CATDOLL : CATDOLL: Do flies lay live young or lay eggs?

1. Are flies viviparous or oviparous?

Everyone is familiar with flies. Every year in the hot summer, there will be a lot of flies, and they reproduce very quickly. As long as the temperature is right, they will reproduce a lot of flies, which brings a lot of trouble to people. So are flies viviparous or oviparous? Oviparous, from a professional point of view, flies have an egg stage in their development. At the same time, in the long-term evolution process, different types of flies will evolve different egg hatching mechanisms. After most flies lay eggs, it takes about 1 to 2 days for the temperature to be between 20% and 30%, and the humidity to be controlled between 60% and 80% to hatch. However, some flies, after their eggs are swallowed by parasites, will rely on the action of gastric juice to hatch.

2. What should I do if the hamster’s nest becomes a breeding ground for flies?

The reason why flies breed in hamster nests first depends on the breeding conditions of flies. "Reproduction is closely related to the ambient temperature: an average of 9 days at 15°C, only 1.8 days at 35°C, and eggs cannot be laid below 15°C. After mating, female flies often crawl into breeding crevices such as human and animal feces, extend their ovipositors and lay eggs deep in the breeding organisms to ensure that the eggs are fully protected." It can be inferred that the poor sanitary environment of the hamster nest has created conditions for the reproduction of flies. I hope you clean and disinfect the hamster nest.

The best way is to wash it clean! It is best to use sterilization, insect repellent hand soap or dishwashing liquid.

3. All the flies die in winter, so how do they reproduce in summer?

In winter, they just leave their eggs in a hidden place. When the temperature rises in summer, they start to reproduce.

4. How can we make flies lay more eggs?

A housefly lays eggs about 3 times in its lifetime, but can lay 4-6 times, with 100-200 eggs each time! Houseflies can reproduce 10-12 generations in a year.

5. Do flies reproduce by eggs?

Yes, flies reproduce by eggs.

6. What kind of bacteria and in what environment can flies reproduce?

Flies do not reproduce from bacteria, they lay eggs.

Flies have the physiological characteristic of laying eggs for life after mating once. A female fly can lay eggs 5-6 times in her lifetime, with about 100-150 eggs laid each time, and up to 300 eggs at most. It can reproduce 10-12 generations in a year.

Under suitable temperature, male houseflies can reach sexual maturity and mate 18 to 24 hours after emergence and female houseflies can reach sexual maturity and mate 30 hours after emergence. Mating usually takes place between 5:00 and 7:00 in the morning. Sensitive sense of smell, sex pheromones and vision are all important factors that promote mating between male and female flies. A mating pair of houseflies can stay in one place for a long time, crawling together, flying together, and the effective mating time can be up to 1 hour. Most houseflies only mate once in their lifetime. The semen of male flies can be stored in the spermathecae of female flies for a long time, stimulating egg laying, and the eggs can be continuously fertilized for 2 to 3 weeks without mating with another male fly. This is rare in other insects. This is the important reason why flies have strong fertility.

The peak period of egg-laying is from 17:00 to 19:00 every day. The length of the pre-oviposition period of female flies (i.e. the time from emergence to the first egg-laying) is closely related to the ambient temperature: an average of 9 days at 15°C, only 1.8 days at 35°C, and no eggs can be laid at temperatures below 15°C. After mating, female flies often crawl into breeding crevices such as human and animal feces, extend their ovipositors and lay eggs deep in the breeding organisms to ensure that the eggs are fully protected.

??Flies have amazing fertility. It has been observed that houseflies in the laboratory lay about 100 eggs per batch, and one female fly can lay 10-20 batches of eggs, with a total of 600-1000 eggs. In nature, each female fly can lay 4-6 batches of eggs in its lifetime, with an interval of 3-4 days between each batch, and each batch of about 100 eggs, with a lifetime egg production of 400-600 eggs. Even in North China, houseflies can reproduce 10-12 generations a year. According to the most conservative estimate, each female fly can produce 200 offspring, so 100 female flies only need 10 generations to reproduce a total of 200 trillion flies!
