Arboviruses transmitted by mosquitoes such as Dengue, Zika, Chikungunya and Yellow fever, represent a major threat to public health worldwide. The Global Vector Control Response (GVCR) recently adopted at the WHO assembly aims to reduce the burden and threat of vector-borne diseases by 2030 through effective locally adapted sustainable vector control. The evidence base to support effective vector control is however limited for arboviral diseases due to a lack of vector surveillance and by the emergence and spread of insecticide resistance in mosquito vectors.


A recent systematic review highlighted that 40 countries already reported resistance to at least one chemical class in the mosquitoes Aedes aegypti or Ae. albopictus. Resistance is now recognized as a major threat for the control of arboviral diseases and has likely contributed to their re-emergence and spread in some parts of the world. Important knowledge gaps remains on mosquito resistance including its distribution, dynamics, mechanisms and its impact on vector control. Furthermore, there is an urgent need to review progress and achievements made in the deployment of integrated approaches and/or innovative technologies for the surveillance and control of arbovirus vectors and to discuss their potential for mitigating insecticide resistance.

Aim of the conference

Organized jointly by the French Institut de Recherche pour le Développement (IRD) and Duke-NUS Medical School of Singapore, the conference will serve as a forum for addressing the progress, research gaps and priorities for the control of vectors of emerging arboviruses and the management of insecticide resistance. The conference has been labelled ‘‘France-Singapore Year of Innovation 2018".

The conference aimed at facilitating the involvement of scientists, stakeholders, members of the private and public sectors, and decision makers from around the world to share knowledge and ideas and to provide recommendations for the improvement of insecticide resistance surveillance and deployment of innovative vector control tools.

Objectives of the conference

> To update the global burden of arbovirus diseases and spread of their vectors worldwide

> To review the current knowledge on the distribution, levels and mechanisms of insecticide resistance

> To understand the operational implications of resistance and detail the options for management when strategies fail

> To review the performances of new technologies and strategies for the control of invasive vectors and their potential for mitigating insecticide resistance

> To foster private-public partnership for the development of new insecticide products for vector control

Expected outcomes

The conference is expected to raise awareness for strengthening the capacity of national authorities in resistance monitoring and deployment of alternative tools for arboviral diseases control. The conference will focus on basic and translational research with the scope of enhancing vector control and fostering innovation. Round tables open to all participants will be set up to leverage the knowledge of the audience into strategies that may accelerate the translation of vector research into policies and programs.

A follow up of the 1st WIN conference, Rio de Janeiro, Brazil

The first international conference on Insecticide resistance in vectors of arboviruses, held in Rio de Janeiro, Brazil, from December 5 to 8 2016, aimed to identify strategies for the development and implementation of standardized insecticide resistance management and to define research priorities for control of vectors of arboviruses. Representatives from 94 institutions working on vector-borne diseases were present including research institutions and universities, international organizations (WHO), development agencies (USAID), ministries of health and members of the private sector.

Supported by the WHO Research & Training program on Tropical Diseases (TDR), the Departement of Neglected Tropical Diseases (NTDs) and the US Center for Disease Control and Prevention (CDC), the first WIN conference attracted more than 160 participants of around 30 different nationalities and, was followed by 70,000 people on the web. The workshop proceedings of the 1st WIN conference were published in Parasites and Vectors.
