The need for non-pyrethroid MoA active ingredient for IRS
Managing resistance to insecticides is one of the major issues facing the global fight against malaria. Resistance to at least one class of insecticides has been identified in over 75% of countries with on-going malaria transmission. The effectiveness of IRS is under threat due to the spread of pyrethroid resistance and the difficulty many countries find in rotating the class of insecticides they use year upon year, largely due to a lack of choice.
SumiShield™ 50WG is based on the neonicotinoid insecticide clothianidin. This was the first new MoA chemistry to be introduced to the vector control market in over 40 years. Following positive independent laboratory and field trials, SumiShield™ 50WG became the first vector control product evaluated and subsequently listed by WHO under the Prequalification (PQ) system.
SumiShield™ 50WG is odourless and trials show it has a low toxicity through skin contact and inhalation and is practically non-toxic to non-target organisms such as birds and fish.
How It Works
SumiShield™ 50WG has been designed as a single active ingredient formulation without a pyrethroid, thus making this formulation non-repellent. Pyrethroid and DDT treated surfaces hyper-activate resting mosquitoes causing them to be repelled. Mosquitoes are unaware of clothianidin alone and will rest for longer on treated surfaces and are more likely to die from exposure as they will absorb relatively large amounts of this insecticide. This increases effectiveness and reduces the opportunity for resistance to develop.
How to Use
SumiShield™ 50WG has been developed for IRS and can be sprayed on the inside of houses and residences, on walls and other surfaces that serve as resting places for mosquitoes. Delivered in small, easy to handle sachets, the product readily dissolves in water, with only one sachet required per tank, making transport simple and cost effective.
