Like the illusion of Wall Street, with its vast and powerful investment banks, now shuttered, China too is an illusion perpetuated by the Globalists that gave us the 15,000 mile Caesar salad, poisoned cat food and lead based paint on babies' pacifiers. Like the illusion that money would come from thin air to always push housing prices higher, China has spent a generation pursuing its illusion. Pursuing an unattainable dream to be like the West, while 6000 years of its carefully shepherded top soil blows into the sea.

Seems like what you need is window screen. Maybe you could make some screen panels that you could hang on the frames you've got. Then at the end of the season, you could take the panels off and store them for next year. It'd be more work and cost at first, but you should be able to get many years of service out of them if you stored them carefully.

SPG and Cop, thanks for these terrific suggestions and that great website link. That vendor offers some other stuff that might be of even greater interest, such as aluminum screening (probably a lot more durable). And some of the widths are wider than 36 inches---up to six feet and more. I'll have to think of how to modify my frames (perhaps using SPG's idea) to accommodate this possibility.

The material I attach to the sides of the tree structures can stay on year-round, since there'll be no weight of snow and ice on them. Removable frames would be necessary only for the tops.
As for the grape structures, since they're fairly small maybe the window screening could support the weight of the small snowfalls we occasionally receive---if I add some more bracing, that is.

F&*^ M*!!! I've got Jap Beetles. Found 5 of them on my plum. Wondered why i had new foilage damage. I might as well pull the plug on this whole operation... I can't fight off Chafers and Jap Beetles. I've never seen them here before. I wondered why a house about a mile away had to Jap beetles traps set up in his yard.

This things are fat and fast! Usually Chafers i can grab and drop on the ground and squish. These things fly before landing. Looking more and more like i'm going to have to get rid of the plums.
edit:This is a crock of $hit! I'll just make sure i watch what trees they like and i may just get rid of those. I also found a fat one on my grape vine!

My sister lives out in Omaha...got me thinking if they have Jap beetles out in NE (maybe i can move there!)...so here is what i found:
Code:
The most probable cause for this rest area becoming infested with Japanese beetle was due to infested B & B nursery stock being planted in the fall of 1984. A portion of the rest stop which is in turfgrass and under irrigation has been treated with insecticides for the past few years. The following shows the trapping history of Japanese beetle statewide in Nebraska:
1999:    659 Japanese beetles
1998:    131 Japanese beetles
1997:    218 Japanese beetles
1996:    173 Japanese beetles
1995:    353 Japanese beetles
1994:    138 Japanese beetles
1993:    87 Japanese beetles
1992:    54 Japanese beetles
1991:    61 Japanese beetles
1990:    163 Japanese beetles
1989:    608 Japanese beetles
1988:    381 Japanese beetles
1987:    318 Japanese beetles
1986:    112 Japanese beetles

Looks like they have just a few and they came from nursery items imported into the state. Looks like they are trying to (may have by now) eradicate them all.
I wonder how many barrels of SEvin i can store in my basement! Better invest in a gas mask for me..i wonder if they sell them for children!

Japanese beetle larvae are the fat white C-shaped grubs found under turf and grassy lawns. Heineken, perhaps these beetles are so prolific where you are because of lots of nearby lawns? I have only seen a few so far this year but I dug up most of my lawn last year.
/sarcasm on
Since they can be controlled by handpicking, after TS has HTF, it will be part of an exciting new entertainment package, gathering inedible beetles off of plants in a large garden again and again and again....

I think you might be right...this is what we did as kids when tasked (every day) with taking care of the garden. Put a couple coffee cans around your garden half filled with kerosene gas or such...go out at the hottest part of the day and hand pick them off the plants and chuck em in the cans...do this for potato bugs as well...JB's are like fleas and mostly localized....break the chain and reduce the populations like fleas...

