…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 insecticides in South-East Sicily. The potential integrated control strategies are discussed, aiming to prevent further directional selection of resistance alleles via the adoption of stringent IPM strategies inclusive of reasoned IRM/MoA alternation programmes.

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 be used for susceptibility baseline testing and resistance monitoring….
