Agrilus anxius, the bronze birch borer, is a wood-boring buprestid beetle native to North America, more numerous in the warmer parts of the continent and rare in the north. [1] It is a serious pest on birch trees (Betula), frequently killing them. The river birch Betula nigra is the most resistant species, while other American birches are less so.
Bark beetles enter trees by boring holes in the bark of the tree, sometimes using the lenticels, or the pores plants use for gas exchange, to pass through the bark of the tree. [3] As the larvae consume the inner tissues of the tree, they often consume enough of the phloem to girdle the tree, cutting off the spread of water and nutrients.
Beech bark disease is a disease that causes mortality and defects in beech trees in the eastern United States, Canada and Europe. [1] [2] [3] In North America, the disease occurs after extensive bark invasion by Xylococculus betulae and the beech scale insect, Cryptococcus fagisuga. [4]
Co-existing tree and plant species will gain in the void left by the affected species, but often providing different functions. Eastern hemlock, for example, is commonly replaced by black birch in the northeast—a slow-growing, shade-tolerant and deep shade producing evergreen tree, replaced by a fast-growing, open, deciduous tree. While short ...
The goldspotted oak borer is just 14 miles from the Santa Monica Mountains' 600,000 oak trees and threatens to devastate forests throughout California, harming wildlife and increasing fire risks.
The bark beetle is an insect of the subfamily Scolytinae, containing around 6000 species, which live and reproduce in the inner bark of trees.Upon successfully entering a tree, they mate and the female starts to burrow a labyrinth of tunnels running along the inner bark called egg galleries where she then lays her eggs.
The Asian longhorned beetle is a wood-boring insect that attacks 12 types of hardwood trees in North America, including maples, elms, buckeyes, birches and willows. Infested trees do not recover ...
