In 2010 the IRAC Oilseed Rape Working Group in collaboration with multiple researchers located around Europe, continued to monitor the susceptibility status of pollen beetle samples to pyrethroid insecticides. A summary of the findings from this survey can be found on our 2010 pollen beetle monitoring poster. In order to help monitor potential susceptibility changes…
Aphid monitoring surveys in peach orchards conducted by Syngenta Crop Protection and Bayer CropScience have revealed that some populations of the green peach aphid (Myzus persicae) in Southern France and Northern Spain have developed high levels of resistance to neonicotinoid insecticides. For further details and recommendations on resistance management in the affected areas please refer…
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…
Two new posters from the IRAC Public Health Team and a further poster from the IRAC MoA Team all relate to different aspects of resistance management in mosquitoes as vectors of malaria. Topics covered by the posters include a general overview of the importance of insect resistance management, the increasing importance of biomolecular techniques for…
IRAC has just published the second edition of the very popular manual “Prevention and Management of Insecticide Resistance in Vectors of Public Health Importance”. This has been extensively revised and updated with many completely new sections added to chapters, along with further graphs and figures including some very useful flowcharts explaining resistance management best practice…
The latest issue of the IRAC MoA Classification has now been released and posted on MoA Team page of the website (MoA Classification Scheme v7.0). Changes include the addition and classification of some further actives as well as more information in the appendix regarding the group descriptors, the procedure for updating the scheme and a…
This major international conference, the sixth in an ongoing series, will review new research on the origins, nature, development and prevention of resistance to insecticides, fungicides and herbicides. It will provide a forum for researchers, consultants, regulators and industrialists to present and discuss approaches to overcoming this continuing and important constraint to effective crop protection.…
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…
IRAC International has just designed and printed a new pocket-sized guide to MOA classification. It includes an introduction to the importance of MOA for resistance management, a list of MOA groups in numerical order with corresponding active ingredients, pest specific lists of MOA by target site and an alphabetical list of active ingredients along with their MOA…
The popular poster showing MOA classification by group and chemical structure has now been translated into Spanish, Chinese and Portuguese. Further translations are planed in the future. To view or download the files click on the appropriate link: English, Spanish, Portuguese, Chinese. Full information on the scheme can be found in the IRAC MOA Classification document.
