ARS scientists test improved stink bug trapping methods

2013-01-18
(Press-News.org) This press release is available in Spanish.

Baited black traps in a pyramid shape attract significantly more brown marmorated stink bugs than other traps, according to U.S. Department of Agriculture (USDA) scientists. Evaluating stink bug responses to different visual stimuli may help manufacturers design better traps for monitoring the bugs.

Entomologist Tracy Leskey at the Agricultural Research Service (ARS) Appalachian Fruit Research Station in Kearneysville, W.V., focused on visual stimuli that can attract the stink bugs to traps that will help farmers monitor the level of infestation in their fields and orchards.

ARS is USDA's principal intramural scientific research agency, and this research supports the USDA priority of promoting international food security.

In field trials in 2009 and 2010, Leskey and her colleagues found that significantly more stink bug adults and juvenile bugs, called nymphs, were captured in the baited black pyramid traps than in other traps. The researchers also found that more adults and nymphs were captured in a trap placed on the ground than in a commercially available trap hung from a tree limb.

These prototype pyramid traps may serve as monitoring tools to assess the presence, abundance and seasonal activity of pests and natural enemies to determine the need for insecticide applications.

Leskey and her colleagues also found that in 2010, 2011 and 2012, stink bugs produced two generations in one year in Kearneysville, based on the presence of eggs and newly molted adults in field cage experiments. Although it has been reported that these bugs produce only one brood annually in eastern Pennsylvania, it appears that in more southerly locations within the Mid-Atlantic region, they can produce two generations per year, according to Leskey.

A more extensive study is being replicated in several states on the East Coast to determine how many generations may be produced annually in those locations.

Studying ancient Earth's geochemistry

2013-01-18
Washington, D.C.— Researchers still have much to learn about the volcanism that shaped our planet's early history. New evidence from a team led by Carnegie's Frances Jenner demonstrates that some of the tectonic processes driving volcanic activity, such as those taking place today, were occurring as early as 3.8 billion years ago. Their work is published in Geology. Upwelling and melting of the Earth's mantle at mid-ocean ridges, as well as the eruption of new magmas on the seafloor, drive the continual production of the oceanic crust. As the oceanic crust moves away ...

Wild animals may contribute to the resurgence of African sleeping sickness

2013-01-18
Wild animals may be a key contributor to the continuing spread of African sleeping sickness, new research published in PLOS Computational Biology shows. The West African form of the disease, also known as Gambiense Human African trypanosomiasis, affects around 10,000 people in Africa every year and is deadly if left untreated. The disease is caused by a brain-invading parasite transmitted by bites of the tsetse fly, and gets its name from the hallmark symptoms of drowsiness and altered sleeping patterns that affect late-stage patients, along with other physical and neurological ...

Factors linked with survival differences between Black, White kidney failure patients

2013-01-18
Highlights Residence in areas with higher average household income was linked with improved survival in kidney failure patients. In White patients, income inequality was associated with mortality. In Black patients exclusively, residence in highly segregated areas was associated with increased mortality. More than 590,000 Americans in 2010 were treated for kidney failure. Washington, DC (January 17, 2013) — Complex socioeconomic and residential factors may account for differences in survival between Black and White kidney failure patients, according to a study ...

Climate events drive a high-arctic vertebrate community into synchrony

Climate events drive a high-arctic vertebrate community into synchrony
2013-01-18
Climate change is known to affect the population dynamics of single species, such as reindeer or caribou, but the effect of climate at the community level has been much more difficult to document. Now, a group of Norwegian scientists has found that extreme climate events cause synchronized population fluctuations among all vertebrate species in a relatively simple high arctic community. These findings may be a bellwether of the radical changes in ecosystem stability that could result from anticipated future increases in extreme events. The findings are published in the ...

Scientists expose new vulnerabilities in the security of personal genetic information

2013-01-18
CAMBRIDGE, Mass. (January 17, 2013) – Using only a computer, an Internet connection, and publicly accessible online resources, a team of Whitehead Institute researchers has been able to identify nearly 50 individuals who had submitted personal genetic material as participants in genomic studies. Intent on conducting an exercise in “vulnerability research”—a common practice in the field of information security—the team took a multi-step approach to prove that under certain circumstances, the full names and identities of genomic research participants can be determined, ...

Mouse research links adolescent stress and severe adult mental illness

2013-01-18
Working with mice, Johns Hopkins researchers have established a link between elevated levels of a stress hormone in adolescence — a critical time for brain development — and genetic changes that, in young adulthood, cause severe mental illness in those predisposed to it. The findings, reported in the journal Science, could have wide-reaching implications in both the prevention and treatment of schizophrenia, severe depression and other mental illnesses. "We have discovered a mechanism for how environmental factors, such as stress hormones, can affect the brain's physiology ...

How the brain copes with multi tasking alters with age

2013-01-18
The pattern of blood flow in the prefrontal cortex in the brains alters with age during multi-tasking, finds a new study in BioMed Central's open access journal BMC Neuroscience. Increased blood volume, measured using oxygenated haemoglobin (Oxy-Hb) increased at the start of multitasking in all age groups. But to perform the same tasks, healthy older people had a higher and more sustained increase in Oxy-Hb than younger people. Age related changes to the brain occur earliest in the prefrontal cortex, the area of the brain associated with memory, emotion, and higher decision ...

It's a dog's life: Doggy database aims to define pet health

2013-01-18
Using data collected about Labrador Retrievers, research published in BioMed Central's open access journal BMC Veterinary Research is beginning to quantify the health, illnesses, and veterinary care of dogs. The UK is a nation of pet lovers – but what do we know about the health of our pets? To date the long term (longitudinal) study of canine diseases has been patchy, relying on information from referral centers and details about pet illnesses which are not reported to a vet have never been studied before. The Dogslife internet-based project was organized in conjunction ...

Savanna study highlights African fuelwood crisis

2013-01-18
The dwindling reserves of fuelwood in Africa have been illuminated in a new study published today, which shows a bleak outlook for supplies across savannas in South Africa. Presenting their findings in IOP Publishing's journal Environmental Research Letters, researchers have found that at current consumption levels in the communal areas of Lowveld, South Africa, reserves of fuelwood could be totally exhausted within 13 years. The consequences are significant, with around half of the 2.4 million rural households in the country using wood as their primary fuel source, ...
