English title: The Finnish nomenclature of insects.
English keywords: nomenclature; forest insects

The need for standard Finnish names for the harmful or beneficial insects in agriculture rose in the 1930s, and a committee was formed in 1932 to work out nomenclature for the insect species. In 1933, a similar committee was formed to compile a nomenclature for forest insects. The old popular names, if such names existed, were used primarily. Some of the insects had been named also in the earlier literature, even if all the names had not been taken in common use. Some names were translated from the scientific names. Emphasis was given to the habits or habitats of the insect. An attempt was made to shorten the former names if needed.

English title: Bark beetles and insect damages in Finnish forest.

The aim of the study was to investigate the abundance of bark beetle species and their damage in Finland. The bark beetle populations were studied in several areas in Finland, both in sites with known beetle damage and without. Two-meter wide lines were measured in the sample plots, where all trees were studied for bark beetle damage in the stem and the crown of the trees. The abundance of bark beetle species and the beetle damages in 25 study areas, and 52 different species are discussed in detail.

Divided by their lifestyle, the most important groups of bark beetles are the pine shoot beetles (Tomicus sp.), beetles reproducing in Scots pine (Pinus sylvestris L.) stems and branches under the bark, beetles reproducing in Norway spruce (Picea abies (L.) H. Karst.) stems and branches under the bark, beetles living in the other coniferous trees, beetles reproducing in roots, beetles reproducing under the Betula sp. bark, beetles reproducing in other deciduous trees and beetles reproducing inside of the stems. Of individual species, Blastophagus piniperda (now Tomicus piniperda) and B. minor cause worst damage to pine and Ips typographus (L.) and Pityogenes chalcographus (L.) to spruce. Serious damage is caused also by Xyloterus lineatus to coniferous trees, Polygraphus polygraphus and P. subopacus to Norway spruce and Scolytus Ratzburgi to Betula sp.
