Flies are well-suited for survival and reproduction during the warm season. However, when raising flies artificially in autumn, there are several important factors that need special attention to ensure their health and productivity.
First, temperature control is crucial. Autumn temperatures typically range between 20°C and 30°C, with an average of around 25°C. In some regions, temperatures may drop below 20°C, which is not ideal for fly breeding. The optimal temperature range for fly breeding is usually between 20°C and 35°C, with the best conditions around 30°C. In areas where temperatures fall below this range, it's important to implement heating and insulation measures. Close doors and windows as needed, especially during colder periods. At midday, when temperatures are higher, you can open windows for ventilation, but not for too long—usually about two hours. The exact duration depends on local weather conditions. If high temperatures persist, you can extend the window-opening time. Additionally, using fans or adding insulation can help maintain a stable environment and remove stale air, ensuring the flies remain healthy.
Second, humidity control is equally important. After the rainy season, humidity levels in southern regions tend to be quite high, which can lead to digestive issues in flies. To manage this, you can sprinkle lime or ash on the ground to absorb excess moisture, or place desiccants in the room. It’s also essential to regularly check the hygrometer in the morning, afternoon, and evening. The ideal relative humidity for fly culture is between 50% and 70%. If the level goes beyond this range, the methods mentioned above can help restore balance.
Third, water management should not be overlooked. Although water consumption by flies decreases in autumn compared to summer, it's still important to monitor both the quantity and quality of water provided. Since we often add brown sugar to the drinking water, it's essential to change the water regularly. Flies drink from sponges, and if the water isn’t changed frequently, it can become contaminated with waste and degrade quickly. Ideally, the water should be changed at least once every three days to maintain hygiene and prevent disease.
By carefully managing temperature, humidity, and water supply, you can create a favorable environment for fly breeding even during the cooler autumn months. These practices not only support the health of the flies but also improve the overall efficiency of your breeding operation.
