摘要
We evaluated the attraction ofMonochamus alternatus Hope （Coleoptera： Cerambycidae）, Dryocoetes luteus Blandford and Orthotomicus erosus Wollaston （Coleoptera： Curculionidae： Scolytinae） to multiple-funnel traps baited with the pine volatiles, ethanol and （＋）-α-pinene and the bark beetle pheromones, ipsenol and ipsdienol. M. alternatus were attracted to traps baited with ethanol and （＋）-α-pinene but not those baited with ipsdienol and ipsenol. Ipsdienol and ipsenol decreased catches ofM. alternatus in traps baited with ethanol and （＋）-α-pinene. Traps baited with either binary combinations of ethanol and （＋）-α-pinene or ipsdienol and ipsenol were attractive to D. luteus and O. erosus. The addition of ipsenol and ipsdienol to traps baited with ethanol and （＋）-α-pinene synergized attraction of O. erosus but not D. luteus .
