All individuals will get the parasite. That's the key to this whole strategy.". The Dengue virus itself could also evolve into a more rapidly-maturing form, but O'Neill thinks this unlikely. Only a few mosquitoes now live long enough for Dengue to reach full virulence: selection already favors accelerated development.

Its use, he said, "should have no deleterious effects on the ecology.". Gubler called the potential Dengue benefits "immeasurable" — and that, said O'Neill, could be just the beginning. "The underlying principle applies to a range of other pathogens, including elephantiasis and malaria," he said.

The World Health Organization, he added, reports that more than 50 percent of the world’s population is presently at risk from mosquito-borne diseases. Zika and other insect-borne diseases are traveling quickly with new reports every week.
Why do mosquitoes feed?
Feeding allows the mosquito to produce eggs. When feeding, a mosquito pierces the skin like a needle and injects saliva into a person’s skin. This allows the disease-causing agent – for example, the Zika virus – into the site.”. Only a small fraction of fly species, however, will bite people, Peterson said.
Why are mosquitoes effective transmitters?
The virus is spreading rapidly because mosquitoes are more effective transmitters of disease than even flies. “Mosquitoes spread disease-causing agents, not the disease,” Peterson said.

All towns and cities should maintain a web page that provides mosquito information and relevant pesticide laws to residents. Towns can also enact ordinances on third-party pesticide applications. For example, a town might require that franchises alert neighbors 48 hours before spraying is done.
Can pyrethroids kill fish?
It is increasingly accepted that runoff of pyrethroids into creeks can kill fish downstream. Finally, pyrethroids are toxic to certain earthworms. This is probably especially true for those species that come out onto lawn surfaces in the evening, when pyrethroids are often applied.
