By adding life-shortening bacteria to disease-carrying mosquitoes, Australian researchers might have found a clever way to control Dengue fever, a developing world scourge now becoming common in the southern United States.

What if all mosquitoes died?

If mosquitoes were eradicated from the planet, hundreds of species of fish would have to change their diet. ... Without these fish, the food chain would be disrupted in both directions. Some species of bird, bat, spider, insect, salamander, lizard, and frog also eat mosquitoes, and may struggle without them.

What if mosquitoes went extinct?

If mosquitoes were eliminated, the number of birds in the area could drop by more than half [source: Fang]. ... In fact, if mosquitoes were to disappear, the other insects and fish that feed on them would dwindle in number, which could cause a ripple effect throughout the food chain [source: Misra].
