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
The CropLife Insecticide Resistance Management Review Group have publish the latest version of their Insecticide Resistance Management Strategies on the CropLife Australia website.
The IRAC Methods Team have produced another video in their series of test method videos. This video shows how to carry out Method No.030 evaluating the susceptibility of stinkbugs to insecticides from mode of action groups, 1A (carbamates), 1B (organophosphates), 3A (pyerethroids), and 4A (neonicotinoids). The method has been validated for Euschistus heros and can
The MoA Classification has been updated by the IRAC MoA Team and the updates approved by the IRAC Executive. The latest version of the Classification Scheme can be downloaded from the IRAC website. The English version of the IRAC Chemical Structures Poster and the small IRAC MoA Booklet have also been update and can be
The paper reports on the sensitivity monitoring executed by DuPont and collaborators in Italy, Spain, Greece since 2009 in order to detect possible sensitivity shifts of T. absoluta from baseline sensitivity to the diamide insecticide chlorantraniliprole (MoA group 28). The results of the 2014 bioassays revealed the first cases of T. absoluta resistance to diamide
The Insecticide Resistance Management recommendations have been developed by IRAC Brazil & IRAC International and in consultation with leading local experts on Brazilian agriculture and resistance management. The recommendations are based on resistance management principles, whilst also considering the need to provide economical pest control. They are intended to provide the basis for developing an
Urgent research to understand the nature and extent of insecticide resistance in an increasingly damaging pest of peas and beans is underway at Rothamsted Research. The work is in response to reports of failure to control the pea and bean weevil (Sitona lineatus) with pyrethroid sprays, which are a special chemical class of active ingredients
In this issue we focus on mode of action (MoA) and its importance in insecticide resistance management (IRM). We present a review paper on IRM and the IRAC MoA Classification and summarize the changes that have been made to the latest version of the classification scheme.

See the poster. Summary of findings: In the majority of countries surveyed, pyrethroid resistant populations of pollen beetle dominate (> 60% are resistant). From the countries surveyed, it is only in Switzerland that susceptible populations dominate but sample size was considered too small to be representative of the overall country situation. During 2014, only 11%
The cotton aphid (Aphis gossypii) is a highly polyphagous pest, which has a host range which includes many commercially grown agricultural and horticultural plant species. Insecticide Resistance has been recorded in cotton aphids since the mid-1960‘s, when organophosphate, carbamate and cyclodiene organochlorines were utilised to control this aphid in a wide range of crops.
