The relationship between Nemozoma elongatum (Coleoptera: Trogossitidae) and its primary bark-beetle prey-species

Key message

Nemozoma elongatum (Linnaeus, 1761) shows a positive response to artificially produced lures targeting its two main prey species, Pityogenes chalcographus (Linnaeus, 1761) and Taphrorychus bicolor (Herbst, 1793), with a preference for P. chalcographus. We do not recommend using these lures in traps because they could unintentionally capture N. elongatum. However, these lures could potentially aid in controlling target pests by leveraging allochthonous kairomones to attract predators to areas with higher pest densities.
