Hal, The larvae I mentioned could be from several insects but the one we
favor is the Black Soldier Fly

Craig Sheppard and Larry Newton at Univ Ga have shown that the larvae are
not only a significant disposal system for a wide variety of putrescent waste,
including poultry manure, but that they are a significant asset in
themselves. They self-harvest when they are ready to leave the feeding troughs. The
larvae at that point are about 45% protein and 30% fat. The adults do not come
indoors, do not bite or sting, nor do the adults eat.
This means that they are not a pest. In fact, where the BSF larvae exist in
quantity the usual house fly will not coexist. So having BSF consume your
waste matter significantly reduces house fly populations for multiple reasons.
We have fed the harvested BSF larvae to poultry, fish and pigs with great
success as a supplemental source of protein and fat. So we have converted a
waste material into a feed source. And very little material would have to go
to the next step. In fact they can also convert your mortalities.

What kind of larvae are you talking about? At our farm we are composting
our manure because the heat kills any fly larvae, pupae, or eggs. Fresh layer
(poultry) manure is too strong for worms. If you used some kind of insect
to "pretreat" you would have to a way of seperating them back out from the
product that needs to go on to the next step.
