Asian tiger mosquito detected in california this summer 2013

The asian tiger mosquito is present in California. It was first detected in the Central Valley communities of Madera and Clovis in June, and were detected again this week in the city of Fresno and in Menlo Park in August.

This mosquito bytes during the day, and can transmit several deseases like dengue or chikungunya, or the yellow fever. These deseases can kill. For now, the 200 cases of dengue detected since 2010 were imported cases (desease contracted in another country). But is one asian tiger mosquito bytes an infected person, it can carry and transmit the desease. Imagine if it occurs in California. “The nightmare scenarios is it gets established in California and then a mosquito bites someone with an imported case of dengue,” Phillips said.
The asian tiger mosquito is also present in Arizona and Texas.

“If it gets away it will change the way we live in California. You may not be able to sit on your patio and enjoy a cup of coffee during the day without getting bit,” said Tim Phillips of the Fresno Mosquito and Vector Control District.

In the places where this mosquito has established, you have to change the way you live.

Wolbachia bacterium to slow spread of asian tiger mosquitoes

The Asian tiger mosquitoe has arrived a few years ago to the United States, and they’re now spreading.
The female asian tiger mosquitoe needs blood to support egg-bearing (males do no byte).
A University of Kentucky found that asian tiger mosquitoes were responsible for 90 to 95 % of bites on Lexington test subjects during summer 2013.
Scientists are thus working on a method to stop the spread of these mosquitoes, which are now in every Kentucky county and are flying west — toward California — and north — toward New York and New Jersey. This technology is developed at UK, but licensed to the Kentucky company MosquitoMate.

The idea is to use the bacterium Wolbachia. Releasing males with a different strain of this bacterium from that in the females in a targeted area results in males mating with females and producing nothing. The eggs don’t develop.
The release of the Wolbachia-bearing male mosquitoes puts a substantial dent in the biting Asian mosquito population. A mosquito tends to stay in a fairly small area during its life, usually less than 150-200 meters.

In 2014, the UK researchers will begin studies with the new-strain Wolbachia mosquitoes in neighborhoods around the university.
