<p>This study was carried on in a Siberian stone pine (Pinus sibirica Du Tour) clone archive located in the south of the Tomsk Region. Fourteen species of phytophagous insect pests were found in this clonal archive.<br />Pineus cembrae is the most frequent insect in the clone archive colonizing the buds, needles and the bark of the young shoots. Of all<br />polyphagues insects, the scarab beetle Melolontha hippocastani Fab. and summer chafer Rhizotrogus solstitialis L. have the most destructive effect in the clone archive. Their larvae eat the roots of young plants. The larvae of elaters Agrypnus murinus L. and Selatosomus aeneus L. and weevil Otiorhynchus ovatus L. are potentially dangerous<br />for the plant host roots. All found insect species in the clone archive are also widely spread in natural and man-made coniferous forests from the Tomsk Region. Their destructive activity in the clone archive may result in serious consequences. They should be controlled by means of pathological methods.</p>
