Miami Launches ZAP Males® Mosquitoes to Fight Zika

ZAP Males® become a ‘biopesticide' to stop the Zika virus from spreading

Thousands of bacteria-infected mosquitoes will soon be flying near Miami, Florida to hopefully reduce the mosquitoes that carry the Zika virus.

A statement released on the Miami-Dade County website, says this Zika prevention program will designate 2 small areas near Miami, Florida, for testing a new science.

Surveys of the Aedes populations will be taken before and then again after each weekly or twice-weekly treatments.

This new science is turning these flying pests into ZAP Males®.

Once male mosquitoes are infected with the ZAP strain, a particular strain of the Wolbachia bacterium, and then mate with females, they produce offspring that do not survive.

ZAP Males® reduce local populations of the type of mosquito (Aedes albopictus, or Asian Tiger Mosquitoes) that can spread numerous diseases of significant human health concern, including the Zika virus, says MosquitoMate.

These modified mosquitoes become a ‘biopesticide' to stop the Zika virus from spreading further.

Biopesticides include naturally occurring substances that control pests (biochemical pesticides), microorganisms that control pests (microbial pesticides), and pesticidal substances produced by plants containing added genetic material (plant-incorporated protectants) or PIPs.

According to a statement from the Kentucky-based company, MosquitoMate, the first mosquitoes were released in Florida near Key West during June 2017. That test was in collaboration with the Miami-Dade County Mosquito Control and Habitat Management Division.

MosquitoMate has completed successful trials in Kentucky, California, and New York. Trials have shown a significant reduction in the female Aedes aegypti mosquito population.

MosquitoMate infects male Aedes aegypti mosquitoes with the naturally occurring Wolbachia bacteria. Any offspring produced when the lab-bred mosquitoes mate with wild female mosquitoes won't survive to adulthood.

According to Dr. Stephen Dobson with MosquitoMate, Inc., “Male mosquitoes do not bite, and Wolbachia is not harmful to humans.”

The Key West test “ended a bit early due to Hurricane Irma,” Dr. Dobson told Lex18 News.

The results from the Key West test are still pending.

MosquitoMate, Inc., a Lexington, Kentucky based company, is a privately-held biotechnology company, founded on Intellectual Property developed at the University of Kentucky, Department of Entomology.
