NEW GRASSHOPPER
MANAGEMENT CD-ROM
A new CD-ROM "Grasshoppers: Their Biology,
Identification and Management" is now available
from NPARL. The CD is a joint technology transfer
project of the United States Department of Agriculture's
Agricultural Research Service, the USDA's Animal and
Plant Health Inspection Service and the University of
Wyoming–Laramie and contains the latest research in
grasshopper management, identification, ecology, and
control tactics. It is a comprehensive source of
information on grasshoppers useful for researchers,
ranchers, land managers, extension agents and the
general public. Included on the CD are complete
versions of APHIS' "Grasshopper Integrated Pest Management User Handbook," R.E. Pfadt's "Field Guide to Common Western Grasshoppers" (and its accompanying
56 species fact sheets), J.L. Capinera and T.S. Sechrist's "Grasshoppers of
Colorado,"
and "Hopper 4.0" and "Carma 3.3," both decision support computer software. Also
included
is the latest research on using grazing management to reduce grasshopper
outbreaks, and
new grasshopper control methods which reduce pesticide application rates, costs
and
environmental concerns. The CD, edited by NPARL Research Entomologist David
Branson
and Technical Information Specialist Bethany Redlin, requires a web browser such
as
Internet Explorer or Netscape Navigator to view. The Grasshopper CD is free. If
you are
interested in receiving a copy please e-mail your request to hoppercd[at]sidney.ars.usda.gov.

Laboratory, Box 463, Sidney, Montana 59270. 406-433-2020. Plans also call for
the
information on the CD to be made available on the Internet later this summer.
SPURGEFEST II A
SUCCESS
TEAM Leafy Spurge's "Spurgefest II," held June 19-21 in Medora, N.D., went off
without a
hitch, with both planners and participants describing the event an overwhelming
success.
"Spurgefest II" was attended by nearly 300 ranchers, landowners, land managers,
and
representatives from numerous local, state and federal organizations and
agencies. The
three-day event featured a TEAM Leafy Spurge symposium, tours of
biologically-based
integrated pest management (IPM) research and demonstration sites, and a
hands-on flea
beetle collection demonstration. The latter proved particularly successful with
more than
three million flea beetles distributed to ranchers, landowners and land managers
from
throughout the region. Of those, more than 300,000 flea beetles were given to
representatives from two Canadian provinces along with additional distributions
to state
agency representatives from Iowa, Idaho and Nebraska. Baldo Villegas, an
entomologist
with the California Department of Food & Agriculture, left with enough
information and flea
beetles to start his state's first leafy spurge biocontrol program. Also
attending the event was
Lori Williams, executive director of the National Invasive Species Council, who
noted that
the TEAM Leafy Spurge program and events like Spurgefest provided great examples
of
bringing federal, state and local interests together in a united effort to
battle invasive weeds.
"This program is serving as a model and showing how coordination can help reduce
the
impact of invasive species." TEAM Leafy Spurge is a five-year IPM research and
demonstration project funded and led by the USDA-ARS in partnership with the
USDA-Animal & Plant Health Inspection Service. Sponsors for Spurgefest II
include the
USDA-ARS, USDA-APHIS, Theodore Roosevelt National Park/National Park Service,
the
U.S. Forest Service, the Bureau of Land Management, the BASF Corporation and Dow
Agrisciences Corporation. For additional information on TEAM Leafy Spurge, leafy
spurge

