Did this event really happen or was it an April Fool's joke? I looked online and could find no other sites to corroborate the story. Nonetheless, it is an interesting one. It reminds me of Orson Welles' War of the Worlds broadcast on the radio back in the 1930's. Sometimes, our immediate reaction to a perceived threat is to panic, rather than to question if the threat is really genuine. If scientists reacted to the mosquito like that, what would uneducated individuals do?
