IRAC held their 48th International Spring Meeting at Syngenta’s Research Centre in the UK on 18-22 March 2013. There were 12 session held over the 5 days including various working group planning meetings, a meeting of the IRAC Executive, and an “International Day’ with a session of guest speakers covering different aspects of resistance and
The IRAC Lepidoptera WG has just updated the popular Diamondback Moth (Plutella xylostella) poster that outlines the basic biology, resistance mechanisms and management along with general IRM strategies and modes of action available to control this pest. See the poster.
A new guideline has been published by IRAG UK which provides advice on the control of grain aphid (Sitobion avenae) populations that may contain individuals with kdr resistance to pyrethroid insecticides commonly used for aphid control on UK cereals. The guideline can be downloaded from the website www.pesticides.gov.uk or via this link.
IRAC, in consultation with its Executive member companies and representatives, have developed a general one-page position statement that presents the IRAC view on the use of mixtures and their relevance to insecticide resistance management. This includes the crop and public health sectors but more specific guidance, relevant to each area, will be developed over time
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
