A new multimillion
dollar biocontainment facility at Agriculture and Agri-Food
Canada's (AAFC)
Lethbridge
Research Centre will dramatically expand Canada's capacity
for leading-edge biocontrol research.
The facility will include
a laboratory built to Bio Safety Level three (BSL-3) standards
and will be one of the top three of its kind in the world, says
Dr. Peter Burnett, Acting Director of the Centre. The facility
is part of a broader, multi-year Centre expansion and upgrade
slated for completion this fall, which will boost overall
research capacity by 30 percent. "This state-of-the-art
biocontainment facility is the type of resource Canada needs to
position itself among the world leaders in biocontrol research
for the long-term," says Burnett. "Every effort has been made to
ensure it offers our researchers the very best in both
technology and utility."
Biocontrol has emerged as
one of the most promising pest control approaches, says Dr. Rose
DeClerck-Floate, biocontrol researcher and user representative
on the Centre expansion committee. It involves using living
organisms - such as insects that feed on weeds or pest insects -
as control agents. Advantages of biocontrol include targeting,
cost-efficiency, long-term effectiveness and reduction in
pesticide use. Researchers will use the new facility to develop
biocontrol agents against weeds, insects and pathogens, using
either beneficial insects or microbes.
"Biocontrol is still
gaining acceptance as a tool in crop production and range
management, but it has tremendous potential," says
DeClerck-Floate. "The new facility will greatly improve our
ability to evaluate potential biocontrol agents and develop them
as practical tools for pest management
strategies." The
biocontainment facility will include components for work with
insects and insect or plant pathogens, she says. Parts used for
pathogen research have been built to BSL-3 standards, which
means they are designed to handle agents with potential for
airborne transmission. The standards include a combination of
practices and procedures and facility containment
specifications. Among the facility's many security features is a
negative air pressure system to prevent the escape of airborne
particles.
"The facility was
built based on the latest knowledge, with input from experts
around the world," says DeClerck-Floate. "Throughout design and
construction, we showed our plans to researchers and listened to
their advice, and we toured similar facilities to borrow from
their best elements."
The design was tailored
for each component of the facility, she adds. "For example, to
design the insect containment areas, we kept natural insect
behaviour in mind. Many insects prefer natural light for
development or mating, so windows were provided in the rearing
rooms. Walls were also
painted light colours so we can see insects if they try to
escape, and ceilings were kept low for easy re-capture."
Including the
biocontainment facility, the Lethbridge Research Centre
expansion will feature 13 new laboratories and associated
offices, along with insect rearing facilities, a food research
facility and a new greenhouse complex.
Biocontrol research at
Agriculture and Agri-Food Canada's Lethbridge Research Centre
illustrates the government's commitment to promote innovation
for growth, maintain the security of the food system and protect
the health of the environment, as proposed in the new
Agricultural Policy Framework. The Framework aims to increase
profitability for producers by giving them the tools and
capabilities to respond to constantly changing consumer demands
for safe food produced in an environmentally responsible way. |
