Asian Tiger Mosquito Invades Allegheny County (Jul 28, 2010)
Allegheny County Health Department.
The Allegheny County Health Department reported that on Jul 26, several samples of the Asian tiger mosquito (Aedes albopictus) were collected from an area in West Mifflin. While the Asian tiger mosquito has been sporadically trapped in the County for several years, this is the first time it has infested an entire neighborhood. Efforts are planned to control the source of the problem in West Mifflin. In addition, mosquitoes collected last week from Pittsburgh's West End and North Side have tested positive for the West Nile virus.

Emerald Ash Borer Survey Program
Pennsylvania Department of Agriculture.
The emerald ash borer was first detected in Pennsylvania in the summer of 2007. One of the easiest ways for exotic invasive pests like Asian Longhorned Beetle, Emerald Ash Borer, Sirex Wood Wasp and Bark Beetles to spread is by people unintentionally moving infested products. To minimize the spread of the pests, the Pennsylvania Department of Agriculture has implemented a quarantine banning the importation of out-of-state firewood. People who suspect they have seen Emerald Ash Borer should call the department's toll-free pest hotline at 1-866-253-7189.
