Ant Genome Sheds Light on How to be a Successful Pest (Jan
University of California - Berkeley.
A research team led by scientists at the University of California, Berkeley,
and San Francisco State University has unlocked the genetic code of the highly
invasive Argentine ant (Linepithema humile) - the tiny brown insect
that homeowners so frequently find marching en masse through their kitchens -
providing clues as to why this species has been so successful. The scientists
have also studied the draft genomes red harvester ant (Pogonomyrmex barbatus),
the red imported fire ant (Solenopsis
invicta) and the leaf-cutter ant (Atta cephalotes). Among the four
ant genomes being reported, the Argentine ant and the fire ant, both native to
South America, have established themselves in regions throughout the world, wreaking
havoc with the native biodiversity along the way.
Service Offers Free Guide to Managing Invasive Plants (Jan
Forest Service. Southern Research Station.
This new guide "A
Management Guide for Invasive Plants in Southern
Forests" provides homeowners, gardeners,
land managers and others information on controlling
and removing invasive plants in the South. The guide
provides information on developing strategies for
controlling 56 of the most pervasive invasive species
in the South.
the Itinerary of an Unwelcome Visitor (boll weevil) (Jan
have helped Texas cotton growers track down the likely
origins of a boll weevil infestation, provided guidance
on how to avoid future infestations and shed light
on how far the pest can travel under certain conditions.
The boll weevil was eliminated from much of the southern U.S.,
thanks to large-scale eradication efforts begun about
30 years ago, but it remains a problem in some areas,
and reinfestations are a constant threat. The researchers
looked at weather data and wind patterns on insect
movement and in this instance, determined the weevil
was brought in by Tropical Storm Erin in 2007. The
research was published in the Journal of the
Royal Society Interface article Multidisciplinary
fingerprints: Forensic reconstruction of an insect
reinvasion. Read more about the research in the
Solved: Detecting the Source, published in the
Jan 2011 issue of Agricultural Research magazine.
International Year of Forests (Jan 24, 2011)
International Union for Conservation of Nature.
The United Nations General Assembly declared 2011 as the International
Year of Forests to raise awareness on sustainable management, conservation
and sustainable development of all types of forests. Forests cover 31% of total
land area and are home to 80% of the world's terrestrial biodiversity. The IUCN Invasive
Species Specialist Group (ISSG) will celebrate the International Year of
Forests by focusing on raising awareness and disseminating information on the
impacts of invasive species -- forests pests and diseases.
Factors in Atrazine's Reduced Weed Control (Jan 19,
American Society of Agronomy.
Invasive broadleaf weeds can destroy corn crops and fallow fields. Farmers use
the chemical atrazine in herbicides to protect their plants. Despite the chemical’s
controversial environmental impacts, it can provide long term residual control
of many weed species. However, atrazine is losing its effectiveness, providing
a challenge for farmers in northeastern Colorado. Scientists at the USDA,
Agricultural Research Service's Water Management Research Unit and Colorado State
University conducted research to help growers learn how to predict if their fields
will lose atrazine effectiveness. The findings are published in the Journal
of Environmental Quality article Spatial
distribution of enhanced Atrazine degradation across Northeastern Colorado cropping
NeoBiota is a new peer-reviewed, open-access, rapid online journal launched to
accelerate research on all types of alien species and biological invasions: aquatic
and terrestrial, animals, plants, fungi and micro-organisms.
Red Imported Fire Ant Enemies in Place for Combat (Jan
USDA. Agricultural Research Service.
are releasing the fifth species of phorid fly to control
fire ant populations. Red
imported fire ants first arrived in the United States
in the early 1930s and have been expanding along the southern
portion of the country ever since, resulting in medical,
agricultural and environmental impacts that cost the U.S. public
billions of dollars each year. Read more about the research
in the article New
Red Imported Fire Ant Enemies in Place for Fight, published
in the Jan 2011 issue of Agricultural Research magazine.
