The World Health Organization Pesticide Evaluation Scheme (WHOPES) has issued a recommendation for a new polymer-enhanced, long-lasting Indoor Residual Spray for malaria vector control. This deltamethrin based spray was jointly developed by Bayer CropScience and IVCC (the Innovative Vector Control Consortium). It represents a viable cost-effective alternative to DDT for malaria control programs. Market introduction across Sub-Saharan Africa and other malaria endemic areas is expected to occur during 2014 once relevant national regulatory approvals are in place.
Since 2007, Bayer CropScience has been working with its partners in IVCC to develop longer lasting indoor residual spray formulations and new active ingredients to manage insect resistance in malaria vector control. The new polymer-enhanced formulation of deltamethrin offers a residual effectiveness of six months. The World Health Organization (WHO) has recognized this unique formulation as having a longer residual lifespan than any other pyrethroid insecticide formulation.
“The success of the international community’s goal of eradicating malaria globally depends ultimately on new ideas and innovation,” said Dr. David Nicholson, Head of Research & Development at Bayer CropScience. “Our long-lasting indoor-residual spray is an effective malaria intervention. As a global innovation and market leader in vector control, we will continue to work closely with IVCC to foster the introduction of new vector control tools for public health.”
“We are delighted to have met this important research milestone in our collaboration with Bayer CropScience”, said Nick Hamon, CEO of IVCC. “This collaborative achievement illustrates the progress which has been made on the original objectives to deliver effective and affordable vector control interventions. I look forward to further successful outcomes from the IVCC partnership with Bayer CropScience.”
There are many countries in Sub-Saharan Africa where the transmission period for malaria can be longer than six months. In these situations, when indoor residual spraying is regarded as an appropriate intervention, a product with longer-lasting efficacy can be very important, reducing the frequency of spraying required and saving considerable costs for malaria control programs.
All insecticide sprays for malaria control are required to be evaluated and recommended by the WHO for effectiveness and safety. Until now the only product formally recognized to have residual effectiveness exceeding six months has been DDT. However, as a Persistent Organic Pollutant (POP), the production and use of DDT is strictly restricted.WHO Recommends Syngenta’s New Long-Lasting Insecticide Formulation 26th November 2013
Syngenta and IVCC collaboration delivers new long-lasting insecticide formulation, Actellic® 300CS, now recommended by the World Health Organization to fight insecticide resistant mosquitoes.
Syngenta and IVCC are proud to announce that The World Health Organization Pesticide Evaluation Scheme (WHOPES) has granted a formal recommendation for the use of Actellic® 300CS in malaria vector control. The WHO recommendation opens up additional opportunities for more malaria control programs around the world to access this new long lasting insecticide formulation designed for the control of pyrethroid resistant mosquitoes.
Syngenta believes that people deserve to live their lives uninterrupted by mosquitoes and the diseases that they can transmit. Syngenta has a rich pipeline of insecticides and access to advanced delivery technologies and consequently has been providing leading edge solutions on mosquito control for decades.
Mosquitoes have evolved to survive a number of the existing control products and this threatens the effectiveness of disease prevention programs. IVCC is a product development partnership committed to working with industrial partners to accelerate the development and introduction of new tools to meet these challenges. Syngenta and IVCC have had a long standing collaboration to accelerate and enrich the innovation pipeline for mosquito control.
The development of Actellic 300CS was initiated in 2007, not only to control resistance to the pyrethroid class of chemistry, but also deliver longer lasting performance to facilitate greater program efficiency in spraying programs. Since then, the WHO Global Plan for Insecticide Resistance Management recommends the deployment of non pyrethroid products when programs are looking for technology to complement mass distribution of long lasting insecticide treated mosquito nets.
Syngenta used their expertise in microencapsulation technology to create Actellic 300CS, which is designed specifically for residual spraying. Numerous independent trials have demonstrated at least 9 months residual performance on a range of household surfaces, a significant improvement over current alternatives. Trials have also demonstrated control of pyrethroid resistant strains in both Anopheles and Culex species of mosquitoes.
This unique combination of controlling pyrethroid resistance with proprietary long lasting technology provides the opportunity for malaria control program managers have a greater impact on malaria as part of their integrated control program. Long lasting performance allows for reduction of spray program costs through moving to just one application per season whilst also managing pyrethroid resistance. This is essential when long lasting insecticide treated nets are currently dominated by this class of chemistry.
Actellic 300CS is the first commercial product to exit the IVCC pipeline, and this important WHO recognition meets one of Syngenta [MSB1] and IVCC’s commitments to provide access to new technology in disease endemic countries. More than a million people are now estimated to be protected by Actellic 300CS and production has been scaled up to support all key markets.
This development is just one step on the journey to develop new solutions to controlling mosquito-borne disease, and more alternatives are urgently needed, especially in the fight against growing insecticide resistance. Syngenta and IVCC continue to collaborate on the development of the next generation of insecticides, which will provide a robust solution to future insecticide resistance and equip malaria control programs with the tools they need to defeat malaria.

Listening and Learning at MIM 2013 10th October 2013
IVCC’s stakeholder event in 2013 took place at MIM in Durban, when key individuals and organisations from all over the world gathered to share information and strategies for fighting malaria.
One of IVCC’s key objectives for stakeholder events is to engage with people working in country control programmes. The MIM Pan-African Malaria Conference 2013 in Durban provided a perfect opportunity to make contact and learn from people in the front line of malaria vector control.
The IVCC stand provided a visual summary of key achievements since the launch of IVCC in 2005 and a time frame for delivery of new vector control tools.
