Aggressive Parasitoid Wasps Will Soon Wage War On Emerald Ash Borers
The emerald ash borer has been mentioned before. These bugs are invasive to the United States, and they are continuing to move from state to state. Ash borers can destroy ash trees in no time at all. Some state forestry officials are clueless as to how these insects could be eradicated, but officials in the state of Wisconsin are putting a bold eradication plan into action. The plan involves releasing aggressive insects into forests with the hopes that they will destroy the ash borers before they kill any more ash trees.
Ash borers were found in Wisconsin eight years ago, so they are fairly new to the United States. However, eight years has been more than enough time for forestry officials to take notice of the many ash trees killed by ash borers. In Green Bay, Assistant City Forester, Brian Pelot, had an idea to use wasps as an insect-pest control method. A few days ago, Pelot released four hundred tiny, stingerless, and fierce Russian parasitoid wasps into the forest around Baird Creek Trail. Of course, the wasps cannot sting the ash borers, but these wasps will not hesitate to attack adult ash borers, and if an adult does not work out, then these parasitoid wasps will go after the eggs that the ash borer lays on ash trees.
The parasitoid Russian wasps are perfect for hunting and killing ash borers. Ash borers, their larvae and their eggs are the main food source for these wasps. The Russian wasps will not go after any other type of insect, they will not consume any other insect, and if ash borers were not in the United States, then the wasps would die.
After officials with the US Department of Agriculture learned about the destructive ways of the ash borers, they were welcome to any eradication ideas. Last year the USDA approved the “wasp-plan”, and the department is even paying for the project. Early research shows that the wasps are fifty to ninety percent effective. Hopefully, America will, one day, be free of emerald ash borers once again.
Do you think that the wasp plan will work? How many years must pass until researchers will be able to determine this method’s efficacy?
