Abstract: | Previous studies have been made on the relative efficacy of the eight possible stereoisomers of allethrolonyl chrysanthemate. Some of these compounds and their mixtures have been classified according to their knockdown activity against Aedes aegypti. Two techniques were used, the contact method recommended by WHO and the method described by Katsuda and Ogami to study the effect on mosquitoes of the smoke from burning coils. Results show that on Aedes aegypti, the relative knockdown activity of the various stereoisomers of allethrin was about the same with both methods. The d trans chrysanthemate of d allethrolone (S-Bioallethrin) was the most effective. |
