Scientists are trying to design the last malaria control agent the world will ever need.
Letting mosquitoes reproduce rather than killing them as fast as possible could be the key to controlling malaria epidemics.
Two graduate students in Penn State's College of Agricultural Sciences -- Abby Kalkstein and Holly Holt -- were recently awarded fellowships in pollinator health sponsored by ice cream-maker Häagen-Dazs.
Like many other activities, global health has fashions. For the past couple of decades AIDS has captured both the imagination and the research dollars. Recently, though, the focus has shifted towards malaria, which kills a million people a year, most of them children, and debilitates hundreds of millions more. Insecticide-impregnated bednets designed to stop people being bitten by infected mosquitoes are being scattered throughout Africa. New drugs based on a Chinese herb called Artemisia have been introduced. And researchers are vying with one another to be the first to devise an effective vaccine. But the traditional first line of attack on malaria, killing the mosquitoes themselves, has yet to have a serious makeover.
Honeybees in colonies affected by colony collapse disorder (CCD) have higher levels of pathogens and are co-infected with a greater number of pathogens than their non-CCD counterparts, but no individual pathogen can be singled out as the cause of CCD, according to a new study by researchers from Penn State's College of Agricultural Sciences, other universities and the U.S. Department of Agriculture's Agricultural Research Service.
Western bean cutworm has been found in Pennsylvania for the first time. This caterpillar species could develop into a significant pest of Pennsylvania field corn and sweet corn in the coming years.
Daytime temperature fluctuations greatly alter the incubation period of malaria parasites in mosquitoes and alter transmission rates of the disease. Consideration of these fluctuations reveals a more accurate picture of climate change's impact on malaria.
Congratulations to Dr. Tom Baker, Professor of Entomology, for being selected as ESA Fellow. The designation of Fellow recognizes individuals who have made outstanding contributions to Entomology. Dr. Baker will be specially recognized at the 2009 Annual Meeting of the Entomological Society of America.
Xerces Society and multiple partners will work to understand and protect habitat for pollinators and other beneficial insects. In response to this concern the Natural Resource Conservation Service has awarded two grants to the Xerces Society for Invertebrate Conservation.
Researchers in Penn State's College of Agricultural Sciences -- funded by a grant of approximately $2.5 million from the U.S. Department of Agriculture -- will study the interaction between weed, insect and soil-management methods for organic production of small grains, corn and soybeans.
Killing just the older mosquitoes would be a more sustainable way of controlling malaria, according to entomologists who add that the approach may lead to evolution-proof insecticides that never become obsolete.
A researcher in Penn State's College of Agricultural Sciences is the recipient of the prestigious 2008 Wolf Prize for Agriculture for his scientific contributions in the field of chemical ecology.
Honeybees across the country are dying by the millions due to Colony Collapse Disorder and other environmental factors. But homeowners and gardeners can chip in to promote healthy honeybee populations, thanks in part to the educational efforts of Penn State Master Gardeners.
s the pollination season approaches in Pennsylvania and the Northeast, scientists at Penn State and elsewhere continue to seek answers to the decline of the nation's honeybees and other pollinators, which are critical to the production of $15 billion worth of crops in the United States. To assist in this effort, a major ice cream brand has stepped up to support honeybee research and education.
A little-known fungus tucked away in the gut of Asian longhorned beetles helps the insect munch through the hardest of woods according to a team of entomologists and biochemists.
Colony Collapse Disorder continues to take a devastating toll on U.S. honey bee populations, but Pennsylvania beekeepers on average fared better than their counterparts nationally during this past winter.

Researchers in the college are making progress in pinning down the causes of Colony Collapse Disorder, a mysterious ailment that threatens the beekeeping industry and the crops that rely on honey bee pollination.
