The emerald ash borer (Agrilus planipennis), also known by the acronym EAB, is a green buprestid or jewel beetle native to north-eastern Asia that feeds on ash species (Fraxinus spp.). Females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years.
Fraxinus ornus is frequently grown as an ornamental tree in Europe north of its native range for its decorative flowers—the species is also sometimes called "flowering ash". Some cultivated specimens are grafted on rootstocks of Fraxinus excelsior , with an often very conspicuous change in the bark at the graft line to the fissured bark of ...
The emerald ash borer (Agrilus planipennis), also commonly known by the acronym EAB, is a green beetle native to Asia; its larvae kill ash trees. [1] In North America, the EAB is an invasive species, highly destructive to ash trees in its introduced range. The damage of this insect rivals that of chestnut blight and Dutch elm disease. [17]
Hylesinus aculeatus, the eastern ash bark beetle, is a species of crenulate bark beetle in the family Curculionidae. It is found in North America. [1] [2] [3]
European ash in flower Narrow-leafed ash (Fraxinus angustifolia) shoot with leaves. Fraxinus (/ ˈ f r æ k s ɪ n ə s /), commonly called ash, is a genus of plants in the olive and lilac family, Oleaceae, [4] and comprises 45–65 species of usually medium-to-large trees, most of which are deciduous trees, although some subtropical species are evergreen trees.
Corneyanus bark beetles live in the bark of weak or dying trees, researchers said. A photo shows the bark “gallery” where the new species lives. The bark of a Cupressus corneyana tree where ...
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.
Buprestidae is a family of beetles known as jewel beetles or metallic wood-boring beetles because of their glossy iridescent colors. Larvae of this family are known as flatheaded borers. The family is among the largest of the beetles, with some 15,500 species known in 775 genera. In addition, almost 100 fossil species have been described. [1]
