Genetically engineered mosquitoes with toxic semen could be a new weapon against tropical disease, Australian scientists said after trialling the novel pest control method. Genetic engineering has been used for years to control populations of disease-spreading mosquitoes.

Genetically engineered mosquitoes with toxic semen could be a new weapon against tropical disease, Australian scientists said after trialling the novel pest control method.

Genetically modified mosquitoes could be the solution to stopping deadly diseases spread by mozzie bites, scientists say.

The ‘toxic male technique’ aims to breed male mosquitoes that kill disease-spreading females through the act of mating.
