Emerald how to get rid of ants in house home remedy ash borer may have met its match UIC Today

Since the emerald ash borer was first found feeding on how to get rid of ants in house home remedy trees in southeastern michigan in 2002, this asian invader has been responsible for the death of how to get rid of ants in house home remedy 30 million trees in the northeastern U.S. And canada. In chicago, where the emerald ash borer is already destroying trees, 17 percent of the street trees are ash—85,000 trees, with an estimated 300,000 more ash trees on private property.

In this study the researchers wanted to see if native how to get rid of ants in house home remedy bark-foraging birds, including woodpeckers and nuthatches, were feeding on the emerald ash borer. They hoped that unlike other exotic invasive species which run how to get rid of ants in house home remedy amok in new regions because of the lack of predators how to get rid of ants in house home remedy to keep them in check, the emerald ash borer might meet its match in native how to get rid of ants in house home remedy predators—bark foraging birds like the woodpecker and nuthatch.

This kind of “bio-control” would be as, or perhaps more, efficient than other methods to slow the spread of this how to get rid of ants in house home remedy pest, said flower. Chemical treatments are expensive and may cause harm to trees how to get rid of ants in house home remedy and other fauna, and the introduction of an ash borer predator from its how to get rid of ants in house home remedy native range in asia might bring with it a host how to get rid of ants in house home remedy of new problems, he said.

One of the ways a predator can respond to a how to get rid of ants in house home remedy new abundant food source, according to flower, is a functional response: the woodpeckers alter their behavior in a way that allows how to get rid of ants in house home remedy them to find emerald ash borers more efficiently and then how to get rid of ants in house home remedy consume them more than other prey.

One woodland area being monitored lay behind dempsey middle school how to get rid of ants in house home remedy in delaware, ohio. The researchers enlisted the help of schoolchildren to do a how to get rid of ants in house home remedy precise accounting of bug and woodpecker activity in the area, said christopher whelan, an avian ecologist with the illinois natural history survey, UIC adjunct assistant professor of biology and a co-author of the study.

When emerald ash borer larvae emerge from eggs laid on how to get rid of ants in house home remedy the tree, they burrow in and eat their way through the phloem how to get rid of ants in house home remedy layer of the tree, the vascular system that delivers water and nutrients from root how to get rid of ants in house home remedy to branch. The insects create characteristic serpentine galleries that cut this vascular how to get rid of ants in house home remedy system, starving the tree. Eventually mature adults exit the tree to start the process how to get rid of ants in house home remedy again.

A section of trees in the stand behind the school how to get rid of ants in house home remedy was cut down for examination each year for two years. The students searched for and painted all the holes they how to get rid of ants in house home remedy found in the bark of each tree—a different color each for large round woodpecker holes, for the characteristic crescent-shaped holes mature emerald ash borers make exiting a tree how to get rid of ants in house home remedy and for holes made by other insects.

Paint seeped through to dye the stem beneath, and after the bark was stripped the students could identify how to get rid of ants in house home remedy woodpecker holes that penetrated into emerald ash borer galleries, or into holes made by other bugs. The students tracked the fate of each bug that had how to get rid of ants in house home remedy been in the tree. Instead of relying on a statistical estimate of the insect how to get rid of ants in house home remedy population and thus the food source available, every bug and its fate were accounted for.

Another type of predator response to a new food source how to get rid of ants in house home remedy is a numerical response: the numbers of the predator, in this case woodpeckers and other bark foraging birds, increase either because they were moving into the area or how to get rid of ants in house home remedy reproducing more successfully.

In a related study, researchers at cornell tracked the movement of emerald ash borer how to get rid of ants in house home remedy from detroit and around the great lakes using a citizen how to get rid of ants in house home remedy scientist data base—the project feeder watch—which showed that the numbers of three woodpecker species and how to get rid of ants in house home remedy the white-breasted nuthatch, the important bark foraging birds in this region, increased as the emerald ash borer increased. “but that study examined the bird population response and didn’t tell you what the birds were doing there,” said flower.

Very little is known about emerald ash borer habits in how to get rid of ants in house home remedy its native environment, its natural predators, or how its population is controlled, said flower. Slowing its course may give researchers time to learn more how to get rid of ants in house home remedy about how it can be controlled.
