Interpretive Summary: The Siberian moth is a dangerous pest of conifer forests in Siberia and Far East Russia and is a potential pest of forests in the United States. A sex attractant for the Siberian Moth had been discovered and tested in Siberia but it was not known if the chemical was biologically active against a moth population in the Novosibirsk region of Russia. Electrophysiological and behavioral tests using moths from Novosibirsk showed the attractant was as highly stimulatory to moths like it was in Siberia. This result indicates the sex attractant can be used by forest managers in Russia to monitor the species across much of its geographic range including the Novosibirsk region. The attractant will facilitate study of the moth's population dynamics in periods of low density, mating and migrating behavior. The attractant will also be useful to APHIS in monitoring at possible ports of entry in the United States and to monitor eradication efforts in case the pest becomes established in North America.

Technical Abstract: The biological activity of compounds, Z,E-5,7-dodecadienal, Z-5- dodecenal, E-7-dodecenal, E-6-dodecenal, Z,E-5,7-dodecadien-1-ol, Z-5-dodecen-1-ol, E-7-dodecen-1-ol, E-6-dodecen-1-ol and acetate esters of the alcohols, known to be involved in the attraction males of the Siberian moth in Siberian were compared to extracts of virgin female sex pheromone glands using behavioral and electrophysiological tests. Behavioral tests in Novosibirsk showed that a 1:1 synthetic mixture of dienal:dienol elicited a significant attraction response that was equivalent to female extracts. Addition of acetate to the binary mixture did not diminish the attractant effect. Electrophysiological tests showed that dienal and decenals had a greater stimulatory affect than the alcohols or female extracts.
