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

description: 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. Increasing number of live imagoes
 on poisoned trap trees/logs correlated with increasing proportion of
 caught dead imagoes, decreasing length of live imagoes staying on the trap
 tree, and increasing frequency of arrival to and departure from the trap
 tree. The presence of pheromone lure and insecticide treatment induced
 rectilinear and uninterrupted flight towards and away from the pheromone
 lure. No attempt was observed to gnaw an entrance hole.
  Mortality on the poisoned trap tree ranged from 18 to 21%,
 40–60% of poisoned imagoes died later due to the contamination.

 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. **variable name &gt; description** * N(TL) &gt; number of
