Can We Make Mosquitoes Extinct?
Attempts to make mosquitoes extinct have been underway for a long time. The most effective techniques are local extirpations and targeted insecticides. While these methods seem promising, they are also quite expensive.
Aedes aegypti and Culex quinquefasciatus are the main species carrying the Zika virus. There are other species that feed on humans and other animals. Some human-feeding species carry malaria and other human diseases pathogens. When the population of mosquitoes falls below a certain threshold, they may die out naturally. But this is unlikely.
One scientist who has studied malaria-carrying mosquitoes for 20 years believes that it would be better to wipe them out rather than try to control them. He says that a large number of sterile males are needed to have any effect.
But if the mosquitoes were gone, plants and fish would suffer. Some animals, like woodland caribou, would be forced to find other prey. Others, like dodo birds, would be destroyed. But most animals would adapt to the new situation.
The problem with eradicating a single species is that it is difficult to predict what will happen to the rest of the ecosystem. In fact, tampering with an ecosystem has been shown to be harmful in many cases. This is because it has been shown to disrupt the balance of species.
But if you’re trying to control mosquitoes on a global scale, the problems become even more complex. Not only are there many insecticides that are nontoxic to humans, but they have unknown effects on other species.
