Activities at the Entomological Societies’ meeting
The 1997 joint annual meeting of the Entomological Society of Canada
and the Entomological Society of Alberta took place in Edmonton, 4-8 October
1997. The meeting was very well attended including a large number of student
members, many of whom presented papers. Items in the program or associated
with it included:
A plenary lecture by G.G.E. Scudder, entitled “Insects:
diversity, impacts and adaptations”
A plenary symposium on forest biodiversity
Symposia on Insects and ecosystem productivity, on Pollinators,
and on Fluctuating asymmetry
Workshops on Forest insect defoliators and Bt: a system
of multiple-trophic interactions, Biological control of pests of field
crops, Lygus bug management, and Communicating entomology
A student paper competition in several simultaneous sessions
The ESC Heritage Lecture, and the ESC Gold Medal Address
Governing Board and annual general meetings also took place, the Gold
Medal and other honours were awarded, and there were many opportunities
for informal exchange of information, including an opening reception. The
after-dinner speaker was the television host John Acorn, who spoke on “Bringing
Bugs to the Box . . .” Activities especially relevant to the work of the
Biological Survey included the following.
Plenary symposium on Forest biodiversity: What’s next?
Four major presentations outlined the diversity and importance of arthropods
in forest systems, and the significance of information about them. These
Forestry and Fennoscandian boreal insects: where are
we and where should we go? J. Niemelä
Importance of integrating arthropods in the criteria
and indicators of sustainable development in forestry. C. Hébert
The biodiversity of arthropods from northern temperate
ancient coastal rainforests: factual foundations or fictional myths. N.
The ‘natural disturbance paradigm’ and forest management:
magic bullet or biodiversity bingo? J. Spence
Symposium on insects and ecosystem productivity
Four major presentations treated the roles of insects in certain ecosystems,
The role of insects in grassland trophic structure and
energy flow. D. Johnson
Insects in northern prairie wetlands: functions and values.
A forest is more than trees; but show me one without
trees: do insects modulate forest productivity. J. Volney
Winter ticks on moose and mange mites on elk: do they
affect host population size? W. Samuel
Symposium on Pollinators and Mother Earth: Global perspectives in
productivity, diversity and behaviour
A wide range of presentations treated many aspects of pollination, especially
the many interactions involved.
Who buzzes for rare plants. V. Tepedino
Plant-pollinator interactions in a Mediterranean scrubland.
Bees and plants in a subtropical desert. C. Vergara
Pollinator communities, diversity and abundance, for
measuring ecosystematic stress. P. Kevan, C. Greco and S. Belaoussoff
Yucatan’s native bees: pollination, diversity, and economic
benefits. V. Melendez-Ramirez
The importance of native bees for lowbush blueberry production.
Floral visitors of stone fruit trees and weeds in the
Mexican plateau. C. Vergara
Conserving honeybees in the face of threats from parasitic
mite diseases: breading and medicament. M. Narr
Plant interactions for pollinator visits: A test of the
magnet species effect in Trillium grandiflorum. T. Laverty
Parasitoids and flower relations. J. Patt
Getting the message to the public: pollination interpretation
at the Toronto Metro Zoo. J. Ambrose
Dr. George Ball, the Chair of the Biological Survey project for a number
of years after its inception, presented an account of the early background
to, and the development of, the Biological Survey of Canada (Terrestrial
Arthropods). This lecture in the ESC Heritage series was entitled: “Pursuit
of insect biodiversity, Canadian style.” The text will be published in
the ESC Bulletin.
Papers on systematics and related themes
The following titles included some of the papers of faunal interest
that were presented in various scientific sessions, including posters,
in addition to the symposium and workshop papers. (Interesting treatments
on a range of other subjects such as biological control, pest management,
host resistance, behaviour, physiology and species interactions also were
presented at the meeting.)

originating from harvest and wildfire. C. Buddle
