Overview

Randomized trial evaluates tree injection effectiveness against I. typographus in Norway spruce, suggesting a promising pest control method.

Key Points

  • This research aims to evaluate the effectiveness of tree injection of emamectin benzoate for controlling Ips typographus in Norway spruce.
  • Efficacy assessed in 2022 and 2023 at 10 sites with five injected and five control trees per site.
  • Each tree received 4 mL of a 4.5% emamectin benzoate solution per hole, and all trees were baited with a pheromone lure.
  • Trees were debarked at seven sections to record the number and lengths of maternal and larval galleries.
  • The number of larval galleries was significantly lower in treated trees compared to controls.
  • Maternal and larval galleries in injected trees were significantly shorter than in control trees.
  • Galleries decreased in length toward the top of the tree starting from the third section.