TEAM LEAFY SPURGE
PUBLISHES GRAZING MANUAL
If you're interested in using sheep to manage leafy
spurge, TEAM Leafy Spurge has just released a
must-read manual to answer many of your questions.
"Multi-Species Grazing and Leafy Spurge" is a full-color,
28-page how-to handbook that focuses on multi-species
grazing as a tool to manage leafy spurge, improve range
health and productivity, and potentially add a profitable
enterprise to existing ranch operations. Tim Faller,
director of the North Dakota State University-Hettinger
Research Extension Center and leader of the TEAM
Leafy Spurge multi-species grazing research and
demonstration project, says the manual is a particularly
good tool for ranchers who are new to the sheep
business. The manual covers all of the basics. Topics
include how multi-species grazing works, what can be
expected from multi-species grazing programs, diet
selection, stocking rates, fencing requirements, predation
and more. It also features an extensive section on economics, including models
that walk
ranchers through different economic scenarios to see if multi-species grazing is
a good fit for
their existing operation. The manual is available by calling 406-433-2020 or by
sending an
e-mail request to teamls[at]sidney.ars.usda.gov. It can also downloaded or viewed
on-line
from the TEAM Leafy Spurge website at
http://www.team.ars.usda.gov/grazingmanual.html.
TEAM LEAFY SPURGE
PUBLISHES "PURGE SPURGE" UPDATE
Evaluation copies of Version 4.0 of the award-winning
"Purge Spurge: Leafy Spurge Database" CD-ROM are
now available from TEAM Leafy Spurge. The CD
contains more than 800 journal articles, Extension
publications, symposium proceedings and abstracts and
other items pertaining to the management of leafy
spurge. Version 4.0 is the latest in a series of "Purge
Spurge" CDs first developed by then NPARL research
entomologist Neal Spencer and project manager Janet
(Petroff) Clark and last updated in 1995. Version 4.0,
produced by TEAM Leafy Spurge, brings the CD
up-to-date and also uses a new program, Adobe's
portable document format, to present the information. Version 4.0 Project
Manager/Editor
Bethany Redlin, a technical information specialist at NPARL, said the new format
was
chosen to provide better print quality and handling of graphics, figures and
tables, while still
providing easy-to-use navigational tools similar to those found on the original
CD (i.e. linked
table of contents, full-text search capabilities and search options by author,
title and
keyword). "Purge Spurge" earned Spencer a federal technology transfer award when
it was
initially released. To receive an evaluation copy of Purge Spurge Version 4.0,
contact Redlin
by mail at USDA-ARS NPARL, Box 463, Sidney, MT 59270; by phone at 406-433-9427,

FIELD TOUR INSPIRES
NEW BIOCONTROL EFFORT
TEAM Leafy Spurge has inspired the Carter County Weed Board in Carter County,
MT, to
institute their own biocontrol field day after board members toured TLS
demonstration plots
in Ekalaka on June 27. They joined 32 area producers, weed supervisors and
Extension
agents for the event which featured tours of herbicide and biocontrol plots
established by
TLS over the past several years. The board members were so impressed by the
success of
the TLS insectaries, that they're planning their own flea beetle sweeping and
distribution
effort for 2002, according to TEAM Leafy Spurge Coordinator Chad Prosser, "They
were
just real excited about the results from the bugs." During the TLS tour,
participants heard
presentations from Prosser on herbicide and biocontrol trials he was conducting
in the area
and from biocontrol experts Bob Richard of USDA-APHIS and Don Mundal of
NDSU-Fargo who discussed and demonstrated flea beetle collection and management
techniques. Participants then collected flea beetles from the demonstration
sites for
redistribution to their own properties. TEAM Leafy Spurge is a five-year IPM
research and
demonstration project funded and led by the USDA-ARS in partnership with the
USDA-Animal & Plant Health Inspection Service.

