Abstract
Insect pheromones and other insect semiochemicals have been concentrated in capillary traps for thermal desorption and gas chromatographic separation. Whereas highly volatile compounds are not quantitatively retained by traps short enough to enable thermal desorption in the injector, quantitative trapping is possible on longer fused silica traps. Short traps coated with a 145 μm film of a polysiloxane were used for the quantitative determination of the constituents of a dung beetle attractant. By means of a “living detector” with the antenna of an insect as sensing element the compounds eluting from a gas chromatographic column, were screened for possible semiochemical activity.
