NEW YORK, 22nd September 2014 – Only 4 classes of insecticide are currently recommended by the World Health Organization Pesticide Evaluation Scheme (WHOPES) for indoor residual spraying (IRS).  No new classes of insecticide for adult mosquito control have been introduced in the past 40 years.  Since there is widespread and growing resistance to many of these compounds, especially in Sub Saharan Africa, malaria control programs have had very limited control options.

Sumitomo Chemical is therefore very pleased to announce the development and recent submission to WHOPES of a new mode of action insecticide product for adult mosquito control for application in IRS programs.

Extensive trials have confirmed the efficacy of this product against both resistant and susceptible malaria transmitting mosquitoes under both laboratory and field conditions.  As this product has a different mode of action chemistry from currently available interventions, it is also ideally suited for use in resistant management strategies and will therefore help preserve the effectiveness of existing vector control tools.

It is anticipated that this product will help combat the very real and growing threat of insecticide resistance and will complement the other vector control tools in the Sumitomo Chemical range, that include Olyset® Net, Olyset® Plus, SumiPro® and SumiLarv®.

“Sumitomo Chemical is once again delighted to be at the forefront of innovation in vector control by contributing to the fight against malaria and other vector borne diseases. We are confident that this new chemistry will have a significant impact in combating insecticide resistance – while at the same time improving people’s lives,” said Ray Nishimoto, Managing Executive Officer, Health and Crop Sciences Sector, Sumitomo.