WHEAT STEM SAWFLY
RESEARCH UPDATE
Biological Science Technician Deb Waters traveled to Torrington, Wyoming and
Scotts
Bluff, Nebraska June 5th through the 8th to collect live wheat stem sawfly
specimens and
look for new infested sites. The collection is part of a larger biological
control research effort
under the direction of Research Entomologist Tom Shanower to map sawfly
infestations in
the Northern Great Plains and identify parasites to be used in the biological
control of the
pest. While in Wyoming, Waters identified three new infestation sites in Goshen,
Platte and
Laramie counties. Waters identified several new infestation sites in Goshen,
Platte and
Laramie counties in Wyoming and in Scotsdale, Banner, Morrell and Kimball
counties in
Nebraska. Waters will return to all sites this fall to collect samples before
the harvest. She
and Shanower will be looking for additional parasitoids that could potentially
serve as
biocontrol agents for managing wheat stem sawfly. Two braconids are currently
found in
Montana, with a third agent, an ichneumonid, currently in quarantine in the
APHIS Montana
State University biocontainment facility in Bozeman, MT. The live sawfly
specimens Waters
collected on her trip, along with specimens from the Sidney area, have been sent
to the
USDA-ARS European Biological Control Laboratory (EBCL) in Montpellier, France
for
DNA study. Drs. Marie-Claude Bon and Kim Hoelmer of EBCL will compare DNA from
several species of sawfly. This will help to target biological control by
focusing foreign
exploration efforts. The entire project is part of a multi-national,
multi-organizational effort to
improve biological control of wheat stem sawfly, a pest that causes more than
$100 million a
year in yield losses to northern Great Plains producers. Partners in the project
include
Montana State University – Bozeman, the European Biological Control Laboratory,
the
Sino-American Biological Control Laboratory and others.

ROLE OF FUNGI AS
EARLY INDICATORS OF SOIL QUALITY
Research Microbiologist Dr. TheCan Caesar has found that specific
soil-aggregating
basidiomycete fungi that serve as early biological indicators of soil quality in
the temperate
climate of the Northern Plains can also be used with tropical soils to aid in
evaluating
management practices. In an invited seminar at USDA-ARS-Pullman, WA on April 19,
Caesar presented findings stemming from research underway in the sloping
mountainous
areas of North Vietnam. In conjunction with her associates, Caesar has assessed
an upland
rice slash-and-burn cultivation system in terms of soil-aggregating
basidiomycete population,
microbial communities and total organic C and N in the soil. Recent data
indicated significant
changes in the biota and soil organic C and N due to management practices
(deforestation,
slash-and-burn and intensive tillage), reflecting land degradation. In deeper
(>20 cm), less
disturbed soil, management had little effect on microbial populations and
profiles. Dr. A. C.
Kennedy, research leader of the Pullman lab, worked with Caesar, utilizing FAME
(fatty
acid methyl ester) analysis of the Vietnamese soils. Caesar's work is part of a
collaborative
project with CIRAD (Centre International de Recherches en Agriculture pour le
Development, France), VASI (Vietnam Agriculture Science Institute, Vietnam) and
USDA-ARS that began late last year.

SCIENTIST SPEAKS IN
GUAM
Acting Laboratory Director Dr. Ernest S. Delfosse presented an invited Plenary
address
entitled "Management of Invasive Species: Integration of Science and Society" at
this
Congress on June 6. This presentation was very well-received, and prompted many
subsequent discussions on the integration of science and society. Dr. Delfosse
also took part
in an invasive species tour during the Congress, which highlighted the
environmental damage
caused by invasive weeds and by the brown tree snake, which has decimated native
bird
populations. A large number of customers and stakeholders from the Pacific
Region
attended the meeting, and provided valuable input to the Laboratory's role,
programs and
direction on invasive species.

