The IRAC Mode of Action Working Group have developed a set of 74 slides as a MoA tutorial outlining the major mechanisms of insecticide resistance and, explaining with graphics, MoA by the targeted physiology affected using the broad categories of: Nerve and Muscle, Growth and Development, Respiration, Midgut and Unknown or Non-specific target sites or functions….
A video from CropLife International and the Insecticide Resistance Action Committee (IRAC) that explains the importance of mode of action as the basis for effective and sustainable resistance management to preserve the utility and diversity of available insecticides and acaricides. The video can be viewed in English or watch it in Spanish, Mandarin or Portuguese….
The new IRAC leaflet has been designed in conjunction with CropLife International providing growers with essential information on insect resistance management and the significant benefits for growers. The leaflet is in English at the moment but an editable version will be available shortly so that it can be translated into the local languages and targeted for specific countries and sectors….
The Tomato Leafminer Tuta absoluta is a pest of great economic importance with high reproduction capabilities and short generation life cycle which makes it at risk of developing resistance. The pest has spread from L. America, where there is already resistance to a range of MOA groups, to Europe, the Middle East and N. Africa. Using the Tuta absoluta poster IRAC is taking pro-active steps to advise on key management strategies to evaluate and reduce the spread of resistance….
Global Plan for Insecticide Resistance Management in Malaria Vectors is the title of a report released by the UN World Health Organization which contains the latest available evidence on the extent of insecticide resistance around the world, and puts forward a strategy for global and country levels, identifying clear roles and timelines for all stakeholders. The GPIRM also summarizes information about innovative new products being developed and sets out the immediate research and development priorities.
The Public Health Team is in the process of updating and re-issuing the publication “Prevention and management of inspective resistance in vectors and pests of public health importance”. The aim of the manual is to provide the principles of effective insecticide resistance management to decision makers and operators in the field in a pragmatic rather than a purely scientific manner. The new edition should be available for distribution early next year.
The use of IRAC Group 4 nicotinic acetylcholine receptor agonists (nAChR) has grown considerably since the introduction of the neonicotinoid insecticide imidacloprid, which was commercialized in 1991. The ten insecticides are classified in four sub-groups 4A-4D. The updated guidelines include a table showing the latest resistance status to the neonicotinoid insecticides….
The CropLife Insecticide Resistance Management Review Group have publish the latest version of their Insecticide Resistance Management Strategies on the CropLife Australia website….
IRAC resistance monitoring methods have now been developed for adult Pollen Beetles (Meligethes aeneus) using different chemistries. There is now Method 011 for pyrethroids, Method 021 for neonicotinoids, Method 025 for organophosphates and Method 027 which is under review for indoxacarb….
IRAC Test Methods for Myzus persicae nymphs (No. 023) and for Aphis gossypii nymphs (No. 024), both for use with the MoA Group 28 active, cyantraniliprole, have been developed and posted on the website by the IRAC Methods Team. The methods are available for downloaded from the IRAC website via the links: Method No. 023 and Method No. 024….
