What is the 'Toxic Male Technique' to control mosquito population?

To control mosquito population, Australian scientists have tested the "Toxic Male Technique" in a species of mosquito that spreads dengue fever, Zika and other viruses. Scientists said toxic male mosquitoes will poison females with their semen. The method involves genetically engineering males to produce spider and sea anemone venom proteins, which they inject into females during mating.
