Summary: In the city of Krasnoyarsk the study of mass reproduction of insects was carried out at the end of the 20th century, so there is a need for a modern assessment of complexes of dendrophile insects. The purpose of our research was to identify a complex of internal phyllophagous insects of poplar plantations on the territory of Krasnoyarsk and to assess the damage of poplar leaves by them. Collecting insects and their censuring were carried out in seven trial areas in the territory of Krasnoyarsk during the summer of 2016. Intact and damaged leaves were counted on the terminal ends of the branches 50 cm long. In total, 3620 leaves were analyzed. The complex of cryptozoic species of insects – leaf miners, gall-formers, leaf rollers – was identified. The species diversity of the entomocomplex is low. The damage of leaves by gall-formers and leaf rollers in the city is on average 2.5 and 1.1 %, respectively, by leaf miners – up to 10 %. Statistically significant differences were found in the proportion of intact leaves in different parts of the city. © Petrozavodsk State University |
