Some symbiotic bacteria living inside Colorado potato beetles can trick plants into reacting to a microbial attack instead of a chewing herbivore, according to a team of Penn State researchers who found that the beetles with bacteria were healthier and grew better.
The Entomological Society of America is pleased to announce the winners of its 2013 awards. The awards will be presented at Entomology 2013, ESA's 61st Annual Meeting in Austin, TX from November 10-13, 2013.
The Entomological Society of America (ESA) is proud to announce the winners of the 2013 Entomology Student Travel Grants. These travel grants, which will help entomology students attend Entomology 2013 – ESA's Annual Meeting in Austin this November – are funded by USDA-NIFA's Agriculture and Food Research Initiative Program on Plant-Associated Insects and Nematodes. The grants were created to provide financial support to graduate students for new networking, presentation, and research opportunities
The Governing Board of the Entomological Society of America has elected ten new Fellows of the Society for 2013. The election as a Fellow acknowledges outstanding contributions to entomology in one or more of the following: research, teaching, extension, or administration. The following Fellows will be recognized during Entomology 2013 -- ESA's 61st Annual Meeting -- which will be held November 10-13, 2013 in Austin, Texas:
Induced plant defenses in response to herbivore attack are modulated by cross-talk between jasmonic acid (JA) - and salicylic acid (SA) - signaling pathways.
UNIVERSITY PARK, Pa. – The majority of our agricultural crops depend on pollinators, however pollinators are facing a number of stressors in their environment. These stressors and approaches to mitigating their effects were the focus of the 2nd International Conference on Pollinator Biology, Health and Policy held recently at Penn State.
Depictions of science in television and movies can affect individual health decisions, influence public policy, and inspire imagination. Practicing scientists who consult for the entertainment industry aim to help accurately communicate complex scientific topics, without forgetting that the story is king.
Guests include: Edwin Rajotte, professor of entomology at Penn State, Erik Stokstad, staff writer for Science and Brenda Eskenazi, professor at the school of public health at the University of California Berkeley.
Temperature-driven changes alter outbreak patterns of tea tortrix – an insect pest – and may shed light on how temperature influences whether insects emerge as cohesive cohorts or continuously, according to an international team of researchers. These findings have implications for both pest control and how climate change may alter infestations.
Congratulations to Dr. Consuelo De Moraes, Professor of Entomology, for being selected as ESA Fellow.
In a scene of the movie “World War Z,” hundreds — maybe thousands — of virus-infected people swarm at the base of a wall in Jerusalem to find more humans to bite and infect. These zombies then form a human ladder to charge over the wall, which Israel’s government had put up in the hope of sparing the city the wrath of the creatures.
“To the bee, a flower is a fountain of life, and to the flower, a bee is a messenger of love,” wrote poet Kahlil Gibran. Whether or not love is involved in the exchange, the evolutionary dance between pollen-transporting honey bees and nectar-producing flowers is one of nature’s most extraordinary symbiotic relationships, a hundred million years in the making.
Early registration continues for the International Conference on Pollinator Biology, Health and Policy as conference organizers have announced the final agenda.
Malaria-carrying mosquitos appear to be manipulated by the parasites they carry, but this manipulation may simply be part of the mosquitos' immune response, according to Penn State entomologists.
While unraveling a dramatic case of mind control, biologist David Hughes is taking calls from Hollywood—and gaining new insights into the role behavior plays in spreading disease.

A Web-based Penn State Extension course designed to help beginning and experienced beekeepers gain the knowledge they need to be successful has been recognized for online excellence.
The geographic location of Brood II in Pennsylvania is in wooded/forested areas in the eastern 1/3 of our state in Berks, Bucks, Carbon, Chester, Dauphin, Delaware, Lancaster, Lebanon, Lehigh, Luzerne, Monroe, Montgomery, Northampton, Philadelphia, Pike, Schuylkill, and Wyoming counties. We have 8 different broods of the periodical cicadas in Pennsylvania all of which require 17 years to reach maturity. In addition to eastern Pennsylvania, members of Brood II will also emerge in most of Connecticut, New Jersey, southeastern New York, Maryland, central Virginia, and extreme north central North Carolina. Periodical cicadas are unique to eastern North America and are found nowhere else in the world. The emergence of periodical cicadas often begins in mid- to late May when soil temperatures are approximately 64°F. I've observed over the years in Pennsylvania that the start of the mass emergence of periodical cicadas is usually preceded by a warm rainfall event.
Since formation of the Colony Collapse Disorder (CCD) Steering Committee early in 2007, the U.S. Department of Agriculture (USDA), U.S. Environmental Protection Agency (EPA) and public and private partners have invested considerable resources to better address pollinator declines and major factors adversely affecting bee health. Several individuals from the Committee, along with Pennsylvania State University, organized and convened a conference on in October 2012 that brought together stakeholders with expertise in honey bee health. This new report is the product of unprecedented collaboration and shows that there is much work yet to do. The key findings are summarized below.
The danger that the decline of bees and other pollinators represents to the world’s food supply was highlighted this week when the European Commission decided to ban a class of pesticides suspected of playing a role in so-called “colony collapse disorder.”
