Tiny insect menace chokes trees across Cape Cod
Tiny insect menace chokes trees across Cape Cod
Its common name the crypt gall wasp is like something out of a horror movie, but for property owners, the evil it wreaks is all too real.
Hordes of the tiny wasps deposit their eggs in the trees' new spring growth. The larvae grow inside the wood and form swelled chambers known as galls.
A year later, the adult wasps measuring only 5 millimeters emerge through pinprick holes in the wood and repeat the cycle over again, cutting off the system that distributes nutrients throughout the tree.
Starved of food, twig growth slows, leaves turn brown and eventually, if the infestation continues unabated, the tree may die.
Even though much is known about the tree killing culprit, much is still a mystery, including whether it is a native or wash ashore.
"So little is known about the life cycle," Russ Norton, educator in horticulture at the Cape Cod Cooperative Extension, said.
Norton, who is monitoring a research site in Nickerson State Park in Brewster, and other researchers are working to fill in those gaps.
Recently, workers with Arborjet, a Woburn company that tests and sells tree injection systems and insecticides, took a stand against the crypt gall wasp in Dennis Village Cemetery, a setting seemingly made for the fight against the pernicious pest with the deathly name.
Arborjet is working with University of Massachusetts Amherst professor of entomology Joseph Elkinton and one of his graduate students to study the best ways to deliver insecticide that will stop the wasps in their tracks.
Researchers are not even convinced the species has been correctly identified, Elkinton and Arborjet officials said.
"We're starting from square one with this insect," Elkinton said.
Widespread damage from the wasp became apparent on Martha's Vineyard cheap jerseys a couple of years ago, he cheap nfl jerseys said.
But, while a similar infestation on Long Island crashed after only three years, the outbreak on the Vineyard has lasted longer.
On Cape Cod, property cheap nfl jerseys owners and arborists started seeing widespread damage in 2012.
"You probably don't even see the symptoms for two years," Peter Wild, CEO and founder of Arborjet, said.
At the Dennis Village Cemetery, Arborjet's Don Grosman demonstrated how the injection systems use the tree's vascular system to transport chemicals to fight the wasps, Grosman said.
A small black plug called an arborplug is inserted wholesale nfl jerseys into holes drilled into the trunk, he said.
A needle wholesale jerseys attached to a pressurized reservoir is then connected to the plug, forcing the chemicals into the tree's active tissue. Environmental Protection Agency.
Unlike spraying or other methods, injecting the chemicals keeps them contained within the tree and out of the surrounding environment, Grosman said.
"We pride ourself in that we put everything into the tree," he said.
Even so, only a small amount of each product is required, he said.
For a tree with a 20 inch diameter, only 8 grams of the solution is used, Grosman said.
