The Michigan departments of Natural Resources and Agriculture and Rural Development today announced the addition of beech leaf disease to the state's invasive species watch list. Invasive species on the watch list have been identified as posing an immediate or potential threat to Michigan's economy, environment or human health. These species either have never been confirmed in the wild in Michigan or have a limited known distribution. Beech leaf disease is associated with the microscopic worm Litylenchus crenatae, a nematode that enters and spends the winter in leaf buds, causing damage to leaf tissue on American beech and European and Asian beech species. Infestations result in darkened, thick tissue bands between leaf veins, creating a striped effect on the leaves, leaf distortion and bud mortality. Trees weakened by leaf damage become susceptible to other diseases and can die within six years. Beech leaf disease has not been found in Michigan. The disease was first discovered in Ohio in 2012. Since then, it has been identified in seven eastern states and Ontario.

In May 2010 the last boll weevil was trapped in the state and in March 2012 the boll weevil was declared eradicated from the state of Louisiana. The Eradication Program is now at a maintenance level, funded through grower maintenance inspection fees. Traps are placed and monitored according to an approved trapping protocol. Cotton producers have seen increases in yields along with a reduction in the cost of insect control.

The emerald ash borer, a severe insect pest of ash trees, was confirmed in Webster Parish in February 2015, making Louisiana the 25th state to confirm the presence of this beetle. In 2014, the LDAF started a "Don’t Move Firewood" campaign which is geared toward educating people about the risks of transporting pests to other locations where some can do harm. It is best to purchase firewood not more than 10 miles from where it will be burned.

The emerald ash borer is a metallic green beetle that bores into ash trees feeding on tissues beneath the bark, ultimately killing the tree. It is not native to the United States and was first found in the U.S. near Detroit, Michigan in 2002. In 2013, the emerald ash borer was found in Granville, Person, Vance, and Warren counties in North Carolina. In 2015 it was found in many additional counties, and a statewide EAB quarantine went into effect in North Carolina.
