The housefly, *Musca domestica*, is a common insect known for its rapid life cycle and adaptability to various environments. Understanding its morphology and behavior is essential for effective breeding and management.
**1. Morphological Characteristics**
*Musca domestica* undergoes complete metamorphosis, passing through four distinct stages: egg, larva, pupa, and adult. Each stage has unique features that contribute to the fly's survival and reproduction.
**2. Living Habits**
- **Lifespan**: The number of generations per year varies depending on environmental conditions. Under controlled temperatures, houseflies can reproduce continuously throughout the year.
- **Development Time**: The duration of each life stage is highly dependent on temperature. At 25–35°C, the entire life cycle takes only 10–15 days. Eggs hatch within less than a day, larvae develop for 4–6 days, pupae take 5–7 days, and adults live up to 1–2 months.
- **Activity Patterns**: Adults are diurnal, preferring to be active outdoors during the day and resting in shaded or warm areas at night.
- **Breeding Behavior**: Flies begin mating and laying eggs 2–5 days after emerging. In commercial settings, breeding cycles should be managed carefully, with each batch removed after 20–25 days.
- **Feeding Preferences**: Adult flies feed on high-protein liquids, such as milk powder or brown sugar solutions. These diets can extend their lifespan to over 50 days. Adding fruits or vegetables to the feed can enhance egg production. Larvae, on the other hand, prefer decomposing organic matter and thrive on fermented artificial feeds.
**3. Environmental Requirements**
Temperature and humidity play critical roles in the development of *M. domestica*. Optimal conditions for larvae are 25–35°C, while adults perform best between 20–30°C. Humidity levels should be maintained at 50–80% for adults, and the culture medium must remain moist but not waterlogged (50–60% moisture content). Extreme temperatures above 40°C can cause larvae to escape, and temperatures over 45°C are lethal.
**4. Cage Fly Technology**
To scale up fly farming, several key considerations must be made:
- **Farming Scale**: A daily output of 100 kg of larvae requires approximately 300,000 adult flies. This involves multiple breeding units to ensure continuous supply.
- **Facility Design**: Indoor rearing rooms should maintain 24–30°C and 50–70% humidity. Fly cages, typically 50 cm in size, are essential for housing adults and should include feeding and egg-laying trays.
- **Feed Preparation**: Egg-laying media should be nutrient-rich and aromatic to attract females. Adult diets often consist of milk powder and brown sugar, while larvae are fed fermented organic waste like wheat bran and fishmeal.
- **Management Practices**: Regular monitoring of temperature, humidity, and feed quality is crucial. Eggs should be collected regularly, and larvae separated promptly to avoid overcrowding and loss of control.
**5. Breeding and Maintenance**
After 20–25 days, adult flies will lay large quantities of eggs. It’s important to select healthy eggs from the 6th to 10th day and provide them with high-nutrient feeds. Maintaining clean, well-ventilated spaces and controlling breeding populations are essential to prevent infestations in the wild.
**6. Daily Management Schedule**
A typical routine includes:
- Morning: Feed adults, change water, and collect eggs.
- Midday: Monitor temperature and humidity, and add water if needed.
- Evening: Collect hatched eggs and check feeding trays.
- Cleaning: Food trays and sponges should be cleaned every two days, with replacements done every 20–30 days to maintain hygiene.
By following these practices, fly farming can be both efficient and sustainable, providing valuable resources for agriculture, animal feed, and ecological research.