Frank, are you sure what you're finding is the Japanese beetle? (I don't normally think of them as "fat and fast.") But, I guess you've seen enough pictures of 'em to know what you're seeing.
I can understand how devastated you must feel.
I wouldn't cut down any fruit trees yet, though. Give it a few years at least and see where this is going. You might end up with a less severe infestation in so cold a climate as yours. You might still be able to get fruit---that's the goal, after all, not perfect leaves.
And, given the success I've had with my protective structures, don't you feel they pose an option for you? Admittedly, you might have to reduce the number of fruit trees and grape vines you have.

The county-by-county map is very interesting. I've seen similar ones but never quite so detailed as yours. Clearly, once the JB becomes fully established along that solid, purple wavefront, there's no getting rid of it; this is proven by the fact that every county east of the wavefront is purple (except for northern Maine, which is probably too cold for the beetle to survive---or maybe they just haven't gotten there yet). As I understand it, the wavefront advances each year by approximately the distance the beetles can fly in a season, five miles.
Kids with coffee cans filled with kerosene would have little meaningful effect, any more than an old woman with a fly swatter could control a swarm of locusts. In my case, those kids would have to be on duty next to each fruit plant all day long every day from mid-June to mid-August to protect those individual plants.

None of these folk remedies work. I've tried most of them. No matter how many individuals you kill, a whole new fresh horde of beetles shows up every day for literally two months on end, in cases of a bad infestation.
There is a perception by some that the JB isn't a problem in wilder areas with few lawns. This is untrue. Right now JBs are feeding by the thousands on tall weeds in a large field I have. I've seen them feeding on sassafras trees deep in the woods. They love wild blackberries. Once established, they aren't dependent on human activity at all. They don't need our food plants, but they do prefer our food plants.

100% sure...

Haven't found anymore yet...

Always thought it was too cold for them here...

Update:

As the pics I posted show, some of the structures have white tulle covering them and some of them have green tulle ("emerald green" is what PaperMart calls it).

Although the white stuff has developed large rents and holes, so far the green tulle has held together well enough to meet my personal criterion of "acceptable." I'm wondering whether the color could have some effect on UV stability. Anybody have any thoughts on this?

Unfortunately, the green is available only in a 52- to 54-inch width; the white is available in a width twice that. Still, the green is large enough to be usable.

I will probably be buying the window-screening material and installing it over the winter on at least some of my protective structures.

So far I've still had complete success keeping Japanese beetles (and all other seriously destructive bugs) off my grape vines and the one fully protected plum tree. The JB season will start to fade in about three more weeks. So I'd rate the experiment as a success, although some more refinement is needed.

In June I harvested my first crop of Methley plums, and boy were they tasty!

Bottom line: You can grow fruit successfully and without any insect problems or the need for any pesticides, if you're willing to go to the effort and expense of building protective wooden frames around them and covering the frames with a barrier material that admits sufficient light, rainfall, and air movement (either tulle or window screening or a combination of the two, such as window screening for permanent use on vertical or slanting parts of a frame and tulle for seasonal use on horizontal "roof" parts of a frame).

Frank, what's going on with your beetle attack?

I'm bumping this up because there's an error in some of the immediately preceding discussion. I remembered that you can't completely enclose most types of fruit trees in permanent bug-excluding netting (like window screening) or you'll also exclude pollinators, and get no fruit. (It's easy to forget this when you're in the throes of battling Japanese beetles.)

Therefore, what I suggest for anyone interested in pursuing this sort of installation is permanent window screening on two (or possibly even three) of the four sides of a tree-type frame and tulle on the other sides and on the top. This would greatly reduce your annual expense and labor for replacing tulle. The tulle gets applied after the pollination period is over, of course, and removed at the end of the bug season.

My green tulle is still holding up great on the grape structures. I've had to replace sections of the white tulle on the plum-tree structure.

Haven't seen any for over a week. Killed maybe 5, and saw a few more. Not sure what to think. I guess Madison, WI is have a horrible time with them.

Going to be hard a ever growing population with bugs like these around.

You might want to report your JB observations to your extension agent, Frank. If you're on the front lines of the JB advance, he or she is probably monitoring the situation pretty closely. Perhaps your county is engaged in eradication efforts. I don't know how effective they are, but attempts are made.
