Despite its broad host range, the spotted lanternfly Lycorma delicatula (White), is known to have a marked preference for Ailanthus altissima.However, whether this polyphagous phloem feeder can complete its life cycle in the absence of A. altissima is unknown. A tree with stout branching and a robust look. [1], From Wikibooks, open books for an open world. In addition to its use as an ornamental plant, the tree of heaven is also used for its wood, medicinal properties, and as a host plant to feed silkworms of the moth Samia cynthia, which produces silk that is stronger and cheaper than mulberry silk, although with inferior gloss and texture. https://www.fs.fed.us/database/feis/plants/tree/ailalt/all.html From these areas, tree-of-heaven has spread and become a common invasive plant in urban, agricultural, and forested areas.

Trees harvested for medicinal purposes are usually felled in the spring or autumn, and the bark is removed and dried in the sun. Phytochemical investigations into the compounds, isolated from A. altissima, with biological activities have focussed on the quassinoids, which are considered to be degraded terpenes. However, taken in large doses, the bark extract is highly toxic. The maximum length is 60 cm and it consists of 12 to 25 leaflets and appears late in spring. The biological activities of the quassinoids and canthin-6-one alkaloids isolated from this plant confirm uses in traditional medicine and interest in this plant continues as a result of these biological activities, which make some of these constituents of potential use as templates for new drugs. advanced search... Login. It is hardy to zone (UK) 7. Distribution: Native to China; widely naturalized worldwide. Cutting a full ring will kill the upper part of the tree and cause root suckers to sprout. and Anoplophora glabripennis (Zhang et al., 1992; Santamour and Riedel, 1993). Quite the same Wikipedia.

In France it is cultivated for its leaves, on which the caterpillar of the silk-spinning Ailanthus Moth ( Bombyx Cynthia ) is fed, yielding a silk more durable and cheaper than Mulberry silk, though inferior to it in fineness and gloss. Leaflets are 3-6 inches long, ovate, with the margin almost entire. Tree of heaven. Regional variation has begun to show throughout its range, with trees in the colder northern regions producing heavier seeds than those in warmer regions.

Those strategies involve both controlling Ailanthus and retaining and systemically treating Ailanthus as “trap trees” for SLF. Although it makes a handsome tree, it has become well known as an invasive plant in many parts of the world. As a result, research continues on efforts to produce plant cell cultures of A. altissima high yielding in the quassinoid ailanthone and in the canthin-6-one alkaloids, since the yield of both these products from the mature plant is very low. When the maximum height of 25 m has been attained, the tree has a spread of circa 15 m. Especially in its early years the growth is strong. Ailanthus altissima is a deciduous Tree growing to 25 m (82ft) by 15 m (49ft) at a fast rate. It has a smooth, grey bark with compound leaves which are alternate, odd-pinnate, with 11-25 lanceolate leaflets.
