Sumitomo submits novel mosquito product for evaluation
Sumitomo Chemical has submitted a new insecticide for evaluation by the UN WHO Pesticide Evaluation Scheme (WHOPES) for adult mosquito control in indoor residual spray (IRS) programmes. The unnamed insecticide has a novel mode of action, Sumitomo points out. Only four classes of insecticide are recommended by the WHOPES for IRS and no new classes of insecticide for adult mosquito control have been introduced in the past 40 years, Sumitomo notes. That has given rise to some mosquito populations being resistant to existing insecticides. Extensive trials have shown that the newly developed insecticide is effective against "resistant and susceptible malaria transmitting mosquitoes under not only laboratory but also field conditions", the company states. It is said to be ideally suited for use in resistance management programmes.
