State College buzzes over seeming onslaught of flies
Remember the much-discussed stench that swept parts of the Centre Region early this month, just about the time that Penn State spread some powerful manure on nearby farm fields?
Consider this Chapter Two.
In the past two weeks or so, since the stink dissipated, locals have said houseflies are appearing at startling rates -- indoors, at picnics, everywhere. Steve Jacobs, a Penn State extension associate who specializes in entomology, confirmed the reports Wednesday and said that, at least in his anecdotal observations, the housefly population in and around State College seems unusually abundant.
...in downtown State College, the buzz centered largely on the university's manure-spreading operation earlier in the month. Rebecca Durst, owner of Rinaldo's Barber Shop on South Allen Street, said the excrement seemed the likely culprit.
"The flies are driving us crazy," Durst said as another barber swatted toward a mirror. "They're interrupting our cutting. They've been a nuisance to us and our customers."
Susan Jones, an associate professor of entomology at Ohio State University, said she "would have expected to see a (fly) boom right after" the manure-spreading. Penn State farm workers labored at least four days during the week of Aug. 1 to apply potent livestock dung to fields near Aaron Drive, in an area relatively near the northern edge of the University Park campus and East College Heights.
Jones said such manure is a favorite breeding source for house flies. Adult house flies can live 14 to 70 days, depending on whose studies you believe, she said.
"If (the manure) was moist, then it would be a ready place for them to breed," Jones said.
