hi.
i got this info from some site/forum in europe.tried to find it to give credit where i found but couldn't remember where i got from. guess i've been sniffing too many yeast fumes. i have yet to try the yeast but next time i make up a batch will try the soft yeast. plus it did answer why my medium went gooey a few times.

Some hints:
The flies should not lay too much eggs per bottle, because first the food mixture will get liquid, second the development of the fly will bedisturbed and delayed, and third too small flies will hatch. We use foam-rubber to stuff our breeding-bottles. The best receipt to get super-producer-flies is to give them a bit yeast in the bottle (from the "yeast-cubes" you can buy in every supermarket, not the "dry yeast". Add some drops of water, so that the yeast gets creamy, but not too liquid, otherwise the flies will stick on). Give them one or two days to eat the yeast (The females will become fat !) and on the third day they lay enough eggs for one bottle in one hour - on every food you give them! Add toilett paper or filter paper to the bottles if you are breeding flightless-flies.
Don't let the cultures get too old (see last message).
