Culturing Fruit Flies

I have been working on a recipe for culturing fruit flies
from instant mashed potatoes for about a year now with limited success.
I have been using a recipe for a while now, which uses instant potatoes. The
results are actually pretty good. I only need about 6 flies to start a thriving
culture. I found the recipe off of an excellent web site for every fish related
topic. It consists of:
1/2 cup instant mashed potatoes
1/2 table spoon of sugar
fill sterilized container with approximately 1" of above mixture
fill with water up to the top of the mixture (I usually add a little extra, not
too much standing water though).
Now add just a small pinch of dry yeast granules on the top of the media.
Add flies and cap the top of the container with some sort of sponge. (I use a
regular sponge that is used for washing the car only $.99, brand new of course
:) I also boil the sponge for about 10 minutes, just to be on the safe side.
If the mixture gets to dry I just add a little more water when needed.
If done in a large container the culture can get pretty large, too large at
The best media I have found to date was by accident. I was cleaning my tanks and
replacing filter and pre-filter cartridges, when I threw away my Hagen
pre-filter pad. I then continued to clean out my fly cultures waste (dead
carcasses, empty shell, etc.) into the same waste basket. I tied the bag closed
and left it. Not realizing what could happen, I left it there for about a week.
To my suprise, when I came home one day I started noticing little black things
running all over the place. When I took a closer look I realized what they were.
Not realizing where they were coming from I continued my investigation. When I
found the source ( the waste basket ) I was shocked to see hundreds of flies
still trapped in the bag. To make a long story short, I collected over 200 flies
in the next two days alone. The culture was tapped out after about 5 days of
heavy feedings to all tanks.
If anybody has any other media types that will boost fruit fly cultures please
Also, any tips on boosting an indoor daphnia cultures.
