Among the after-effects of Tropical Storm Cristóbal is the arrival of Aedes taeniorhynchus, popularly known as “mosco negro.”

Increasing numbers of black salt marsh mosquitoes have been reported swarming in the east and west of Merida, as well as in parks.

Culex quiquefasciatus, or southern house mosquito, has also made a resurgence.

The Yucatan Health Ministry acknowledged the problem, promising to deploy insecticide foggers to combat the problem. A date to start the operation was not specified.

Aedes taeniorhynchus, whose sting is painful, is typical of Yucatan’s wetlands and mangroves but rain has increased their numbers while strong winds have blown them into the city.

The devious mosquito species rests in vegetation during the day and attack any mammal or bird that invades their spaces, even in full sun.
