In Montpellier, a revolutionary “factory” breeds and sterilizes millions of mosquitoes to control their invasion

In an effort to reduce populations of intrusive and harmful mosquitoes, a unique company in mainland France has emerged: Terratis, based in Montpellier. This innovative company has discovered a technique for the mass production ofsterile male mosquitoes, aiming to control the proliferation of these invasive and disease-carrying insects. This promising method, which involves the release of millions of sterile mosquitoes, is proving to be a significant advance in the fight against these flying pests. State-of-the-art laboratoriesLocated in an unassuming 220-square-meter warehouse west of Montpellier,

Terratis

leverages science and innovation to cultivate approximately one million mosquitoes at a time. The interiors of this laboratory are impressive, with dozens of ultra-fine mesh cages housing these insects. This is no ordinary spectacle, but a necessity in the battle against mosquito overpopulation, particularly the dreaded Aedes albopictus, or tiger mosquito. The Method and Process The process developed by Terratis involves sterilizing male mosquitoes using precise irradiation. Once these sterile males are released into the wild, they mate with wild females. However, due to their defective sperm, the embryos are not viable, preventing the hatching of new generations of mosquitoes. This process, when properly orchestrated, has the potential to drastically reduce mosquito populations in the long term.Health and Environmental Stakes

Mosquitoes are not just a nuisance; they also pose a threat to public health.

mosquitoes are vectors of serious diseases such as dengue and chikungunya. By reducing their numbers, Terratis actively contributes to decreasing the risk of these diseases spreading. The company’s approach has gained supporters, who see it as an ecologicaland non-polluting solution to the widespread use of chemical pesticides. Impact and future prospectsThis mosquito control initiative in Montpellier paves the way for

considerable progress

in managing nuisance populations worldwide. The commitment of Clelia Oliva, president and co-founder of Terratis , lies in extending these methods to other regions affected by these insects. The success in Montpellier could serve as a model for combining technology and ecology to benefit human health.
