Lynne Matthews is taking over from Fabrice Robin as BASF representative on the Pollen Beetle WG. Lynne has responsibility for insecticides in the BASF UK based technical team and has been organising the PB monitoring there in the last few years….
At the recent first conference call of the new IRAC Lepidoptera WG it was agreed that the first priority was to investigate the resistance of the tomato leafminer Tuta absoluta and the diamond back moth Plutella xylostella. Initial actions identified were to develop educational posters on both these pests outlining the resistance status, mechanisms and chemistry involved. The objective is to have the posters completed by the time of the IRAC Spring Meeting in April….
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….
The IRAC Sucking Pest Working Group has just published an updated version of their poster titled “Major mechanisms of insecticide resistance in green peach aphid Myzus persicae Sulzer“. The sections on the poster include, enhanced expression of esterases, MACE (modified acetylcholinesterase), nAChR target-site resistance, kdr (knock-down resistance) and resistance management guidelines….
The use of IRAC Group 4 nicotinic acetylcholine receptor agonists (nAChR) has grown considerably since the introduction of the neonicotinoid insecticide imidacloprid, which was commercialized in 1991. The ten insecticides are classified in four sub-groups 4A-4D. The updated guidelines include a table showing the latest resistance status to the neonicotinoid insecticides….
The CropLife Insecticide Resistance Management Review Group have publish the latest version of their Insecticide Resistance Management Strategies on the CropLife Australia website….
The English version of the IRAC Insecticide Resistance Management Video has proved so popular that we have now translated the video into 6 other languages. These are Chinese Mandarin, Japanese and Latin American Spanish and Portuguese, French and Hindi….
In a situation in which running real-world experiments is impractical (or even impossible), computer simulations offer a powerful solution to understand complex problems. This is exactly the case of resistance-evolution prediction: Although fast from an evolutionary perspective, the time and spatial scales involved in this process are simply too large to be dealt with experimentally. The underlying evolutionary processes of resistance development are relatively well known, however. With this knowledge, researchers can build mathematical models to describe and mimic the…
The 2019 IRAC International Spring meeting was held at the Double Tree Suites by Hilton at Disney Springs, Orlando, March 26-28th. There were 12 sessions organised over the 3-days which were well attended by the 27 meeting participants. Day-1 was spent reviewing the work of the various international working groups and country teams during the previous year with Day 2 & 3 spent planning the work for the following year. The meeting finished with an IRAC Executive session where there…
