This 2 mm small beetle belongs to the bark beet<\/wbr>les (Curculionidae)<\/em>. The beetle is dark brown to black and digs tunnels in conifers, preferably in Nor<\/wbr>way spruce and the Larch Tree (Larix deciduas)<\/em>. This beetle is found throughout Europe.
\nThe Six toothed bark beetle primarily affects the tops of trees; unlike the European spruce bark beetle (Ips typographus)<\/em> and the Larch <\/wbr>bark beetle (Ips cembrae)<\/em>, which affect the entire tree.
\nSix toothed bark beet<\/wbr>les swarm around the tops of Norway spruce<\/a> trees. Females bore tunnels in the branches and lay eggs in recesses adjacent to the main corridor, creating a star-shaped pattern.
\nAdult Six toothed bark beet<\/wbr>les hibernate in the ground; eggs are moderately hardy, allowing them to hibernate as well.
\nInfestation by the Six toothed bark beetle is often noticed too late. There is no sawdustlike boring dust (frass), as is common in other bark beet<\/wbr>les. It is only when the trees yellow and lose needles that the presence of the beet<\/wbr>les is noticed. Especially during dry summers and young plantings of conifers dry out quickly, the Six toothed bark beetle can become a major pest and destroy plantings in a short period of time.
\nSix toothed bark beet<\/wbr>les often appears when the tree is already infested by other insects.[\/vc_column_text][\/vc_column][\/vc_row][vc_row equal_height=”yes”][vc_column width=”1\/3″][vc_custom_heading text=”Where to find” font_container=”tag:h4|text_align:center|color:%23ffffff” google_fonts=”font_family:Lato%3A100%2C100italic%2C300%2C300italic%2Cregular%2Citalic%2C700%2C700italic%2C900%2C900italic|font_style:400%20regular%3A400%3Anormal” css=”.vc_custom_1537946500082{background-color: #536895 !important;}”][vc_column_text el_id=”entrytxt” el_class=”entrytxt” css=”.vc_custom_1687775683602{padding-left: 15px !important;}”]<\/p>\n
