Longhorn beetles (Cerambycidae) as a potential pest insect on plantations of shrubby willow?

摘要

The paper presents the results of cyclic catches of the longhorn beetles carried out on the eight year old willow plantation located near the city of Olsztyn. The main identified species were: European musk beetle (Aromia moschata L.), large poplar longhorn (Saperda carcharias L.) and longhorn beetle (Oberea oculata L.) from the family Cerambycidae. It was found that adults of the longhorn beetles preferred feeding on willow plants grown for the wicker industry purposes as well as on the south edge of plantations. Larvae of longhorn beetles damaged rootstocks causings drilled channels. The level of damage to rootstocks of clones of Salix spp. depended on the content of salicine. Due to harmfulness of the longhorn beetles, they should be considered as serious potential pests of willow plantations in the district of Olsztyn.
