Background With the rapid spread of pyrethroid resistance in the main malaria vectors from
Benin and the various resistance mechanisms involved (metabolic resistance and knock-
down resistance (kdr), it is important to foresee effective resistance management strategies.
Thus, the knowledge of the insensitive acetylcholinesterase (ace-1 R) effects on phenotypes
of An. gambiae will help us to strengthen basic and operational research on thedevelopment
of strategies that will use organophosphates or carbamates as alternatives against …

0%. Carbamates (bendiocarb) and organophosphates (fenitrothion and pirimiphos-methyl)
have maintained their efficiency against A. gambiae Dassa-Zoume and Zogbodomey
populations. Carbamates (bendiocarb) and organophosphates (fenitrothion and pirimiphos-
methyl) have proven to be powerful alternatives against pyrethroid resistant malaria vectors
such as A. gambiae Dassa-Zoume and Zogbodomey populations. The use of any of these
three compounds in the centre Benin would be successful in malaria vector control.
