A sex attractant for the Siberian moth Dendrolimus superans sibiricus (Lepidoptera : Lasiocampidae)

Field trapping experiments were conducted against the Siberian moth, Dendro limus superans sibiricus Butler, in Siberia, Russia, using traps baited wit h a virgin female moth or 100 mu g synthetic mixtures of C-12 straight chai n-length aldehydes, alcohols, and acetates alone or in combinations on rubb er septa. Traps baited with a 1:1 blend of aldehydes and alcohols captured many males. The capture rate was similar to the rate of capture seen in tra ps baited with virgin females. The mixture of aldehydes and alcohols (64% Z ,E-5,7-dodecadienal, 10% Z-5-dodecenal, 18% E-7-dodecenal, 8% E-6-dodecenal ) and (64% Z,E-5,7-dodecadien-1-ol, 10% Z-5-dodecen-1-ol, 18% E-7-dodecen-1 -ol, 8% E-6-dodecen-1-ol) can be used as a sex attractant to monitor endemi c Siberian moth populations in Asia, and for surveillance and detection of the moth in countries where the insect might be accidentally introduced.
