Behaviour of European spruce bark beetle - Ips typographus (L.) on poisoned traps

Deployment of poisoned trap trees/logs is efficient suppressive method to fight Ips typographus (L., 1758) (Coleoptera: Curculionidae: Scolytinae), a calamity pest of spruce stands in the European area during the gradation period. Logs from Picea abies (L.) H. Karst., 1881 (Pinales: Pinaceae) laid as traps were baited IT Ecolure pheromone and were treated with Forester insecticide containing cypermethrin as the active substance. Catching frames were placed under the pheromone trap to gather dead imagoes. Behaviour of imagoes was observed directly in the field and recorded by camera; video records were evaluated in the laboratory.
Higher mean of air temperature affected favourably the flight activity of Ips typographus, increased the frequency of arrival on and departure from the surface of poisoned trap tree; the imagoes stayed on the trap tree for shorter time. The numbers of dead imagoes under the trap trees did not depend on the temperature.

The dataset consists of a tabular data file named: ips_pt_dryad_data_2025_01_21.xlsx

Poisoned trap trees/logs baited with pheromone and treated with cypermethrin effectively suppressed *Ips typographus* during outbreaks in spruce stands. Higher temperatures increased beetle flight activity and reduced their time on traps. Mortality ranged from 18–21%, with an additional 40–60% dying later from contamination. No boring behavior was observed.
