“If we launch a adequate variety of sterile males throughout a sure interval in an space, the mosquito inhabitants in that space will lower,” Ana Klobucar, a medical entomologist of the Zagreb-based instructing institute of public well being who’s overseeing the mission, advised AFP.

The plan is rooted within the Sterile Insect Method (SIT)—a way that has been used for many years internationally to fight varied dangerous bugs, however remains to be being examined for its effectiveness in opposition to mosquitoes in city areas.

Croatia began utilizing it for mosquitoes final 12 months in northern Istria peninsula.

This 12 months a complete of 1.2 million specifically handled bugs will likely be launched there over a three-month interval, entomologist Nediljko Landeka of the regional public well being institute advised AFP.

The bugs—which have been rendered sterile after publicity to gamma rays— are sourced from a laboratory in Italy, and shipped 500 kilometers (310 miles) to Croatia in particular bins.

As soon as acquired, Klobucar and her assistants fastidiously take away plastic bowls with the bugs from cardboard tubes earlier than they’re later dispersed in native gardens within the goal space.

Because the mercury rises throughout the globe, the Asian Tiger mosquito is transferring additional north together with in areas that had been thought of too chilly for the species to thrive, together with in Switzerland and Germany.

“We’re afraid that along with the species, viruses might additionally simply adapt sooner or later to new environments,” warned Greek entomologist Antonios Michaelakis.

The breed has now unfold to greater than a dozen European nations, with the Mediterranean area having been hit the toughest, in line with official figures.

Michaelakis—who can also be a researcher on the Benaki Phytopathological Institute in Athens— has been instrumental in sharing his experiences from a program in Greece along with his Croatian counterparts.

In Greece in 2019, the mission succeeded in slashing the inhabitants of Asian Tiger mosquitoes by 90 %, he advised AFP.

Throughout a trial of the method final 12 months in Croatia’s Istria, as much as 14 % of mosquito eggs within the space had been discovered to be sterile and jumped to almost 60 % this 12 months, Landeka added.
