Today a new forum topic was launched by Drs Derek Charlwood and Erling Pedersen from DBL in Copenhagen. They argue that pyrethroids should no longer be used for indoor residual spraying and be reserved for use on bednets. What's your opinion?
After all, they argue, its the only class of insecticides that can be used on nets at the moment. In support of the debate on this topic, let me add some questions here:
- Will it make a difference, in terms of resistance development, if pyrethroids will no longer be used for IRS and only on nets?
- Would banning of pyrethroid use in agriculture stop resistance development now that millions of treated nets have found their way into African homes?
- Is the combination of IRS and nets, both based on pyrethroids, speeding up resistance development?
- Will 'combination therapy', that is IRS based on non-pyrethroid insecticide combined with a pyrethroid-treated net be a better way forward?
- The chemical industry will not like the idea. Who should enforce the ban if it is considered worthwhile?
