American environmentalists are using drones to reduce the mosquito population. AP reports.
The life cycle of mosquitoes is inextricably linked with stagnant and calm bodies of water, especially swamps. Blood-drinking females lay eggs inside them, which develop into floating larvae. At this stage of development, the larvae are concentrated and therefore vulnerable.
An unusually wet winter has plagued California with mosquitoes this year. Traps catch 15 times more of these insects than the average. In this context, environmentalists have begun using drones to spray bacterial spores that kill larvae. Common mosquito control methods include backpacking sprayers, cars, airplanes and helicopters. According to experts, the drone allows you to more accurately treat the area without the need to crush the soil with a fragile ecosystem and disturb the inhabitants.
According to environmentalist Keith Nguyen, the drone flies higher than any bird nesting in the swamp, allowing you to reach places beyond the reach of a person with a backpack sprayer. The drone can process 1 acre (0.4 hectares) of land in less than two minutes; this is a task that would take over an hour for a worker with a backpack to complete. Experts say that this method of processing usually does not bother even herons.
Mosquito larvae are filter feeders and feed on microorganisms. For this reason, the sprayed special bacteria penetrate their intestines and begin to multiply by tearing from the inside.
