THE WORLD HAS DECLARED WAR
ON THE EMERALD ASH BORER BEETLE
WORLD WAR B
WHAT IS THE EMERALD ASH BORER BEETLE
ITS A KILLER OF ASH TREES.
These insects normally serve to kill weakened trees,a part of the natural nutrient recycling scheme.
However, emerald ash borers kill vigorously growing or weakened ash trees.
What do emerald ash borers look like
Adult beetles are bright metallic green in color with a very short antennae.
Adults are about one half inch long and one-eighth inch wide.
The Larvae are creamy white in color and have flattened segmented bodies
Older larvae grow up to an inch long.
Where did the emerald ash borer come from
The natural range of this beetle is northern China, Korea, Japan, Mongolia and eastern Russia.
How did emerald ash borer get to the United States
How else, it was imported.
What types of trees does the emerald ash borer attack
In North America, it is only found in ash trees
Ash trees in any setting (forest, landscape, woodlots, or fencerows) have been affected in infested areas.
Branches as small as 1 inch diameter to trunks exceeding 2 feet in diameter have been colonized by this beetle.
What happens to infested ash trees
Tunnels excavated by feeding larvae destroy the water and nutrient conducting tissues under the bark; this effectively starves the ash tree. The canopy of heavily infested trees will begin to die, usually near the top and progressing downward. Sometimes, infested ash trees produce epicormic (“water”) sprouts on the trunk or branches below emerald ash borer activity. Adult feeding (removal of tissue along leaflet edges) can be seen on affected ash trees. The bark may crack directly over larval galleries. Adult beetles chew characteristic “D”-shaped exit holes as they leave former feeding sites below the bark. Woodpeckers often are found on infested ash tree trunks, feeding on larvae; this is most often noted during winter. Trees attacked by the emerald ash borer die within 1-3 years.
How does the emerald ash borer spread to new areas
On its own, the beetle moves slowly through the landscape, approximately one mile annually. However, humans can greatly accelerate the spread of this exotic insect by moving infested nursery stock, firewood and logs to un-infested areas. Emerald ash borer movement into parts of Michigan outside of the Detroit area, Ohio, and Indiana has been the direct result of moving these ash products.
What is the life cycle of the emerald ash borer
Adults are present from mid-May through late July, and feed on ash leaflets.
Following mating, female beetles lay eggs (average 60 – 90 per female) in bark cracks.
Tiny white larvae hatch from eggs within one week and then bore through the bark and into the cambium.
Larvae feed under ash tree bark from mid-summer through the next spring, producing “S”-shaped tunnels.
Pupation occurs in spring and the new generation of adults emerges shortly thereafter.
It is generally considered that the emerald ash borer completes a generation in one year.
However, reports of a generation requiring two years to complete development have been made when the host tree was vigorous and apparently healthy.
Is there any known natural resistance in ash trees to the emerald ash borer beetle.
Trees have 2 know defense systems and must be healthy to utilize them.
Ash tree’s that are healthy with a high brix content and vigor are better able to fight off the invasion.
How can I protect my ash tree
Keep your Ash tree healthy.
Minimizing known stressors should be practiced for ash, as well as other tree species.
Providing water during very dry periods (water applied evenly over the soil/lawn under the tree canopy twice a month) is encouraged.
