Nutri-Fly® Bloomington Formulation
Nutri-Fly® Bloomington Formulation is made to accommodate the requirements of large, communal Drosophila media preparation facilities as well as small, independent laboratories. Recipe can be doubled, tripled, etc. in the same batches to meet any media quantity requirements. For consistency, most ingredients* come from the manufacturers cited on the Indiana University, Bloomington Drosophila Stock Center website here. Sealed in single-use foil pouches, Nutri-Fly® BF is not only convenient but also robust, and guaranteed to make fresh and substantive food throughout its shelf-life of two years from delivery. Strict lot traceability procedures are employed to each ingredient, in every batch.
Ingredients Include: Quaker Yellow Cornmeal, Agar Type II, Tate and Lyle Corn Syrup Solids, Lynside Nutri Inactive Nutritional Yeast, ADM Soy Flour.
Directions: Empty entire contents of packet into a cooking vessel. Add ¼ – ½ specified RT H2O and stir out any clumps. 
Add remaining RT H2O and stir.
Bring to a boil, then immediately reduce heat and cover. Simmer for 10 minutes, stirring occasionally. Add specified propionic acid (1.0m)** quantity, (not supplied).
* Corn syrup solids have been substituted in place of light corn syrup.
** Tegosept (Cat # 20-258, 20-259, 20-266 / synonyms: methyl paraben; nipagen) may be used in addition to but not instead of propionic acid. Propionic acid is considered sufficient as a preservative and the use of tegosept is known to slow Drosophila growth rates in the larval and pupal growth stages and we therefore suggest it be used only when additional fungal protection is necessary, or to eliminate sporadic mold problems.

Nutri-Fly® Drosophila Agar, 100 Mesh
Our technical grade Drosophila agar (USP) is a staple ingredient in fly food. 100 mesh particle size. Lot-to-lot quality control processes assure consistency in your fly food.
Gel Strength Coefficient
Agar gel strength can vary from lot to lot. Since the gel strength is noted on the label of all Nutri-Fly® Drosophila agar, we strongly suggest that Drosophila media facilities seize the opportunity to use this information to ensure consistency in gelification of fly food. To do so, one must first “normalize” the food by noting the gel strength of an ideal batch. Then, use the following formula to account for varying gel strength to calculate the exact amount of agar you
want to use in subsequent preparations:
Current Agar Mass x Current Gel Strength / New Gel Strength = New Agar Mass
For example, if the recipe calls for 10g of agar and the gel strength of the agar used in the previous batch was 850g/cm2 and the agar that will be used in the new batch has a gel strength of 900g/cm2, you will need to adjust your recipe and add 10 x 850/900 = 9.44. So, to keep your food consistent, you would add only 9.44g of agar instead of the 10g of agar that the recipe calls for.

Tegosept
Apex brand Tegosept is widely used as a fly food preservative. Odorless, tasteless and non-toxic (sanctioned for food use), Apex Tegosept is active at low concentrations against a broad spectrum of micro organisms. Tegosept may be used in addition to but not instead of propionic acid. Propionic acid is considered sufficient as a preservative and the use of tegosept is known to slow Drosophila growth rates in the larval and pupal stages and we therefore suggest it be used only when additional fungal protection is necessary.
