Buckthorn Watch: Studying the Invasive Plant Common Buckthorn
MSU Extension Service
Michigan State University
Extension Publications E3146

Common buckthorn is a fast-growing shrub that spreads by roots and seeds, making it an excellent hedge plant. Unfortunately, these characteristics allowed it to become a successful invasive species. This plant has escaped from home landscapes and is now common in forests, old fields, parks and agricultural fence rows across much of the northern United States and Canada. In addition, buckthorn harbors soybean aphids, an invasive pest of soybeans. This publication includes information to identify buckthorn along with a small poster that features the plant’s negative environmental impacts.

Insecticide Options for Protecting Ash Trees from Emerald Ash Borer1

Emerald ash borer (Agrilus planipennis Fairmaire), an invasive insect native to Asia, has killed tens of millions of ash trees in urban, rural and forested settings. This beetle was first discovered in 2002 in southeast Michigan and Windsor, Ontario. As of June 2009, emerald ash borer (EAB) infestations were known to be present in 12 states and two Canadian provinces. Many homeowners, arborists and tree care professionals want to protect valuable ash trees from EAB.

Spotted Wing Drosophilia
MSU Extension Service
Michigan State University
Extension Publications E3140

The Spotted Wing Drosophila (SWD) is a small vinegar fly with the potential to damage many fruit crops. It was first detected in Michigan in late September 2010. Unlike most other vinegar flies that require damaged fruit to attack, SWD causes damage when the female flies cut a slit and lay eggs in healthy fruit. This insect is a pest of most berry crops, cherries, grapes and other tree fruits, with a preference for softer-fleshed fruit.
