Assessing Eucryptorrhynchus brandti as a Potential Carrier for Verticillium albo-atrum from Infected Ailanthus altissima
… mortality of the invasive tree of heaven (TOH), Ailanthus altissima (Mill.) Swingle, was first observed in Pennsylvania in 2002 to be caused by an apparently host-specific strain of Verticillium albo-atrum Reinke & Berthold, a soil-borne, vascular wilt fungus. A limited survey conducted in …

Seasonal trends in separability of leaf reflectance spectra for Ailanthus altissima and four other tree species
… spectral separability of the invasive species Ailanthus altissima, commonly called tree of heaven, and four other native species. Leaves were collected from Ailanthus and four native tree species from May 13 through August 24, 2008, and spectral reflectance factor measurements were gathered for …

Biological control of the invasive Ailanthus altissima (tree-of-heaven) in Virginia using naturally occurring Verticillium wilt fungi
The invasive tree-of-heaven, Ailanthus altissima (Miller) Swingle, is widespread and damaging throughout North America. Verticillium wilt disease is emerging as a potentially exciting biological control option for this difficult to control tree. In Virginia, Verticillium nonalfalfae has been …

Quarantine evaluation of Eucryptorrhynchus brandti (Harold) (Coleoptera: Curculionidae), a potential biological control agent of tree-of-heaven, Ailanthus altissima in Virginia, USA
Ailanthus altissima (Mill.) Swingle is a tree native to Asia that was intentionally introduced into the United States in the late eighteenth century. Ailanthus altissima has become an invasive species that has spread throughout most of North America. Lack of effective management tactics for …

Analysis of intraspecific and interspecific interactions between the invasive exotic tree-of-heaven (Ailanthus altissima (Miller) Swingle) and the native black locust (Robinia pseudoacacia L.)
… of native species. The exotic invasive Ailanthus altissima and the native Robinia pseudoacacia are frequently found in disturbed sites and exhibit similar growth and reproductive characteristics, yet each has distinct functional roles such as allelopathy and nitrogen fixation, …

Management of Spotted Lanternfly (Lycorma delicatula) Overwintering Egg Masses and Multiple State Records of Aculops ailanthi, the Potential Biological Control Agent of Tree-of-Heaven (Ailanthus altissima)
… ailanthi, an exotic mite on tree-of-heaven, Ailanthus altissima, from Montgomery County, Virginia, and Wayne County, Michigan, USA. Samples from both states were sent to USDA-ARS for identification, and scanning electron microscopy confirmed the species as A. ailanthi based on the …

Biotic Interaction of Invasive, Early-Succession Trees and Their Effects on Community Diversity: a Multi-Scale Study Using the Exotic Invasive Ailanthus altissima and the Native Robinia pseudoacacia in the Mid-Appalachian Forest of Eastern United States
… of interaction between a non-indigenous invader Ailanthus altissima and its functionally similar native species Robinia pseudoacacia in the Mid-Appalachian region, from an individual scale to a regional scale. These two subject species are common and coexist in early-successional eastern …

Floristic dynamics of Appalachian pine-oak forests over a prescribed fire chronosequence
… of exotic invasive species, but its effects on Ailanthus altissima were inconclusive. Low overstory mortality and prolific sprouting of ericaceous shrubs suggests that understory vegetation effects from single burns are temporary.

Nematicidal, antimicrobial and acaricidal activity of plant secondary metabolites
… we report for the first time about the use of Ailanthus altissima, Capparis spinosa, Melia azedarach and Armoracia rusticana and their secondary metabolites such as α, β- and α, β, γ, δ- unsaturated aldehydes, isothiocyanates and polyphenols as potential nematicidal against the root knot …

Toward optimized surveillance of adventive Trissolcus japonicus (Ashmead) (Hymenoptera: Scelionidae) based on aspects of its foraging ecology
… (YSC) deployed in the lower and mid-canopy of Ailanthus altissima (Mill.) Swingle trees in Virginia captured statistically equivalent numbers of T. japonicus. Season-long monitoring of T. japonicus and H. halys over two seasons resulted in significant correlations between captures of T. …

Epidemiology and Ecology of Verticillium nonalfalfae: Application and intervention efforts to successfully manage tree-of-heaven and restore invaded sites
Ailanthus altissima, or tree-of-heaven, is a problematic invasive tree species distributed around the world. A. altissima was recently found to be susceptible to a soilborne vascular wilt fungus, Verticillium nonalfalfae, in both the United States and Europe. Research to date on its potential as a …
