What are the insects that eat Ailanthus?
Several species of Lepidoptera use the leaves of Ailanthus as food, including the Indian moon moth ( Actias selene) and the common grass yellow ( Eurema hecabe ). In North America the tree is the host plant for the ailanthus webworm ( Atteva aurea ), though this ermine moth is native to Central and South America and originally used other members of the mostly tropical Simaroubaceae as its hosts. In the US, it has been found to host the brown marmorated stink bug, the Asiatic shot-hole borer, and the spotted lanternfly. In its native range A. altissima is associated with at least 32 species of arthropods and 13 species of fungi.

What is the mite that attacks ailanthus leaves?
In North America, the leaves of ailanthus are sometimes attacked by Aculops ailanthii, a mite in the family Eriophyidae. Leaves infested by the mite begin to curl and become glossy, reducing their ability to function. Therefore, this species has been proposed as a possible biocontrol for ailanthus in the Americas. Research from September 2020 indicates a verticillium wilt, caused by Verticillium nonalfalfae, may function as a biological control for A. altissima, with the weevil Eucryptorrhynchus brandti serving as a vector.
What is the Ailanthus tree?
Ailanthus has been used to re-vegetate areas where acid mine drainage has occurred and it has been shown to tolerate pH levels as low as 4.1 (approximately that of tomato juice). It can withstand very low phosphorus levels and high salinity levels. The drought-tolerance of the tree is strong due to its ability to effectively store water in its root system. It is frequently found in areas where few trees can survive. The roots are also aggressive enough to cause damage to subterranean sewers and pipes. Along highways, it often forms dense thickets in which few other tree species are present, largely due to the toxins it produces to prevent competition. The roots are poisonous to people.
What is the chemical in Ailanthus?
Ailanthus produces an allelopathic chemical called ailanthone, which inhibits the growth of other plants. The inhibitors are strongest in the bark and roots, but are also present in the leaves, wood and seeds of the plant. One study showed that a crude extract of the root bark inhibited 50% of a sample of garden cress ( Lepidium sativum) seeds from germinating. The same study tested the extract as an herbicide on garden cress, redroot pigweed ( Amaranthus retroflexus ), velvetleaf ( Abutilon theophrasti ), yellow bristlegrass ( Setaria pumila ), barnyard grass ( Echinochloa crusgalli ), pea ( Pisum sativum cv. Sugar Snap) and maize ( Zea mays cv. Silver Queen). It proved able to kill nearly 100% of seedlings with the exception of velvetleaf, which showed some resistance. Another experiment showed a water extract of the chemical was either lethal or highly damaging to 11 North American hardwoods and 34 conifers, with the white ash ( Fraxinus americana) being the only plant not adversely affected. The chemical does not, however, affect the tree of heaven's own seedlings, indicating that A. altissima has a defence mechanism to prevent autotoxicity. Resistance in various plant species has been shown to increase with exposure. Populations without prior exposure to the chemicals are most susceptible to them. Seeds produced from exposed plants have also been shown to be more resistant than their unexposed counterparts.
How many petals does an Altissima have?
The individual flowers are yellowish green to reddish in color, each with five petals and sepals. The sepals are cup-shaped, lobed and united while the petals are valvate (i.e. they meet at the edges without overlapping), white and hairy towards the inside. They appear from mid-April in the south of its range to July in the north. A. altissima is dioecious, with male and female flowers being borne on different individuals. Male trees produce three to four times as many flowers as the females, making the male flowers more conspicuous. Furthermore, the male plants emit a foul-smelling odor while flowering to attract pollinating insects. Female flowers contain 10 (or rarely five through abortion) sterile stamens (stamenoids) with heart-shaped anthers. The pistil is made up of five free carpels (i.e. they are not fused), each containing a single ovule. Their styles are united and slender with star-shaped stigmata. The male flowers are similar in appearance, but they lack a pistil] and the stamens do function, each being topped with a globular anther and a glandular green disc. The fruits grow in clusters;similar to the Ash ( Fraxinus excelsior), the fruits ripen to a bright reddish-brown color in September. A fruit cluster may contain hundreds of seeds. The seeds borne on the female trees are 5 mm in diameter and each is encapsulated in a samara that is 2.5 cm (0.98 in) long and 1 cm (0.39 in) broad, appearing July though August, but can persist on the tree until the next spring. The samara is large and twisted at the tips, making it spin as it falls, assisting wind dispersal, and aiding buoyancy for long-distance dispersal through hydrochory. Primary wind dispersal and secondary water dispersal are usually positively correlated in A. altissima, since most morphological characteristics of samaras affect both dispersal modes in the same way – except for the width of the samaras, which in contrast affects both types of dispersal in opposing ways, allowing differentiation in the dispersal strategies of this tree. The females can produce huge numbers of seeds, normally around 30,000/kg (14,000/ lb) of tree, and fecundity can be estimated nondestructively through measurements of diameter at chest height.
Where is Ailanthus found?
Ailanthus has also been introduced to Argentina, Australia (where it is a declared weed in New South Wales and Victoria), New Zealand (where it is listed under the National Pest Plant Accord and is classed an "unwanted organism"), the Middle East and in some countries in South Asia such as Pakistan.
How to control ailanthus?
By coordinating spraying or other control methods with harvesting and other forest management operations , the wood can be utilized and invasive species impact to the forest can be reduced. Basal spraying the Ailanthus a few weeks before harvest will minimize risk of stump and root sprouts while still leaving the wood usable. Even if the trees are not harvested, it is important to control them to reduce the impact from sprouts and seeds regenerating in the forest. Invasive species control should be part of all forest management plans. Working with Virginia Tech and several local woodworkers, research and evaluation on potential uses of Ailanthus was conducted. Ailanthus trees from several sites were harvested and processed into various products to determine mechanical and physical properties and what might be feasible for commercial use. Based on stated uses in its native habitat of China, products evaluated were pulpwood, firewood, charcoal, lumber, pallet stock and secondary wood products. Some of the results are compared with local native species to help with evaluation. Ailanthus characteristics can be quite variable depending on its location and growth patterns. Research has shown differences in mechanical and physical properties in different parts of the country. It is a ring-porous tree and produces lumber that looks very similar to ash. Faster growing trees that are more open-grown tend to have more stresses in the wood, which lead to higher rates of warping, twisting, cupping, and less stability and strength compared to slower, straighter- growing trees. Ailanthus has very soft, corky pith that can lead to utilization problems for most products. It is recommended that all sawed products not include any pith wood to minimize potential impacts to strength and stability. Ailanthus tends to have a high moisture content when green that impacts its strength and susceptibility to mold and stain. It is known to have a strong odor when leaves and branches are crushed or broken. Although there appeared to be a mild odor from green materials, especially if they contained bark, there is no apparent odor in finished products.
What herbicide is used to kill ailanthus?
Another herbicide, which has been shown to be effective for basal bark control of Ailanthus, is imazapyr.

Thorough wetting is necessary for good control.
