Do flies reproduce sexually or asexually

Egg larvae (maggots) pupal process of adult fliesThe fly production process takes only about 1 day, and it can be shortened when the temperature is high. After 10 days, these 1 eggs become adult flies, so a fly can reproduce thousands of flies in its lifetime.

The lifespan of flies is not long, under normal circumstances, flies can survive for 1 month in summer, and if the temperature is low, the survival time will be extended by 2-3 months.

Although the life is short, it reproduces quickly, and it only needs to mate once in a lifetime to produce eggs for life, and the number of eggs laid at one time can reach up to about 3.

FliesMale and female mating is required to reproduce offspring. However, the mating of flies only takes one time, after which the female flies are able to lay eggs for life, which is very different from other animals. Generally speaking, the peak breeding period of flies should be from June to October every year, when the temperature is relatively high, and the reproductive ability of flies is also particularly strong, a female fly can lay 100 to 150 eggs at a time, and the female fly can lay eggs 5 to 6 times in her life, so the number of eggs laid by a fly is considerable.

Reproductive ability of flies:Flies have amazing fecundity. 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 in her lifetime, with a total of 600 1000 eggs.

In nature, each female fly can lay 4 6 batches of eggs in her lifetime, with an interval of 3 4 days between each batch, and each batch lays about 100 eggs, and the lifetime egg production is 400 600 eggs. Houseflies can reproduce 10 to 12 generations a year, and according to the most conservative estimates, each female fly can produce 200 offspring, so 100 female flies only need to go through 10 generations, and the total number of flies that reproduce will reach 2 trillion billion.

The reproduction mode of flies is mainly oviparous, after the mating of male flies and female flies, female flies will lay eggs, and the peak breeding period of flies is generally from June to October every year, and each female fly can lay 100 to 150 eggs.

Fly breeding methods:

The peak of spawning is at 17:00 to 19:00 every day.

The length of the pre-oviposition period (i.e. the time from emergence, to the first oviposition) of female flies is closely related to the ambient temperature: an average of 9 days at 15 oviposition, only a few days at 35 ovitable, and no eggs can be laid at 15 years or less. After mating, female flies often crawl into breeding crevices such as human and animal feces, and extend out of the ovipositor tube to lay eggs deep in the breeding organism, so that the eggs can be fully protected.
