China has implemented an innovative biological strategy to combat the chikungunya outbreak in the Guangdong province. With over 7,000 reported cases, authorities have released Toxorhynchites mosquitoes, known as "hunter mosquitoes," whose larvae feed on those of Aedes aegypti, the main vector of the virus. Additionally, in the city of Foshan, more than 5,000 predatory fish have been released that consume mosquito larvae in local ponds and rivers.

These measures are part of an ecological approach to reduce the mosquito population without resorting to the massive use of insecticides, seeking a more sustainable and less harmful solution for the environment and human health.
