Ingredients

• 100g cornmeal – the main carbohydrate source
• 30g active dry yeast – to encourage fermentation and nutrition
• 50g powdered sugar – provides energy
• 10g agar powder – to solidify the medium
• 1 liter water – for hydration
• 5g methylparaben powder (optional) – as a mold inhibitor
• 2g propionic acid (optional) – to reduce bacterial growth
• 1 teaspoon vitamin C powder (optional) – enhances nutrition

Equipment

• Large saucepan or pot
• Measuring cups and spoons
• Mixing bowl
• Stirring spoon or whisk
• Heat-resistant containers or culture bottles
• Heat source (stove or hot plate)
• Protective gloves and apron (recommended)
• Thermometer (optional but helpful)

Instructions

1. Combine dry ingredients: In a mixing bowl, thoroughly mix the cornmeal, powdered sugar, agar powder, and yeast.
2. Boil water: Pour 1 liter of water into a saucepan and bring it to a boil over medium heat.
3. Add dry mix to boiling water: Slowly sprinkle the dry ingredient mixture into the boiling water while continuously stirring to avoid lumps.
4. Simmer and thicken: Reduce heat to low and keep stirring for about 5-7 minutes until the mixture thickens and the agar powder dissolves completely.
5. Cool slightly and add preservatives: Remove the pot from heat. If using, stir in the methylparaben powder, propionic acid, and vitamin C powder for extended shelf life and added nutrition.
6. Pour into containers: While still warm but not hot, pour the medium into your culture bottles or containers to a depth of about 1-2 inches. Avoid overfilling.
7. Let the medium set: Allow the medium to cool and solidify completely at room temperature. This usually takes 1-2 hours.
8. Inoculate with fruit flies: Once the medium is set and cool, introduce your fruit flies into the containers. Make sure to cover containers with breathable lids or mesh to prevent escape while allowing airflow.

Tips & Variations

To prevent contamination, always use clean equipment and handle the medium with sanitized gloves.

You can substitute cornmeal with wheat or oat flour if needed, but cornmeal tends to produce the best results for fruit fly cultures.

Adjust the amount of yeast based on how rapidly you want the population to grow. Less yeast slows the process, which might be useful for longer-term cultures.

For a fruit fly medium without agar, you can use mashed banana or pureed fruit as a base, but this will require more frequent media changes due to spoilage.

Serving Suggestions

This fruit fly medium is best served fresh and used within 1-2 weeks for optimal results. If you notice mold or discoloration, it’s time to replace the medium.

Keep the culture containers in a dark, warm place between 20-25°C (68-77°F) to promote growth. Avoid direct sunlight as it can dry out the medium and stress the flies.

When harvesting fruit flies as pet food or for experiments, gently shake the containers to encourage flies to move to the top, then collect them using a fine brush or aspirator.
