trolled environment or laboratory are
not always successful in field tests,"
explains H.C. Huang, a plant
pathologist at Lethbridge.
"For one thing, the lower humidity
in the field may prevent the micro-
organisms from increasing rapidly
enough to control the larger insects."
Determining the effectiveness of
the agent in controlling insects is only
part of the job. The scientist must
also see if it harms beneficial insects
and ensure that it has no ill effects on
humans, plants, or farm and
domestic animals.
"These precautions slow down the
development of new biological con-
trol agents, but they are necessary to
prevent any unforeseen catastrophes
and to protect the health of the
public," Dr. Harper says. E1
Dictionary of Farm
Animal Behaviour
A new Dictionary of Farm Animal
Behaviour has been produced at the
University of Guelph. Designed to br-
ing precision to this rapidly expan-
ding field, the book includes collo-
quial expressions and their accepted
definitions.
Authors are University of Guelph
professor Frank Hurnik, an animal
behavior specialist, Guelph Ph.D.
student Bruce Webster, and Paul
Siegel, a Virginia Polytechnic Univer-
sity faculty member, well-known for
his research in behavioral genetics.
Although written with students in
mind, the dictionary should be useful
to anyone who deals with animals.
Hurnik explains that there is a grow-
ing awareness of the need to unders-
tand animal psychology to achieve
optimum performance from animals,
a need that is reflected in a course
called "Behavior and Bionomics"
now given at the university.
Although animal behavior is in-
teresting in its own right, Hurnik
believes that there is much potential
for improving production perfor-
mance by making the environment
more harmonious. "Modern
technology has to be designed to suit
the animals," he says. "It is easier to
adapt the environment than it is for
the animals to have to adjust. Space,
equipment, and procedures should be
planned carefully for the benefit of
the animals."
The dictionary is available for $15
(prepaid) from the Office for Educa-
tional Practice, University of Guelph,
Guelph, Ontario, NIG 2W 1. !l
