A tiny little mosquito normally found halfway around the world has turned up in Ventura County for the first time. 

It has health officials worried, because it has the ability to transmit tropical viruses normally not found here.

Mosquitoes are an annoyance at best, and a danger at worst on the Central and South Coasts because of West Nile virus and Zika virus concerns.

Some U-C Santa Barbara researchers are part of an effort at six UC campuses to try to develop safer, and more effective ways that pesticides to control the insects.
