Forest Pests

STARKVILLE, Miss. -- Mississippi is one of just two states east of the Mississippi River not infested with emerald ash borers, and landscapes need everyone’s help to keep it that way.

Blake Layton, Mississippi State University Extension Service entomologist, said the emerald ash borer -- or EAB -- is an invasive, nonnative pest that has killed hundreds of millions of ash trees in the eastern U.S. Fairly expensive, annual treatments can protect high-value landscape trees, but they have to be applied preventatively.

RAYMOND, Miss. -- Despite a slow housing market and other lingering effects of the recession, Mississippi’s forests remain the state’s second most valuable agricultural commodity for 2017.

John Auel, an assistant Extension professor of forestry at Mississippi State University, estimates the value of forest products is $1.4 billion, which is a decrease of 8.6 percent from 2016. However, 2017 numbers are almost 40 percent higher than they were in 2009, when the industry experienced its lowest valued harvest of the 2007-2009 recession.

STARKVILLE, Miss. -- Mississippi is having a breakout of tiny beetles that use pheromones to gather sufficient numbers of reinforcements to overwhelm healthy trees.

Current Mississippi Forestry Commission flyovers indicate nearly 5,000 separate Southern pine bark beetle outbreaks across the state. Outbreaks can range from just a few trees to more than an acre of infested and dying pines.

Outbreaks are especially bad on national forestland, but homeowners and private landowners are also experiencing the problem.

STARKVILLE, Miss. -- It may have taken only one beetle and the fungus it carried to kill one-third of the nation’s redbay trees, according to scientists at Mississippi State University and the University of Florida.

Laurel wilt is a devastating disease of any tree or shrub species in the laurel family. The redbay ambrosia beetle, introduced from Asia into Georgia in 2002, carries the deadly fungus.
