As the recent Miami outbreak of Zika virus, transmitted by the bite of female "Aedes aegypti "mosquitoes, prompts an all-out war on the pest, new research reveals that female mosquitoes can pass the virus on to their eggs and offspring, bolstering the need for larvicide use as an integral part of the effort to stop the spread of the virus.
"The implications for viral control are clear," said study co-author Robert Tesh, MD, at the University of Texas Medical Branch in Galveston, Texas. "It makes control harder. Spraying affects adults, but it does not usually kill the immature forms -- the eggs and larvae. Spraying will reduce transmission, but it may not eliminate the virus."
The study, "Vertical transmission of Zika virus in "Aedes aegypti "mosquitoes," was published online today in the "American Journal of Tropical Medicine and Hygiene.
"Since Zika virus has emerged as a global health emergency, most research has focused on the virus and its effects on humans. There is far less research on the virus in its mosquito host," said Tesh. "But if you want to control Zika, you also have to know about the behavior of this virus in mosquitoes."
