Researchers developed a new gel-based trap that combines a natural fungus (Beauveria bassiana) with specially designed hydrogels to control Asian tiger mosquitoes (Aedes albopictus), which spread dangerous diseases like Zika and dengue. The gel traps work by both mechanically trapping mosquito eggs and infecting them with the fungus, achieving over 90% effectiveness. This approach offers a chemical-free alternative to traditional insecticides and could be more cost-effective than current methods.
