Tree-of-Heaven is an invasive species, but now researchers may have found a way to control it.
Researchers at USDA report finding a potential natural enemy for Tree-of-Heaven in France.
It’s a mite that may be a solution for managing infestations of the tree in both Europe and the U.S. Scientists say the mites are microscopic in size and form dense populations, mainly under younger leaves of the plant. The mites cause the leaves to curl up and down and then turn yellow. Once the mites take over, plant growth is reduced.
Native to China, the Tree-of-Heaven was introduced in the U.S. and Europe in the 1700s. Despite its angelic name, the tree is invasive due to its ability to crowd out native species. The plant can cause damage to pavement, sewers, and buildings.
It has also helped advance the spread of the spotted lanternfly, which feeds on fruit-bearing trees.
Scientists are hoping natural enemies like the mites will one day be more environmentally-friendly and cost-effective to mechanical weed control and herbicides.
