The vestigial-winged fruit fly (scientific name: Drosophila melanogaster, mutant strain) is a classic model organism for genetic research. Its wings are underdeveloped, limiting its flight ability, which makes it easy to breed and observe. This strain is widely used in teaching, scientific research, and pet rearing (e.g., feeding reptiles and small fish). Vestigial-winged fruit flies are an excellent food source for carnivorous insects such as juvenile springtails and praying mantises. The fruit fly bottle contains all the necessary food for the fruit flies, so no additional food or water is required for storage. Vestigial-winged fruit flies are a naturally deficient variety, so there will be no issues with them flying around.
Care points:
- Breeding container:Use a breathable plastic or glass container with a lid that has a fine mesh or ventilation holes to prevent escape and maintain ventilation.
- Basic formula: Mashed ripe banana (or apple), oatmeal, a little vinegar (to inhibit mold), mixed with water to a paste-like consistency.
- Temperature and humidity: Optimal temperature 20-25°C, avoid above 30°C or below 15°C, humidity maintained at 60-70%.
-
Reproduction cycle: Female flies lay eggs on the surface of the culture medium; larvae (maggots) pupate in approximately 5-7 days, and adults emerge after 10-14 days.
Note: "Vestigial wings" does not mean the fruit fly is completely immobile. While vestigial-winged fruit flies have poor flight ability, they can still jump or glide short distances, especially with increased activity at higher temperatures. If the container is not covered or the ventilation holes are too large, they may still escape.
