Sammendrag:

Attracting high numbers of adult females, extensive
trapping prior to damage, and a pest species with a
predominantly univoltine lifecycle, are important factors
contributing to the success of mass-trapping programs. We
conducted a mass-trapping experiment over 4 years, using
yellow sticky traps and odor-baited funnel traps for control
of the blowfly Calliphora vicina in stockfish production
areas in Loften, Norway. Blowfly-related damage to fish in
five mass-trapping sites was compared with damage at five
control sites. Population monitoring established a connection
between blowfly activity and damage. Blowfly activity
in the period from mid-April to mid-May was correlated
with damage to fish in the same year. Interception (sticky)
traps, based on visual cues, caught blowflies during the
early drying period, whereas odor-baited funnel traps were
more effective during the later drying period, and continued
to catch flies throughout the year until late autumn. In the
funnel traps, 80% of the captured flies were females.
Compared to control sites, mass trapping reduced overall
damage to stockfish by 8–31%. In the final year of the
experiment, we compared mass-trapping and control treatments,
controlling for drying time period and sun exposure
(which both contribute to damage), and found a damage
reduction of 63%. Thus, mass-trapping with a femaleattracting
kairomone, and using traps of different functionality
to extend the critical trapping period, in accord with
pest phenology, is an efficient method for control of C.
