Researchers from Macquarie University in Australia have developed 'Toxic Male' mosquitoes to combat disease-carrying female mosquitoes. These engineered males transmit a venom to females during mating, effectively acting as natural pesticides. This method aims to reduce mosquito populations without harming beneficial species. The study highlights the effectiveness of targeting female mosquitoes, known for spreading deadly diseases like dengue and malaria. This innovative approach could provide a solution to pesticide resistance and enhance biocontrol strategies globally.
