Should ipsdienol and ipsenol lures be retained in a generic trap lure blend for pine bark and woodboring beetles (Coleoptera) in the southeastern United States?
Journal of Entomological Science 58 (2), 230-241
Abstract: Trap lure blends that maximize the diversity of captured insect species help to reduce the costs of detection programs that target native and nonnative invasive species of bark and woodboring beetles. In 2007, the effects of the bark beetle pheromones ipsdienol and ipsenol on catches of beetles (Coleoptera) in multiple-funnel traps baited with ethanol + α-pinene were evaluated in a trapping study in one stand of mature loblolly pine, Pinus taeda L., in northcentral Georgia. Ipsenol and/or ipsdienol increased catches of Acanthocinus obsoletus (LeConte) and Monochamus titillator (F.) (Cerambycidae), Ips avulsus (Eichhoff), Ips calligraphus (Germar), Ips grandicollis (Eichhoff) (Curculionidae), Temnoscheila virescens (F.), and Aulonium tuberculatum (LeConte) (Zopheridae) in traps baited with ethanol and α-pinene. However, catches of most species in traps baited with ipsenol + ipsdienol were the same as those baited with either ipsenol or ipsdienol alone. Only catches of I. avulsus were greatest in traps baited with both ipsdienol and ipsenol. Catches of Thanasimus dubius (F.) (Cleridae), Platysoma spp. (Histeridae), and Lasconotus spp. (Zopheridae) increased with the addition of ipsenol but decreased with the addition of ipsdienol. In contrast, catches of Orthotomicus caelatus (Eichhoff) (Curculionidae) increased with the addition of ipsdienol; attraction was interrupted by the addition of ipsenol. A number of trade-offs exist in retaining ipsdienol and/or ipsenol in the multicomponent pine lure blend for detection programs in Georgia.
