal mosquito attraction trend for all trapping hours which could be indicator of mosquito biting for unprotected group.  This study have shown Mats deterred 99.8% of the mosquitoes from been trapped on the CDC light trap for 10 hours. The use of these formulations as a control tools in reducing man-vector contact is important in controlling residual malaria transmission. In the light of these findings, a synthetic have shown to be efficient in indoor and enclosed outdoor environments against malaria and other biting mosquitoes in Tanzania.
