Results from the 2011 monitoring can be seen in the new poster from the IRAC Coleoptera WG. The survey show that pyrethroid resistant populations of pollen beetle were the dominant population type in all the countries surveyed, except Romania, Ukraine and Hungary and that pyrethroid resistant populations are generally increasing in frequency across Europe. Most
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.
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.
A new fruit fly species, morphologically very similar to B. dorsalis, has been reported spreading rapidly in central Africa. This new pest is attacking mangoes, citrus and other tropical fruits. It was recently described and called Bactrocera invadens (Drew et al., 2005). Its finding in Sri Lanka confirmed its suspected Asian origin. Monitoring is ongoing in S. Africa of this
A total of 93 Myzus persicae populations from stone fruit orchards and other crops in S. Europe were sampled and analysed to determine the resistance status. The results confirm the presence of neonicotinoid-resistant aphids in many of the stone fruit orchards of southern France and North East Spain as well in the Emilia-Romagna region of Italy. The surveys
The latest issue of the IRAC MoA Classification has now been released and posted on the MoA Team page of the website (MoA Classification Scheme v7.2). Changes include the addition of some new actives and the re-classification of a couple of existing actives. A third edition of the small IRAC MoA booklet has been printed
A great new booklet from IRAC giving some background on the biology of Tuta absoluta and outlining IRM guidelines to help manage this pest.
A great new IRM Operational Vector Manual has just been published by IRAC providing the reader with practical knowledge and tools required to implement insecticide resistance management in vector control programmes. This pocket size booklet is a shortened version of the earlier larger IRAC Vector Manual. Both the full version and smaller operational pocket version
In this latest issue (No. 27) there is a report on the 46th IRAC International Meeting and updates on new resources and publications from the IRAC MoA, Public Health and Methods Teams. We also spotlight some of the recent resistance articles that have appeared in journals over the last few months along with the usual
IRAC International held their 46th meeting in the CropLife International offices in Brussels on 28th – 31st March 2011. This was our biggest ever meeting with 46 participants, including visitors from the European resistance action groups as well as IRAC representatives from around the world. The meeting consisted of a mixture of concurrent IRAC working
