Ash borer

[Joshlaugh]

I also agree about the "D" shape holes. Those are telltale signs that the EAB has been there. I think most people forget that there are naturally occurring borers in trees too. I have found circular holes in hickory before and obviously that was infected with a wood boring insect but there is a difference when it is a non-native borer that doesn't have any predators to control their numbers.

I work in a park, in fact, I am an assistant park manager for a large metropolitan park. We allow people to bring firewood into the park but not to cut and collect within it. I have never actually checked on the wood being brought in or what county it was from. How could I? Besides this really only pertains to ash trees. As I talk to the visitors I bring up the EAB and try to educate them.

I recently went to a resource management conference where we talked a lot about EAB. For those really nice ash trees a person can treat the tree prior to infestation to deter the borers. Several kinds of chemicals can be injected or basally sprayed to keep them away. Also the Dept of Ag has released a parasitic wasp from China that is supposed to eat the larvae too.

Some Ohio counties are under quarantine. I can't transport ash material(or even any firewood) from a quarantined county to one that is not but you can travel between counties that are under the quarantine. Also you can't transport between states even if both states have the EAB. Also the State Dept of Ag told us that over 25 million trees have already died because of the borer.

I know the Ash Borer is not native to the US, but I really hate when the solution is to import another non-native insect to kill the first. If I remember right, the flea beetle was imported to eat the leafy spurge up in these parts, but they found that canola was much more attractive, so now my FIL and BIN end up spending big $$$ to kill the beetle that they didn't even have to deal with years ago.

I wonder what that wasp will find as a better prey than the ash borer? It will end up being a beneficial insect....Just you wait and see.

The guys down at the USDA office told me that wood peckers are another tell sign, I guess they go after the larve, He also mentioned that the tops of the tree will usally start to die first and then the rest. Most of the holes I see around here are carpenter ants hiding out in American Elm. I normal will just throw that stuff back in the woods, I had some I took home that I never noticed until they got warm and were on the move.

Agree....I am still waiting to hear about a single non-native spp that was actually a good thing being brought here to the US.

I also have seen where they have a pictorial chart of how to tell the ash tree is dying. The d shape holes, the woodpecker activity, the crown dying, lots of root suckers etc.

Scientists trying Chinese wasps against ash borer
HUNTINGTON, Ind. (AP) -- Purdue University researchers have started releasing wasps imported from China in a test to see whether the insects might help to eradicate tree-killing emerald ash borers.
The beetle is blamed for killing millions of ash trees in Michigan, Ohio, and Indiana since it was first found in the United States in 2002. The insects are so destructive that Fort Wayne officials estimate it could cost $3 million over 15 years to protect its thousands of ash trees.
Scientists hope the wasps will eventually help control the beetle and on Thursday began releasing 200 wasps in a forest at Roush Lake near Huntington, about 25 miles southwest of Fort Wayne.
The wasps being tested lay their eggs into the ash borer's eggs. As the wasps develop, they eventually kill the ash borer eggs. Purdue researchers will test two other wasp species this summer in the same area.
"Our study will determine whether the wasps are able to establish a population, overwinter and effectively control ash borer in the state," said Cliff Sadof, a Purdue entomology professor.
The scientists say the wasps have no stingers and are not aggressive toward humans.
In China, the wasp species reduced ash borer populations by 74 percent in ash trees native to North America, Sadof said.
However, researchers said it could take years for the wasps to become established in Indiana and to reach adequate numbers to significantly curb the ash borer.
Michigan State University has conducted similar research, although no conclusions have been reached. Ohio State University is beginning a study of its own this summer.
The ash borer infestation has Fort Wayne officials looking at ways to protect the city's canopy of nearly 55,000 street trees, about a quarter of which are ash.
Parks superintendent Steve McDaniel said the $3 million estimate was for a plan to remove and replace small ash trees, use pesticide to preserve larger ash trees and let other trees not worth keeping to die if they become infested.
Parks director Al Moll said it would take a sustained effort over several years to keep the trees protected.
"If we don't, we're going to be sitting here three to four years from now asking why we didn't do anything," he said. "To me, I think that's pretty minor (cost), considering what you are protecting."

Interesting, I don't live to far from Huntington, Hope all works out. I just cut a dead Ash tree down today for a buddy, I didn't see any D shaped holes, so who knows.

Here is what my town is doing.

