Asian tiger mosquitoes discovered in Windsor (Canada) trap

Two adult aedes albopictus mosquitoes were found in a single local surveillance trap, said Health officials on the lookout for the presence of mosquitoes capable of transmitting the Zika and West Nile viruses.

This kind of mosquito, also known as the Asian tiger mosquito, can transmit viruses including Zika, Chikungunya or west nile virus.

A lab analysis determined these two mosquitoes were not carrying West Nile or Zika nore chikungunya.

During the surveillance program last year, 17 Asian tiger mosquitoes were trapped locally and none had Zika or West Nile. In the fall, the health unit reported it had also discovered aedes aegypti larvae. This species of mosquito, also known as the yellow fever mosquito, is responsible for most of the Zika cases in the Caribbean, South America and Florida. The mosquitoes that officials reared from the aedes aegypti larvae all tested negative for Zika.

The Asian tiger mosquitoes have been found across the U.S., including in areas with climates similar to here, like Vermont, New York, New Hampshire and Massachusetts.

The two found this summer may be from a new colony — perhaps transported from the U.S. in shipping containers or cross-border trucks — or they may have originated from last year’s colony, which may have survived the winter because of the mild weather.

“The discovery of the Asian tiger mosquitoes again this year is an important reminder to everyone that we should continue to protect ourselves and our families from mosquito bites,” acting medical officer of health Dr. Ahmed said in the news release.

Until freezing temperatures arrive, it’s important to take precautions against mosquito bites, the health unit says. These include: using insect repellents containing DEET, Icaridin or other approved ingredients; wearing long pants, long-sleeved shirts and hats when outdoors; and making sure window screens and doors don’t have any holes or other openings that allow mosquitoes to get indoors.
