Abstract: [Objectives]  To investigate whether sex pheromones extracted from the ovary of the cheese skipper, Piophila casei, are effective lures for trapping males of this species. [Methods]  The behavioral and electroantennogram (EAG) responses of male cheese skippers to ovarian extracts were measured, and an experiment comparing the effectiveness of different trapping lures was conducted in a simulated warehouse. [Results]  Significantly more male cheese skippers choose the ovarian extract than the control (acetone). EAG results indicate that all tested doses of the extract elicited EAG responses from males, and all tested doses trapped more males than the control in a non-choice experiment. A choice experiment indicated that a dose equivalent to the amount of pheromone obtained from 2 females was the most attractive to males. [Conclusion]  The ovarian extract of female cheese skippers was significantly more attractive to males than a control substance.
