The emerald ash borer is a small green metallic beetle that was detected first in the United states in 2002 in Detroit said Ryan Armbrust a forest health specialist with the Kansas Forest Service.
Trees that have been invaded by the emerald ash borer have a thin canopy Armbrust said. As that tree loses leaf material it will try to regain some of it by sending out new shoots lower on the tree.
and stress from the emerald ash borer is woodpecker damage because the beetle larva is a food source for the woodpecker.

While all of the animals lost weight as a result of nematode infection the degree of weight loss varied widely:
and found that sheep with the highest tolerance to nematode infection produced the most offspring while sheep with lower parasite tolerance left fewer descendants.

The UW Arboretum long a refuge for Wisconsin's native plants and animals is confirmed the first site for Amynthas agrestis an invasive worm believed to have arrived in the United states from its native range in Japan
Williams and members of the arboretum staff confirmed the earthworms'presence in the fall of 2013 checking regularly in the spring to see
if the worm's egg cocoons survived a particularly harsh Wisconsin winter. That appears to be the case according to Brad Herrick arboretum ecologist
--and doing our best to stay clear of the areas where we have found the worms.
In most of Wisconsin Amynthas is not alone among invasive earthworms. The last glacier which covered all but the southwestern corner of the state as recently as 20000 years ago wiped out all native earthworms.
The earthworms familiar to most Wisconsinites are introduced European species by the first settlers. While they too can damage natural landscapes European species rarely reach numbers like their Asian counterparts.
Amynthas'lifecycle is completely different from European species of earthworms Williams says. It breeds en masse
and is constantly dropping cocoons. Where the cocoons hatch at the soil surface you'll see what looks like small filament hairs moving on the soil surface in large numbers.
The grayish Amynthas is darker in color than pale pinker European earthworms grows to eight inches long
and has earned common names like crazy worm snake worm and Alabama jumper by flopping and wriggling vigorously when handled.
Unlike the raised ridged band (called a clitellum) that is found near the middle of European earthworms the Amynthas clitellum is smooth flat to the worm's body and a milky white to gray in contrast to the rest of the worm.
The crazy worms mature in just 60 days or so allowing populations to double during Wisconsin's warm months
Our native plant communities developed without the presence of all these hungry worms. The Amynthas eat so much that they take away the spongy surface organic layer that those plants need for nutrients.

#Pesticides make the life of earthworms miserablepesticides are sprayed on crops to help them grow but the effect on earthworms living in the soil under the plants is devastating new research reveals:
The worms only grow to half their normal weight and they do not reproduce as well as worms in fields that are sprayed not.
Pesticides have a direct impact on the physiology and behavior of earthworms a Danish/French research team reports after having studied earthworms that were exposed to pesticides over generations.
We see that the worms have developed methods to detoxify themselves so that they can live in soil sprayed with fungicide.
They spend a lot of energy on detoxifying and that comes with a cost: The worms do not reach the same size as other worms
and we see that there are fewer of them in sprayed soil. An explanation could be that they are less successful at reproducing
The researchers set up an experiment to study the behavior of the earthworm species Aporectodea caliginosa.
They moved two portions of farmed soil with worms into the lab. One portion was taken from a local organic field the other from a local conventionally cultivated field that had been sprayed with fungicide for 20 years.
In the laboratory the researchers could see how the fungicide-exposed worms adapted to the toxic environment.
Over generations the worms have developed a method to detoxify themselves. The fungicide increased metabolism rate in the worms both the adapted worms and the not adapted worms.
In the not adapted worms we saw that their energy reserve of glycogen was used faster.
Contrastingly only in the adapted worms we saw that amino acids and protein contents increased suggesting a detoxification mechanism.
They also increased their feeding activity possibly to compensate for the increase in energy demand the researchers said.
Often there are 2--3 times more earthworms in unsprayed soil than in sprayed soil. The reason for this may be that earthworms in sprayed soil do not reproduce as successfully as worms in unsprayed soil
because they need to spend more energy on detoxifying the researchers say. They also weighed the worms in the experiment
and found that the worms exposed to fungicide weighed only half of the worms in organic soil.
Worms in organic soil had an average weight of 0. 6 grams worms in conventionally cultivated soil had an average weight of 0. 3 grams.

Roundwormsthe banana variety Yangambi km5 produces toxic substances that kill the nematode Radopholus similis a roundworm that infects the root tissue of banana plants--to the frustration of farmers worldwide.
The parasitic nematode Radopholus similis is the invisible nemesis of the banana plant says Professor Dirk De Waele:
The nematodes are invisible to the naked eye but they can penetrate the roots of banana plants by the thousands.
Combating nematodes isn't easy adds Professor Swennen: Synthetic pesticides are toxic and expensive. Moreover pesticides usually do not actually kill the nematodes they just temporarily paralyze them.
Nematodes can also build up resistance to pesticides. We have wondered always how the Yangambi km5 fights off roundworms.
This study offers an answer. While the Grande Naine is very susceptible to nematodes other varieties are known to be resistant to them.
Enter the Yangambi km5 a variety first grown in the 1950's at a Belgian research station in Yangambi DR Congo.
Metaboliteswith colleagues at the Max Planck Institute for Chemical Ecology (Germany) the KU Leuven researchers identified the metabolites that kill the nematodes.
We found nine different nematode-killing metabolites in Yangambi km5. These metabolites are produced also in the Grande Naine but much more slowly and in lesser quantities.
In that banana variety the nematodes win the fight. The researchers'findings were published in a recent issue of the journal PNAS.
This method could also be applied to other crops and other species of nematode. Nematodes pose a growing threat to rice production in Asia for example.
Our findings also provide the industry with perspectives to develop a generation of new pesticides against nematodes.

#Beneficial insects, nematodes not harmed by genetically modified, insect-resistant crops, studies showa large body of literature has shown that genetically-modified plants that produce proteins from the bacterium Bacillus thuringiensis (Bt) to protect themselves from insect pests have little to no effect on a wide range of nontarget insects.
Now two new studies using more exacting methods show that Bt crops have no negative effects on two beneficial insect predators or on a beneficial entomopathogenic nematode.
Nematode Heterorhabditis bacteriophora Shelton and his colleagues used similar methods and found that an important nematode predator was harmed not
when it ingested another Bt protein. For this study resistant caterpillars were fed Bt broccoli and then exposed to Heterorhabditis bacteriophora a beneficial nematode that preys on insects.
The researchers found that the virulence reproductive potential and time of emergence of the nematodes that consumed Bt-fed caterpillars were affected not significantly compared to nematodes that did not ingest the Bt protein.
This is the first report we are aware of in which a nematode predator has been tested in such detail against a Bt protein Dr. Shelton said.
Together these two studies add to the scientific literature demonstrating that Bt plants can control targeted insect pests
