CATDOLL : CATDOLL: Why are flies so difficult to eradicate?

Why are flies so difficult to eradicate?

Flies first appeared in the Cretaceous period, about 145 million years ago. The direct evidence is that scientists found amber with flies in a mine in Myanmar, and the formation time of this amber became the earliest time when flies appeared. Although the life span of flies is only about 1 month, they have strong reproductive capacity. The diet of flies is very complex. They are omnivorous flies and can feed on various substances. After the housefly is full, it can defecate in a short interval (a few minutes). Flies can spread 50 diseases.

Reasons why flies are difficult to eradicate:

1. Flies have amazing reproductive capacity.

Flies can reproduce 10 to 12 generations a year. According to the most conservative estimate, each female fly can produce 200 offspring. So, 100 female flies will only need 10 generations to reproduce a total of 200 trillion flies!

2. Strong ability to adapt to the environment.

Where you can adapt, flies can definitely adapt. Where you cannot adapt, flies can also adapt. But where flies can live, you may not be able to live.

3. Flies are very important in the food chain of the ecosystem.

It is the staple food of many creatures. If flies become extinct, many creatures will become extinct. At the same time, if mosquitoes become extinct, the bodies of dead animals will decompose more slowly, thus affecting grasslands, water sources, animal distribution, and spreading diseases, leading to species extinction, which directly affects human survival. Haven't you heard about the news that Australia imported dung beetles? Flies cannot be exterminated just because you want to!
