Reduction in the pheromone attractant response of Orthotomicus erosus (Woll.) and Ips sexdentatus Boern. (Col., Scolytidae)

Under field conditions, the pheromone attractant responses of the scolytids Orthotomicus erosus and Ips sexdentatus were significantly reduced by the addition of one of the oxidation products of alpha-pinene, verbenone, to the attractive volatiles 2-methyl-3-butene-2-ol plus ipsdienol. Catches in fl...

Summary:Under field conditions, the pheromone attractant responses of the scolytids Orthotomicus erosus and Ips sexdentatus were significantly reduced by the addition of one of the oxidation products of alpha-pinene, verbenone, to the attractive volatiles 2-methyl-3-butene-2-ol plus ipsdienol. Catches in flight barrier traps also decreased when (S)-cis-verbenol was added to the dual bait mixture. The inhibitory action of the terpene alcohol was more noticeable upon female populations of both species. The observed patterns of behaviour might reflect the outcome of a long process of competition among Ips species
