SOME BIOLOGICAL FEATURES OF THE CRUSTACEAN TYPOGRAPHER

The article presents bark-eating typographus (Ips typographus), i.e., the big spruce bark-eater, which is one of the most dangerous pests, living mainly on spruce, in most cases on sochi and pine (А.Д. Маслов-2002), rarely on cedar and larch. It settles with high intensity on large and medium-sized fir trees of cool and moist places, high productivity and low frequency, especially in the edges of the forest, where there is relatively good lighting and warmth, on newly cut, cut-broken and weakened trees for various reasons, on branches, on fir-tree residues left in the forest. , in warehouses and wood processing plants, on unpeeled logs, the trunk and bark of which are still raw. This pest is a representative of the Eurybiont group, it is characterized by a wide ecological range of distribution and great plasticity to the conditions of existence. The damage caused by its negative impact is very great from an ecological and economic point of view, therefore a detailed study of the biological features of the pests included in the crustacean family is necessary and necessary, even for the purpose of properly planning the measures to be taken against them. For example, one of the measures to combat the bark-eating typographer is the effective placement of pheromone-based insect repellents, while the natural enemy Rhizophagus (Dendroctonusmicans) gives good results against the large spruce borer (Phizophagusdisparpayk) under laboratory conditions and its settlement in spruce groves inhabited by the borer.
