Sammendrag: The attraction of the blowfly Calliphora vicina Robineau-Desvoidy,
1830 (Diptera: Calliphoridae) to single synthetic compounds, blends and authentic
odours was investigated in a wind tunnel. A total of 1850 C. vicina (1750 females
and 100 males) were tested. A comparison of male and female responses showed
significant differences in attraction between the sexes. Females were more attracted than males to liver odour. The attraction of females lay in the ranges of 0–22% for single compounds, 26–64% for synthetic blends and 58–88% for authentic
odours. Dimethyl trisulphide was the most attractive single compound. Significant
improvement in attraction was achieved with blends and a three-component lure,
consisting of dimethyl trisulphide, mercaptoethanol and o-cresol, was found to be
the best solution for field trapping of C. vicina. Authentic odours from dead fish and mice were significantly more attractive than liver and the three-component blend, and the blend and liver were similarly effective as attractants. Field tests support the results of the wind tunnel study and a high number of C. vicina were caught in funnel traps. Overall, 99.1% of the specimens caught were females.
