A half-dozen non-native Aedes aegypti mosquitoes have been detected in East San Jose, according to the county. The insect is invasive and has been known to spread diseases such as dengue, Zika and yellow fever. 

The oriental fruit fly, which comes from Asia and has recently spread to Pacific Islands, is considered a "significant threat" to both the natural ecosystem and the state's multibillion-dollar agriculture industry.

To prevent the spread of Oriental Fruit Flies through homegrown fruits and vegetables, residents living in the quarantine area in Santa Clara County are urged not to move those items from their property.
