Abstract In north-central Georgia, trap height affected catches of some species of bark and woodboring beetles (Coleoptera) in traps baited with lures used in surveillance programs to detect non-native forest insects. Traps were placed within the canopy and understory of mature oak trees (Quercus spp.) with collection cups placed 18–23 m above ground level (AGL), and 0.3–0.5 m AGL, respectively. Traps were baited with ethanol to target ambrosia beetles (Curculionidae: Scolytinae) in one experiment, ethanol + syn-2,3-hexanediol + racemic 3-hydroxyhexan-2-one + racemic 3-hydroxyoctan-2-one to target hardwood woodborers (Cerambycidae) in a second experiment, and α-pinene + racemic ipsenol + racemic ipsdienol to target pine bark beetles (Curculionidae) and woodborers (Cerambycidae) in a third experiment. Canopy traps were more effective than understory traps for detecting Cnestus mutilatus (Blandford) (Curculionidae), Neoclytus scutellaris (Olivier), and Monochamus titillator (F.) (Cerambycidae). The reverse was true for Xylosandrus crassiusculus (Motschulsky), Dendroctonus terebrans (Olivier) (Curculionidae), and Neoclytus acuminatus (F.) (Cerambycidae). Catches of a third group which included Hylobius pales (Herbst), Ips grandicollis (Eichhoff) (Curculionidae), Neoclytus mucronatus (F.), and Anelaphus pumilus (Newman) (Cerambycidae) were largely unaffected by trap height. Similar patterns were noted for species of Cleridae, Scarabaeidae, Trogossitidae, and Zopheridae but not Histeridae or Tenebrionidae (Coleoptera). Catches of the bee assassin Apiomerus crassipes (F.) (Hemiptera: Reduviidae) in traps baited with the hardwood borer blend were greater in canopy traps than in understory traps.

The eastern pine weevil, Pissodes nemorensis Germar, and the pales weevil, Hylobius pales (Herbst), are major pests of pine production in eastern North America. Ethanol- and turpentine-baited pitfall traps and flight traps, and pit traps baited with fresh pine billets, were used to characterize weevil species composition in north-central Kentucky (USA) and assess seasonal activity by exploiting the weevils' attraction to host plant volatiles. During the 1998 growing season, P. nemorensis was the predominant species, comprising over 95% of the total trap catch for the season. Weevils were most responsive to fresh pine billets in pit traps, followed by ethanol- and turpentine-baited flight traps, and ethanol- and turpentine-baited pitfall traps. The sex ratio of P. nemorensis captured in pit traps was male biased, and in pitfall traps it was weakly female biased. Flight trap catch in traps placed 0.8 m above ground level was female biased. More weevils were captured in flight traps at 0.8 m than in flight traps at 1.6 m. Catches were greatest in traps placed perpendicular to the slope. Although H. pales was present at the site, numbers captured were too low to statistically assess trap efficacy.

The black turpentine beetle, Dendroctonus terebrans (Olivier), or BTB, is one of five common species of pine bark beetles in the southeastern United States. Black turpentine beetles bore into the inner bark of stressed or injured pines (Pinus spp.), where they breed and feed on phloem tissue. Adults are strongly attracted to volatile pine odors and readily breed in fresh stumps. Attacks on standing trees usually occur on the lower 1 to 2 m of the trunk or on large roots. Light attacks may kill only localized sections of phloem tissue, but numerous attacks per stem result in tree mortality. Infestations commonly occur in pine stands affected by recent logging activity (e.g., thinning), fire, mechanical injury, storm damage, climatic stress, or competition (USDA Forest Service 1985, Dixon 1986). This document is EENY-356, one of a series of the Department of Entomology and Nematology, UF/IFAS Extension.

AbstractResults of a field experiment indicate that adults of the pine weevil Hylobius pales (Herbst) respond to pheromones of bark beetles. Each sex of H. pales was more attracted to traps baited with the combination of a pine bolt infested with male Ips calligraphus Germar plus the synthetic Dendroctonus Erichson pheromones frontalin and exo-brevicomin, than to traps baited with pine bolts alone. The combined numbers of male and female H. pales caught in traps baited only with Ips calligraphus-infested bolts were significantly greater than numbers caught in traps baited with uninfested control bolts. The attraction of H. pales to bark beetle pheromones may represent a kairomonal response in which weevils exploit semiochemicals from other species that signify a suitable host resource.

Survey Results

Soil-dwelling millipedes were methodically hand-sampled in two second-rotation Pinus radiata stands in Stoodley Plantation in north-central Tasmania. Eleven of 14 species collected were natives, and native millipedes comprised 83% of the 1 456 identified specimens. The average millipede catch in 40 x 0.5 m2 quadrats was 74 individuals/m2. All nine of the native species of Chordeumatida, Polydesmida and Polyzoniida found in the survey had previously been collected in native forest within a 10 km radius of the pine plantation. Historical records indicate that Stoodley Plantation was established on abandoned farmland, and the two sampled areas have carried P. radiata for at least 60 years. The survey results support the suggestion that plantation development on cleared farmland can assist in local-scale conservation of native invertebrates.

Pine Bark Beetles

Pheromone-baited traps are frequently used for research or in monitoring populations of bark beetles such as the southern pine beetle, Dendroctonus frontalis Zimmermann, and Ips spp. which are important pests of southern pines. We compared the effectiveness of two commercially available trap designs, the multiple-funnel trap and the slot trap, for collection of D. frontalis, three species of Ips, and two of their common predators. Slot traps captured greater numbers of bark beetles while multiple-funnel traps captured more predators. Multiple-funnel traps were judged to be easier to transport and check in the field. This study indicates that slot traps are preferable for monitoring southern bark beetles with the least disruption to natural enemy populations, while multiple-funnel traps are better for monitoring bark beetle/predator ratios. Due to ease of checking and handling, multiple-funnel traps are preferable for uses that involve large numbers of traps, long-distance manual hauling, or frequent relocation of traps.
