Effective IRM strategies: Sequences or alternations of MoA Effective insecticide resistance management (IRM) strategies seek to minimise the selection of resistance to any one type of insecticide. In practice, alternations, sequences or rotations of compounds from different MoA groups provide sustainable and effective IRM. Applications are often arranged into MoA spray windows or blocks that are defined by the stage of crop development and the biology of the lepidopteran species of concern. Local expert advice should always be followed…
The Sucking Pest WG was formed in 2008 to develop and disseminate IRM strategies for major sucking pests of global importance. It is recognised that this is a broad remit given the range of crops and pests, but by focusing on specific areas, the team is convinced that it can deliver strategies for key pests such as whiteflies, aphids and thrips, before moving on to consider other groups. The Sucking Pest WG absorbed the earlier Neonicotinoid WG in 2009…

(Download the information as a pdf file) Overview of Insect Resistance Monitoring for Insecticides: Factors Impacting the Design and Implementation of Resistance Monitoring Program Background The development of insecticide (and acaricide) resistance in insect/mite pests is an evolutionary process in response to the selection pressure imposed by use of insecticides to manage pest populations. The first insect resistance case was documented in the US to an inorganic insecticide (sulfur-lime) as early as in 1914. Currently, for almost every class…
The availability of standard, validated and easy-to-run methods for resistance detection in the world’s major insect pests is crucial for successful monitoring of resistance problems. The IRAC Methods Team has worked to develop, validate and collate approved methods and make these available via the IRAC website and the online tool, eMethods. The work of the Methods Team involves interaction with other IRAC Teams and Working Groups as well as cooperation with external experts in academia and institutes. The Methods…
