Finding an insecticide formulation that retained many of the desirable qualities of pyrethroids is vital to IVCC’s mission. Given the importance of vector control and the growth in resistance to pyrethroids, Sygenta’s non-pyrethroid formulation, Actellic CS, could not have come at a more opportune time.
Unlike previous non-pyrethroid formulations that were only effective for two to three months, Actellic CS has demonstrated residual activity of nine to twelve months in IVCC sponsored trials. The formulation has also proved to be more effective on challenging surfaces such as traditional mud used in rural African communities.
Actellic CS became commercially available in 2012 and is currently being used in five countries, with adoption of the insecticide expanding as countries seek resistance management solutions.
Current estimates are that over one million households have already been protected. Furthermore, early monitoring and evaluation data indicate that there has been a significant impact.
Like many public health tools in developing countries, cost is a major factor in a product’s sustainability and ability to protect lives of people in developing communities. The release of Bayer’s long-lasting Deltamethrin formulation, K-Othrine Polyzone is a step towards IVCC’s goal of finding alternative more cost effective insecticides.
In laboratory trials it has shown a residual effect of 12 months on concrete and wood surfaces and nine months on mud surfaces. This is a significant increase from previous formulations which will, consequently, greatly reduce operational costs. The new formulation can also be used in rotation with non-pyrethroid insecticides, a validated method for combating insecticide resistance.
K-Othrine Polyzone has been commercially launched for IRS and is currently being successfully used in Kruger National Park, South Africa.
