Knockdown and mortality rates of susceptible <i>Anopheles gambiae</i> s.s. post contact with community used Alpha-cypermethrin long lasting nets.

M0, M1, M2, M3, M4, M5: month 0, month 1, month 2, month 3, month 4, month 5; KD60: knockdown rate of mosquitoes 60 minutes post contact to treated material. KD60 and mortality rates for interceptor nets remained very during the 5 month trial except on month 3when tested nets were found very dirty. With Fendona SC long lasting treated nets, the KD60 and the mortality rates were slightly but significantly lower than those recorded with Interceptor nets (p<0.05).
