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.