SCIENTIST'S RESEARCH
FEATURED IN MEDIA
A study by Research Ecologist, Dr. Gregory Sword was featured this April in the
international German-language newspaper, Die Welt. The article summarized
Sword's recent
paper "Tasty on the outside, but toxic in the middle: Grasshopper regurgitation
and
gut-content mediated toxicity to a vertebrate predator" in the ecology journal, Oecologia.
Sword demonstrated how regurgitation by grasshoppers following consumption of
certain
toxic plants allows the grasshoppers to survive predator attacks. His study
provides an
answer to the commonly asked question, "Why do grasshoppers spit tobacco juice?"
These
findings also demonstrate how specific, often overlooked, grasshopper-host plant
interactions
can impact local predator-prey interactions and influence grasshopper population
regulation.
Similar synopses have recently appeared in the British publication, New
Scientist, and twice
in the Bozeman Daily Chronicle.
Sword was interviewed in late March by Science News magazine in connection with
an
article entitled "Touching legs turns shy locusts gregarious" published in the
March 31 issue
of the popular magazine. Science News contacted Sword for additional comments
concerning a paper by Simspon et al. that had appeared in the March 27 issue of
the
Proceedings of the National Academy of Science (Vol 98:3895-3897). This paper
described
how stimulation of mechanosensory hairs on the legs of locusts causes the
insects to
transform from solitary living individuals into gregarious, swarm-forming
locusts. Sword is
involved in the study of locust ecology and behavior, and the Science News
article discussed
some of his recent research on the expression of warning coloration in
gregarious phase
locusts. A photograph of gregarious and solitary phase Desert Locust juveniles
provided by
Sword accompanied the Science News item.
Most recently, on June 20, Gregory Sword appeared via phone in a live on-air
interview for a
popular radio news show in New Zealand. Sword was interview by Kim Hill of the
"Kim Hill
Show" broadcast on Radio New Zealand daily from 9am to noon NZ time. He was
asked to
comment on the global locust and grasshopper situation, as serious outbreaks
currently
threaten China, central Asia, and the western US. Issues discussed included the
causes of
locust and grasshopper outbreaks, prevention versus crisis management,
environmental and
economic aspects of control, and the often-popularized use of ducks as locust
biocontrol
agents in China.

GRASSHOPPER,
MORMON CRICKET WORK IN WYOMING
Research Ecologist Dr. Gregory Sword visited the University of Wyoming from
April 16-18.
Sword met with Dr. Jeffery Lockwood to discuss potential grasshopper management
research collaborations as well as ongoing and future USDA/ARS-University of
Wyoming
technology transfer projects. Sword also delivered an invited seminar to the
University of
Wyoming, Department of Renewable Natural Resources entitled, "Is the Mormon
cricket a
katydid or a locust? What the ecophysiology of the Desert locust may teach us
about the
Mormon cricket." On April 19, Sword traveled to Basin, WY where he met with Alan
Pomeroy, Supervisor, and Joel Lee, Asst. Supervisor, of the Big Horn County Weed
& Pest
Control District. They discussed the local Mormon cricket situation and
collected juveniles
for use in experiments to determine the ecological mechanisms that produce
damaging
Mormon cricket outbreaks. By understanding how and why these outbreaks occur,
Sword's
goal is to develop preventative rather than reactive Mormon cricket management
strategies.

AWARD-WINNING
NPARL OUTREACH IN NORTH DAKOTA
On May 14, Plant Pathologist Tony Caesar and Acting Lab Director Del Delfosse
took part
in the first "Marketplace for Kids" in Williston, ND, earning ARS an "Innovative
Thinker
Award" through their efforts. Approximately 700 regional 4th-6th graders
attended this
special event, whose planners designed it to encourage creative problem-solving
and
higher-level thinking, to develop cooperative entrepreneurial skills, and to
increase awareness
of career options. Delfosse presented a PowerPoint talk during each of the
morning and
afternoon sessions entitled "The World of Bugs." This inventive, interactive
presentation
focuses on the role of arthropods in the ecosystem, highlights entomology and
ecology as
career options, and as a grand finale, builds an insect out of volunteers from
the audience.
Caesar operated a very popular USDA-ARS booth, and distributed a lot of
age-appropriate
material to kids and teachers in attendance. The meeting was sponsored by Kent
Conrad
(U.S. Senator, North Dakota), Roger Johnson (North Dakota Commissioner of
Agriculture)
and Wayne Sanstead (Superintendent of Public Instruction), who presented the ARS
representatives with its "Innovative Thinker Award."
