Mosquitoes infected with the bacteria Wolbachia are more likely to become infected with West Nile virus and more likely to transmit the virus to humans, according to a team of researchers.
Flor’s poster, titled “Plasticity of secreted saliva in a polyphagous lepidopteran insect and its effect on plant defense responses,” received the ISCE Student Presentation Award for best poster at the 2014 International Society of Chemical Ecology Meeting in Champagne-Urbana, Illinois.
Frazier, a Penn State senior extension associate with the university’s Center for Pollinator Research, is part of a team of scientists studying the effects of pesticides on honeybee colonies.
This is the 4th of twelve short news articles written by students, during the professional development class, about each other's research.
Malaria parasites alter the chemical odor signal of their hosts to attract mosquitos and better spread their offspring, according to researchers, who believe this scent change could be used as a diagnostic tool.
Penn State announced today (July 2) that Richard Roush will be the new dean of the College of Agricultural Sciences, pending approval by the University Board of Trustees at its July 11 meeting. His appointment is effective Oct. 1, 2014.
An international team of researchers has discovered honey bee colonies in Newfoundland, Canada, that are free of the invasive parasites that affect honey bees elsewhere in the world. The populations offer a unique opportunity to investigate honey bee health, both with and without interfering interactions from parasites.
After a long winter, summer finally has arrived. And with the new season comes the activity of pollinators -- birds, bees, butterflies and more.
They're pesky creatures that always seem to ruin your backyard summer barbecue, but now researchers say they're closer to figuring out why.
To enhance infectious disease research training in low- and middle-income countries, NIH has awarded grants totaling $5.2 million to five institutions. Funding from Fogarty's Global Infectious Disease Research Training (GID) program will provide five years of support to new and ongoing projects in Colombia, South Africa, Tanzania, Thailand and Uganda.

Parasites, lack of food, cold snaps, pesticides, and poor management all can stress honeybee colonies, making it difficult to pin their collapse on a single source. However, in controlled field tests, honeybee colonies show evidence of Allee effects (a positive correlation between population size and individual fitness) and tipping points that are early warning indicators of collapse, MIT physics graduate student Lei Dai says.
On May 7, 2014, ESA members Gary Felton and Holly Holt visited Washington, DC to speak to lawmakers and to attend the Coalition for National Science Funding Exhibition & Reception, where they discussed their research and the importance of investment in federal science agencies, such as the National Science Foundation (NSF) to support entomology research and training.
Biologist seeks to unravel the genetics behind adaptive radiation and mimicry.
Three Penn State faculty members have been named Evan Pugh Professors, the highest distinction bestowed by the University on its faculty. Including these most recent honorees, only 65 have received these professorships since the title’s inception in 1960.
Recently, there has been a lot of press related to pollinator health, and some troubling information indicates that certain fungicides, when used during bloom, can negatively affect the health of honey bees. This is a complicated problem with the solutions relying on understanding the detailed relationships among chemicals, pollinators and pest management needs. It is not prudent to treat this topic with a broad brush with statements such as "All neonicotinoid insecticides are bad for all pollinator species," or "No fungicides should be sprayed during bloom." Research is on-going, and we do not know all of the details yet.
This is the First of twelve short news articles written by students, during the professional development class, about each other's research.
What can ants teach us about the transmission and spread of human disease? Perhaps a lot, according to a team of researchers who recently received a grant of more than $1.8 million from the National Science Foundation to explore this question.
Several parasites and pathogens that devastate honeybees in Europe, Asia and the United States are spreading across East Africa, but do not appear to be impacting native honeybee populations at this time, according to an international team of researchers.
