CATDOLL: When will the maggots in the refrigerator hatch?

1. When will the maggots in the refrigerator hatch?

The external factors that affect the growth and development of pupae mainly include:

① Temperature: After the third-instar flies mature, they tend to pupate in a slightly lower temperature environment. However, when the temperature is below 12°C, the pupae stop developing; when the temperature is above 45°C, the pupae will die. Within the appropriate range, as the temperature rises, the pupal period shortens accordingly. At 16°C, it takes 17 to 19 days; at 20°C, it takes 10 to 11 days; at 25°C, it takes 6 to 7 days; at 30°C, it takes 4 to 5 days; at 35°C, it only takes 3 to 4 days, which is the optimal development temperature. The characteristic of pupae is that they are relatively cold-resistant. According to experiments, housefly pupae were refrigerated in a refrigerator at a temperature of 1°C and an ambient humidity of 85% for 4 days and then returned to normal room temperature. The emergence period was only delayed by 1 day compared to the normal pupal period; refrigeration for 3 days in the above environment did not reduce its emergence rate.

② Humidity: According to experiments, the best culture medium humidity for pupae development is 45% to 55%. Higher than 70% or lower than 15% will significantly affect the normal emergence of pupae. If pupae are soaked in water, the longer the time, the lower the pupation rate of fly maggots and the emergence rate of pupae. Someone once fished out 1,000 fly pupae from liquid garbage, and after transferring them to a dry environment, not a single one of them emerged as an adult fly.

If the nutrients for larvae are insufficient, the larvae will pupate without fully developing. Such pupae can also hatch into adult flies, but more than 95% of these adult flies are males, which only eat food and do not lay eggs. They will all die in about a week. Therefore, the larvae used for seed pupation must be raised with sufficient nutrients to make them fatter. The larger the proportion of females, the more females there are. Only when there are more female seed flies can the egg-laying capacity be guaranteed and the yield be stable.

2. Where do the maggots come from? How do the little flies reproduce?

My goodness, this question is very strange! Let me, a farmer, answer it for you. Feel free to give me points, don't be afraid of being disgusted!

Maggots are the pupae of flies. After mating, flies lay their pupae in feces, rotten food, or dead animals, etc. Then their eggs grow into maggots. When the maggots grow to a certain size, they will harden and shed their shells, and then they will become flies... This cycle continues! I can't stand it anymore, buddy, is it easy to earn points? Get the points quickly...

3. Will the maggots die after being eaten? Or will they reproduce?

If it enters the stomach, it will die, of course, because stomach acid is very corrosive, and because your body is metabolizing normally, it is impossible for it to reproduce! Don't worry!

4. Some people have proposed that “life (maggots) can occur naturally, rather than evolving” based on the fact that maggots grow in rotting meat.

The rotten meat is not disinfected, but stored in a sterile environment. A control group is set up and stored in a natural environment. The experimental group will not have maggots, while the control group will have
