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.

If there's one thing worse than finding a tick, it's wondering whether that tick has passed on Lyme disease. Pennsylvania continues to be one of the leading states for Lyme disease, with between 3,000 to 4,000 new cases every year, according to the State Department of Health.
Insect damage recently found on some area ash trees wasn't caused by the emerald ash borer, an invasive insect that's destroyed tens of millions of trees since its discovery a decade ago in Michigan.
Consumer products known as "bug bombs" or "foggers" have been sold for decades for use against many common household insects. However, recent research published in the Journal of Economic Entomology (JEE) shows these products to be ineffective against bed bugs.
A popular publication in the mushroom industry that addresses pests with the most potential to reduce mushroom yield and quality is now available in Spanish for free online.
