From a growth, nutrition and/or cost perspective, does the beetle chow have an advantage over a good pellet currently on the market?


Bump....

A little kid will fill up on popcorn but that doesn't mean it is nutritious. Are Japanese beetles good for the fish?


Still working on that. Moisture content just over 50%. Chitin content is part that needs to be parsed out from protein which I think will still be at least 2/3 (protein) of the dry weight. Hand cranked oil press does not get much oil out so will run through a larger commercial type to see if more oil can be separated out.

This summer a growth trial will be ran with Bluegill to see how they grow. Must conquer milling problem first. My gut feeling is the pelleted version will out perform popcorn.

Our local catalpa trees only have worms on them every few years. There are about six big catalpas in our neighborhood. Two or three trees had worms year before last. No worms at all last year.

CC,

I fished with catalpa worms a lot as a kid. They are awesome bait but I think you need catalpa trees.

I have a few trees and currently am growing some more in my window sill in the 4 season room to plant in June.

If you(or anybody else) want some northern Catalpa seeds, send me a PM. I would be happy to send you some.

Bill D.


I have had some years where Catalpa Worms can be harvested by the 5-gallon bucket full, but takes too much work. Harvest of that critter is also very irregular with some years giving almost nothing. The little parasitoid wasp has a hand in that.

You are starting to worry us a little Jim. eek

Jim,

How many pounds of beetles do you think you could come up with?

I might know a guy who could turn those into some r&d feeds.

I have a couple hundred pounds in freezers and will likely use all of that trying to work out a milling procedure.

If like last year, then thousands of pounds will be harvested although we lack storage capacity to keep that much in storage. Bulk density and drying are challenges we will be working on in the coming weeks. Our harvesting is not industrial scale.

I have funding to do the research now.

Maybe "toasting" them might be a better procedure than freezing. Farmers dry wet corn in propane fired dryers. Why not "dry" the bugs?

Where could one get the top for the trap? We had a bad infestation on our crepe myrtles last year. I would be interested in making a floating trap on the pond, where the trapped beetles would drop into the water.

I am familiar with the dryers as we used them for drying corn. We have been considering using one already. Killing the beetles first I think really needed as corn kernels do not crawl or fly out during the drying process.
