Pyrethroid resistance monitoring in European populations of pollen beetle ( <i>Meligethes</i> spp.): a coordinated approach through the Insecticide Resistance Action Committee (IRAC)

Pyrethroid-resistant beetles dominate in Western and Central Europe and are becoming established in the North and East, the main oilseed-rape-growing areas of Europe. The development and spread of pyrethroid-resistant pollen beetles highlights the need for effective management strategies for oilseed rape insect pests.
