Abstract 1 The feeding preferences of Hylobius abietis (L.) were studied in a series of choice and no-choice trials for insecticide-treated food, time-to-death studies and arena trials.
2 Treatment of Scots Pine twigs with a pyrethroid insecticide, lambda-cyhalothrin, was compared with twigs treated with imidacloprid, a neonicotinoid.
3 Clear avoidance of insecticide-treated food sources, with strong evidence of selection for untreated food sources, was shown.
4 In addition, it took up to 3 weeks for H. abietis to die from insecticide poisoning when fed on treated food and, during this time, it was potentially capable of finding new untreated food sources.
