Japanese Beetles are social insects. They will come in great numbers to the proper pheromones and floral scents. Gardeners cuss them when hundreds of them congregate and they strip every leaf off of a prized grapevine or rose or raspberry bush.
Their attraction to pheromones and floral scents are used to trap them but I think they can be used for a higher purpose.
Picture in your head a lake with a few, lunker bass. Also picture in your head grassy meadows, perhaps golf courses or pastures or parks downwind of that lake. Picture in your head docks for boats.
Now, picture in your head one dock that has several Japanese Beetle traps, sans collection bags, tack to its side. Japanese Beetles emerging from the sod would follow the siren song of the pheromones to the dock. They would smack into the yellow "target" and tumble into the water....by the hundreds, perhaps thousands. And what do you suppose would lie in wait for those protein and fat laden morsels (piscina Snickers Bars, if you will). I propose that it would not be vegetarians.
The second use would be to control invasive alien plants like Multiflora Rose. As noted earlier, Japanese Beetles like roses...so why not put the lures, again without the collection bags, in Multiflora Rose specimens?

Our trash container lost the hinge-pin on one side.
Mrs ERJ figured out a way to get it through one more week.
