Attractiveness of synthetic pheromones for stem pests monitoring in pine stands in Belarus

Dynamics of pine stands dieback in 2016‒2021 in the forest fund of Belarus is presented. The area of clear sanitary cuttings was 112.3 thousand hectares.
The results of field tests on attractiveness assessment of Belarusian synthetic pheromones “IPSVABOL V”, “IPSVABOL SH”, “MONVABOL” using barrier traps for monitoring the abundance of sharp-dentated (Ips acuminatus G yll.) a nd s ixtoothed (Ips sexdentatus Boern.) bark beetles and longhorn beetles (Monochamus spp.) in pine stands are presented. During insect abundance monitoring in pine stands, it was found that the synthetic pheromone “IPSVABOL V”, “IPSVABOL SH” and “MONVABOL” are highly attractive to beetles of the sharp-dentated, six-toothed bark and longhorn beetles of the genus Monochamus when monitoring their abundance in pine stands. It was revealed that the first generation flying of the sharpdentated and six-toothed bark beetles are the most widespread and higher by 1.8‒4.5 and 3.8‒5.1 times of the second generation flying of these stem pests, respectively.
For the first time, scales for assessing the abundance and methods for pheromone monitoring of the sharp-dentated and six-toothed bark beetles, and longhorn beetles (Monochamus spp.) have been developed. The use of the developed scales in forest protection practice makes it possible to quickly control the abundance of these stem pests and their distribution in pine stands for appointment of forest protection measures.
