There has been plenty of publicity about Panama's latest undesirable import from the Far East, the Aedes albopictus, or Asian Tiger Mosquito, shown above. Like our better established pest, Aedes egypti, this one will transmit dengue fever and if it finds the right living reservoir to bite it can be a yellow fever vector as well. The newcomer has a bigger range and can carry West Nile fever as well.

But don't panic. This day-biting insect species breeds in the same ways and places that Aedes egypti does --- in containers rather than swamps or other large natural bodies of water, more often in trash-strewn urban areas that in the remote rural boonies. See the wigglers, and the sorts of places they grow, in the photos below. You prevent the diseases that this unwelcome newcomer spreads by cleaning up the trash, emptying containers that hold water and not creating tiny bodies of water that attract these pests.
