A new study brings bad news for people fighting bedbug infestations and companies that sell over-the-counter insecticides. Ohio State University entomologists Susan Jones and Joshua Bryant found that “bug bombs” and “foggers” — cheap, insecticide-spraying aerosols that have been marketed for decades as do-it-yourself alternatives to exterminators — were ineffective against even the most vulnerable of bedbugs.
PA IPM's Ed Rajotte shares a chuckle with S. Mohankumar at a symposium on "Research and Management of Insect-Transmitted Virus Diseases" at Tamil Nadu Agricultural University on the first day of the 4-day meeting. The gathering is bringing together scientists from developing countries around the world to look at ways to address the challenges that virus diseases present for global food security.
One of the toughest parts of growing grapes is getting the climate right. An early frost, the crop could be damaged. Too much rain, the grape sugars are diluted.
Beginner and experienced beekeepers and those thinking about taking up backyard beekeeping can get the information they need to be successful from Beekeeping 101, a new online beekeeping course offered by Penn State Extension.

A mosquito sample from Potter Township has tested positive for the West Nile virus. It is the fourth positive mosquito sample found so far this year in Centre County. The others were found in Snow Shoe Township and Benner Township in May and Gregg Township on June 20.
Mosquito samples collected by Penn State Extension staff on June 20 in New Salem and June 21 in Dover Township have tested positive for West Nile virus by the Pennsylvania Department of Environmental Protection.

With all the rain we have been experiencing, there is the distinct possibility that you could see late blight on your tomatoes and potatoes. There has been late blight already reported and confirmed in Pennsylvania on tomatoes and potatoes.
What's bugging entomologists as summer begins? Stink bugs, but not in the way you would think. Tim Nagy, 45, of South Fayette, was "dive-bombed" by stink bugs all over his home last year -- so bad that his dog began eating them for fun. This year, however, he has hardly seen any.
Remember the luxury of not having to shovel snow this past winter? And being able to don shorts in 79–degree warmth in March? Well the chickens might be coming home to roost. A pair of weather–related pests — armyworms and late–blight disease — have broken out in Lancaster County threatening this year's yield of tomatoes sweet corn and other crops grown by both farmers and backyard gardeners.
After likely staying alive through a mild winter and spring, late blight - the plant disease that caused the deadly Irish potato famine - has been found in area farms for a fourth consecutive summer. "We're finding it in more counties every day," said Beth Gugino, assistant professor of plant pathology at Penn State University. "We're trying to get the word out that it's around."
Plant diseases caused by insect-transmitted viruses are a threat to the food security of developing countries, causing serious crop and income losses for people whose livelihoods depend on farming. A symposium in India sponsored by an Indian university and the American government and co-organized by Penn State will bring together scientists to review the status of these diseases and discuss methods of combating them.
Dairy farmer Terry Wilson said his corn, hay and oat crops were coming up like they should until a week ago when he noticed one field full of young corn that looked like it was only half there. Closer examination revealed it had been eaten down to the ground by pseudaleta unipuncta, or armyworms.
Cockroaches are not just insidious home invaders, a new study finds; they are also brilliant escape artists. A roach can flip under a ledge by swinging its body around like a pendulum and hanging on underneath. It uses hook-like claws to hold on firmly.
We continue to hear about the armyworm outbreak across Pennsylvania, up into New York, and over into Ohio. This has been a widespread, destructive, and generally impressive situation. It reminds me that as much as we would like to have control over nature, occasionally it can produce situations that are beyond our control.
An iconic hotel in the heart of midtown Manhattan is buzzing with thousands of tiny new visitors. But watch out: They'll sting if you get too close.
Let DCNR's David Schmit take you on a tour of some of Pennsylvania forests' nastiest invasive pests...and learn how to avoid spreading more of them around the state.
Late blight, the same disease that caused Ireland's potato famine in the 19th century, was confirmed in three Pennsylvania counties this past week.
Colony Collapse Disorder has become primetime news as a cause for poor honeybee health in the US and around the world. Maryann Frazier, Honeybee Extension Associate, Penn State has so simple steps that homeowners can do to help our pollinating partners.
They’re back…. Extension offices and lawn care companies across Pennsylvania have received numerous calls over the last few weeks about a plague of worms.