City Takes Proactive Approach toward Emerald Ash Borer Threat

WHEATON, Ill. – The City of Wheaton will begin implementing an ash tree reduction program in response to the threat of an emerald ash borer infestation, which has killed more than 20 million trees in the Midwest. Although the emerald ash borer has not yet been spotted in Wheaton, it has been identified in Carol Stream and Glendale Heights. The highly destructive pest has a history of destroying the vast majority of ash trees in the areas it reaches.

The Public Works Department’s Forestry Division performed an inventory of the nearly 6,500 ash trees on city parkways and classified 764 to be in fair to poor condition. The Forestry Division will be targeting the trees in poor or stressed condition for removal because ailing trees succumb to the emerald ash borer more quickly than healthy trees. Starting this week, crews will begin the process of removing about 200 ash trees. The process is expected to take approximately 12 months, and crews will begin in north Wheaton, which is closest to the location of the emerald ash borer sightings.

Residents whose trees are scheduled for removal will receive a notice in the mail. Homeowners who would like for the Forestry Division to plant a replacement tree where an ash tree was removed may participate in the Shared Cost Parkway Tree Program. Based on the type of tree selected, crews will plant one of four types of trees for $55 or $95 in the spring or fall. Priority for this program will be given to homeowners whose ailing ash trees have been removed. Learn more about the Shared Cost Parkway Tree Program (pdf) on the City’s website or by calling the Forestry Division at 630-260-2122.

Spray

Michigan has just ok'd a new pesticide to try to use on these things, supposed to start spraying it at the end of April. Hopefully it works before the ash trees I have are hit...

What's the name of the spray and are you doing it by air or what. I'd love to get mine done and all my neighbors. MSU did a bunch of work in my woods. They cut a bunch of little trees down and took samples and a bunch of other stuff but I really don't know of there finding. Let me know what the name is and where I can get it.

I hope they test this wasp on ALL other types of beneficial insects. Sure, it takes time, but doubling the problem by disturbing the food chain even more doesn't make sense to me. Definitely sounds like it could develop into a government project..

WARSAW, Ind. July 21, 2008- A trap has detected the tree-killing emerald ash borer in northern Indiana's Kosciusko County, the state Department of Natural Resources said Monday.
The purple traps, which have been placed throughout much of the state, look like box kites and hang in trees about 12 to 15 feet off the ground. They are lined with glue and baited with manuka oil, which attracts nearby ash borers.
The insect was detected near Warsaw in Plain Township, which the DNR said has been placed under quarantine. Under the quarantine, ash nursery trees, ash logs and hardwood firewood cannot be transported out of the township.
"We continue to stress buying firewood at the camping destination and burning it completely before leaving the site," said Purdue University entomologist Jodie Ellis. "Much of the spread of emerald ash borer has been the result of unsuspecting campers moving firewood."
Kosciusko County also is under quarantine, so that ash products may move within the county, but not outside it.
Kosciusko is the 18th Indiana county where emerald ash borers have been confirmed, and part of a cluster of northeastern counties under quarantine. Other quarantined counties include Adams, Allen, DeKalb, Elkhart, Hamilton, Huntington, LaGrange, Marion, Noble, Porter, Randolph, St. Joseph, Steuben, Wabash, Wells, White and Whitley.
Large infestations of the green insect have killed millions of ash trees in Michigan, Ohio, and Indiana since the borer was first found in the United States in 2002.

The damn bug was first found in Detroit/Windsor in 2002, and I didn't see a dieing tree in my area until 3 years ago.

There are several hundred Ash trees within a mile of my home. And I don't know of even one still healthy one within that 1 mile, all are now dead or dieing.

I expect there will be no living Ash trees within several miles of me in just 2 more years.

We cut down the largest tree growing for several miles in any direction 2 years ago on my brothers farm 1/3 mile north of me. This tree, aged by growth rings was 142 years old, it was over 100" tall, 70' wide (widest point) and dbh of 44". It took 14 pickup loads to haul away the wood, and we didn't save stuff under about 2 1/2" to 3". It was the largest White Ash I've ever seen.

I wouldn't bet on ever cutting a larger tree than that one. But there are enough other pretty large Ash trees around that it led me to trade up to my 460.

A VERY sad situation, our country needs to enact & enforce the same kind of laws/standards toward other nations imports as we impose on our own exporters.

There were once American Chestnut trees in this area, I remember seeing the standing dead skeletons of a couple when I was a young boy. We also are still cutting up dead Elms in this area. And now I hear that they've found dieing Beech trees in Hudson Mi which is about 30+ miles west/northwest of me & we're starting to lose a few Oaks to Oak wilt.

Think of the diversity lost..........sickening.....
