Spreng., mortality in the southern United States. Effective traps and lures are needed to monitor spread of the beetle and for early detection at ports-of-entry, so we conducted a series of experiments to find the best trap design, color, lure, and trap position for detection of X. glabratus. The best trap and lure combination was then tested at seven sites varying in beetle abundance and at one site throughout the year to see how season and beetle population affected performance. Manuka oil proved to be the most effective lure tested, particularly when considering cost and availability. Traps baited with manuka oil lures releasing 5 mg/d caught as many beetles as those baited with lures releasing 200 mg/d. Distributing manuka oil lures from the top to the bottom of eight-unit funnel traps resulted in similar numbers of X. glabratus as a single lure in the middle. Trap color had little effect on captures in sticky traps or cross-vane traps. Funnel traps caught twice as many beetles as cross-vane traps and three times as many as sticky traps but mean catch per trap was not significantly different. When comparing height, traps 1.5m above the ground captured 85% of the beetles collected but a few were caught at each height up to 15 m. Funnel trap captures exhibited a strong linear relationship (r2 = 0.79) with X. glabratus attack density and they performed well throughout the year. Catching beetles at low densities is important to port of entry monitoring programs where early detection of infestations is essential. Our trials show that multiple funnel traps baited with a single manuka oil lure were effective for capturing X. glabratus even when no infested trees were visible in the area.10aXyleborus glabratus1 aHanula, James, L.1 aUlyshen, Michael, D.1 aHorn, Scott  uhttps://weevil.myspecies.info/effect-trap-type-trap-position-time-year-and-beetle-density-captures-redbay-ambrosia-beetle-coleopte01770nas a2200157   4500008004100000020001400041245017200055210006900227260000900296300001200305490000800317520111600325653001501441100002101456856013501477       2011                        eng d  a0022-049300aEffects of Habitat Type and Trap Placement on Captures of Bark (Coleoptera: Scolytidae) and Longhorned (Coleoptera: Cerambycidae) Beetles in Semiochemical-Baited Traps0 aEffects of Habitat Type and Trap Placement on Captures of Bark C  cJune  a879-8880 v1043 aTwo studies were conducted to determine the effect of habitat selection and trap placement on catches of Scolytidae and Cerambycidae (Coleoptera) in northeastern U.S. forests. In a nonreplicated case study, four habitat types-closed canopy hardwood stand, closed canopy conifer stand, a low-intensity thinned Pinus strobus L. stand, and a high-intensity thinned P. strobus stand-were surveyed using [alpha]-pinene, ethanol, ipsenol, ipsdienol, and lanierone. Average trap catches, species richness, and the number of unique species captured were all highest in at least one of the thinned habitats. A second experiment that was replicated evaluated the placement of traps in relation to habitat patches. Semiochemical-baited traps ([alpha]-pinene and ethanol) were placed under a closed canopy forest, along an edge, and in a clearing and tested for effects on Scolytidae and Cerambycidae trap catches. Abundance and species richness were generally higher in the closed canopy and edge placements compared with traps in the open area. The highest number of unique species were captured in the edge and clearing.10aScolytinae1 aDodds, Kevin, J.  uhttps://weevil.myspecies.info/effects-habitat-type-and-trap-placement-captures-bark-coleoptera-scolytidae-and-longhorned-coleopter
