Suppose mosquito species disappear in the world, and the insects that eat mosquitoes or some animals like spiders, salamanders, lizards and frogs are affected. Just because mosquitoes disappear from their diet doesn't mean they have to be mosquitoes. A large number of birds that prey on mosquitoes are likely to turn to other insects, which will multiply in large numbers in the "post-mosquito era" to replace the mosquito niche. Other animals and plants that feed on insects may not think of them at all. Bats mainly prey on moths, and mosquitoes account for less than 2% in their stomachs. There are many choices on the menu. It seems that in a world without mosquitoes, most insect predators will not starve to death.

Phil, an ecologist from Florida Medical Entomology Laboratory? Phil Lounibos believes that "eliminating mosquitoes will only temporarily alleviate human suffering". His research shows that efforts to eliminate the species carried by pathogenic microorganisms will be futile, because this niche gap will soon be filled by other organisms. His team collected female yellow fever mosquitoes (Aedes aegypti) from garbage dumps in Florida and found that some of them had been fertilized by Asian tiger mosquitoes (Aedes albopictus), which carried many human diseases. This fertilization process will make female yellow fever mosquitoes lose their fertility, which shows how one species replaces another.

In view of the serious humanitarian and economic consequences caused by mosquito-borne diseases, most scientists will think that the improvement of overall human health will exceed the cost of population growth. The idea that it will cause "collateral damage" to the ecosystem will not win the sympathy of mosquitoes. The romantic view that "every living thing in nature plays an important role" is not enough to justify the mosquito test. There are mosquitoes in the world, not because humans deliberately let them run rampant, but because their ability is limited.