There were many visitors to the stand. Most were seeking information about the progress of IVCC’s collaboration with industry partners to develop the three new active ingredients that will form the basis of a new generation of public health insecticides. A frequent question was, ‘how long before you can deliver?’, indicative of growing concerns about insecticide resistance.
Information about IVCC’s portfolio and details about insecticide resistance were presented to delegates in an IVCC symposium on new tools for the management of insecticide resistance.
Professor Hilary Ranson from LSTM started the IVCC symposium with an overview of insecticide resistance in vector control. Dr Charles Wondji looked at the mechanisms of insecticide resistance and Professor Diabate Abdoulaye considered current strategies and future challenges for malaria vector control in Africa. An industry perspective was provided by Frederic Baur, who outlined the development of new products for insecticide resistance management.
During an evening reception later in the week, the new IVCC CEO, Dr Nick Hamon, outlined the IVCC mission and objectives for the next few years. Tribute was paid to the founders of IVCC and thanks recorded to the committed industry partners and funders who make the work of IVCC possible.
IVCC also took part in a demonstration of the new Insecticide Quantification Kits (IQKs), which are designed to help spray programmes monitor the effectiveness of indoor residual spraying.
A long-time collaborator of IVCC and LSTM has been awarded this year’s Royal Society Pfizer Award for his malaria research. Dr Abdoulaye Diabate, who is investigating the mating systems of Anopheles gambiae, will receive £60,000 towards a study which aims to cut the mosquito’s high reproductive rate and thereby control the spread of malaria.
Dr Diabate, who is from Burkina Faso, was nominated for the award by LSTM’s Head of Vector Biology, Professor Hilary Ranson. Professor Ranson, who will be present at the award ceremony, said: “Dr Diabate is an exceptionally talented and creative vector biologist who is a thoroughly deserving recipient of the Royal Society Pfizer Award. His pioneering work on mosquito mating behaviour is opening up exciting new possibilities for controlling malaria and I am delighted that he now has the opportunity to pilot some of these ideas via the Pfizer Award.”
“We have collaborated with Dr Diabate on several occasions and the work that he will be able to carry out following this award, will have genuine benefits for all of us involved in trying to control the transmission of malaria.”
The new study, funded by the Royal Society Pfizer Award, will allow Dr Diabate to gather results on male mating behaviour that will be instrumental to the implementation of a full range of new malaria control tools / technologies, for example, engineered mosquitos and sterile insect techniques which rely on a good understanding of male biology.
Commenting on his prize Dr Diabate said: “The Royal Society Pfizer Award is such a wonderful and motivating award for African scientists. Not only does the prize boost high quality research in Africa by empowering African research institutes but in my specific case it will also allow me o quire the skills and knowledge that can help us win the battle against Malaria.”
Dr Diabate is the head of the medical entomology laboratory of the Institut de Recherche en Science de la Santé/Centre Muraz, Burkina Faso.
The Royal Society Pfizer Award is designed to reward scientists, based in Africa, at the outset of their career and to promote science capacity building in the developing world. It is awarded annually. The award, first made in 2006, recognises research scientists making innovative contributions to the biological sciences, including basic medical science.No Single Solution to Eradication of Malaria: Dr Alan Magill 18th June 2014
The current control paradigm for malaria is not sustainable in the long term from both a biologic and political perspective, said Dr Alan Magill, addressing the IVCC Stakeholder Day conference in Liverpool.
Dr Magill is a Director of the Bill and Melinda Gates Foundation charged with overseeing the development and implementation of strategies for the foundation’s ultimate goal of the eradication of malaria. He was addressing an audience of vector control and public health experts from across the world, who had gathered together to consider the latest developments in IVCC’s vector control programme. If malaria resurgence is to be avoided, Dr Magill said, eradication is the only strategy that makes sense moving forward.
He outlined five key principles in the malaria eradication strategy. Beginning with the first, precise definitions, he said, ‘the definition of malaria eradication is actually getting parasites out of people.’ The second and third principles involve complete clinical cure including removal of the ‘vast human reservoir of malaria parasites’ in asymptomatic people.
The fourth principle he outlined concerns the fundamental precepts of evolutionary medicine and correct ecologic thinking. ‘Malaria is a very big complex system. It’s got the biology, the ecology, the political, and the social pieces,’ he said. It is important to understanding it as a system and then ensure that product development and policies are ‘evolutionarily correct’ going forward.
Dr Magill’s final principle was think globally and impact locally, ‘there is no one size fits all, no one single solution that’s going to magically lead us to eradication,’ he said.
Talking about the role of vector control product development he said that it was important to accelerate the delivery of new vector control products through the current system and get them out to impact just as soon as possible.
‘Let’s finish the job,’ he said in conclusion. ‘We don’t like to get distracted by discussions about elimination and eradication. This is all about saving lives. It’s saving lives now in sick people and it’s saving lives for ever going forward because we’re going to avert all those deaths by elimination. It’s a pure simple equation. We know that this is biologically and technically feasible and we think the new tools that will be developed in the next few years will make a lot of the things we’re talking about much more operational and feasible.’
Turning to IVCC and the stakeholders in the room he said that the next decade would be an intense period of experimentation—’using current tools and new ways, and really thinking about that long term goal of eradication’.
‘IVCC is a hub in the eradication eco system, and through that hub we can reach out to all the talent in the room. I would say that if there’s a problem out there in the vector space world, well this is the group of people to solve it. You own it; if you don’t like it it’s up to you to change it.’
