Default Pretty insect but bad news - Spotted Lanternfly

Has been spotted in PA (pun intended).

Be Prepared for the Invasive Spotted Lanternfly, Entomologists Warn ? Entomology Today

Quote:
The brilliant colors–– red, black, and white — of the spotted lanternfly reveal one of the reasons why it is difficult to control by using natural enemies. Its hues are warning colors that alert predators to the fact that the lanternfly is toxic due to poisons called cytotoxic alkaloids, which it metabolizes from some of its host plants.
Quote:
Native to northern China, the spotted lanternfly has spread to other parts of Asia, notably Korea and Japan. It has caused considerable damage in those countries, which is why state authorities in Berks County, Pennsylvania quarantined five townships and issued an alert document to help people identify the pest.

Even though the lanternfly remains confined to a small area of Pennsylvania, pest managers best be ready to identify it and be familiar with its biology and the control methods used elsewhere.
Sooo Why can't they just kill the entire colony with a local spray or something. I'm not one to grab for the bottle but surrendering a few of the goodies along the way to eliminate something like that for the good of one and all certainly sounds the most beneficial way to go in the long haul. Doubt if anything else would go extinct if it's in such a small area. The goodies would more than likely filter back in wouldn't they?

The article I linked said that so far the sprays don't seem to work long term.

This webinar has some good pics of what the pest looks like during its life cycle.

Pesticides seem to be ineffective for long-term control, and lanternflies can quickly repopulate vineyards after spraying.
Wonder if they've tried spraying again and again so many days and-or even weeks apart like we must do to eradicate the ever populating spider mites upon our house plants.

That sounds like decades ago when they were trying to control gypsy moths. They would fly overhead with crop dusters and spray all of suburbia with pesticides. It wasn't very popular, as I recall.
