As part of research to identify host-based attractants for X. glabratus, we discovered that a diverse array of non-target ambrosia beetles was attracted to the same substrates as X. glabratus. During Sep-Dec 2009, several field tests were conducted in north Florida (in woodlands with advanced stages of laurel wilt) with traps baited with commercial lures of the essential oils, manuka and phoebe, and with freshly-cut wood bolts of avocado (a known host) and lychee (Litchi chinensis, a non-host high in the sesquiterpene [alpha]-copaene, a putative host attractant). In addition, manuka-baited traps were deployed in avocado groves in south Florida to monitor for potential spread of X. glabratus. The combined trapping results indicated that none of these substrates was specific in attraction of X. glabratus. Numerous non-target ambrosia beetles were captured, including 17 species representative of 4 tribes within the subfamily Scolytinae. This report provides photo-documentation and data on the species diversity and relative abundance for a group of poorly-studied beetles, the scolytine community in Florida Persea habitats.10aXyleborus glabratus1 aKendra, Paul, E.1 aSanchez, Jorge, S.1 aMontgomery, Wayne, S.1 aOkins, Katherine, E.1 aNiogret, Jerome1 aPena, Jorge, E.1 aEpsky, Nancy, D.1 aHeath, Robert, R.  uhttps://weevil.myspecies.info/diversity-scolytinae-coleoptera-curculionidae-attracted-avocado-lychee-and-essential-oil-lures01283nas a2200217   4500008004100000020001400041245011900055210006900174260000900243300001200252490000700264520050300271653002400774100002100798700002600819700002300845700002100868700002000889700002100909856013500930       2012                        eng d  a0015-404000aMETHOD FOR COLLECTION OF LIVE REDBAY AMBROSIA BEETLES, XYLEBORUS GLABRATUS (COLEOPTERA: CURCULIONIDAE: SCOLYTINAE)0 aMETHOD FOR COLLECTION OF LIVE REDBAY AMBROSIA BEETLES XYLEBORUS   cJune  a513-5160 v953 aDevelopment of improved lures for Xyleborus glabratus will be expedited through experimental research conducted with host-seeking females. As an alternative to laboratory rearing of X. glabratus, we developed a simple method for field collection of dispersing females using freshly-cut host wood as bait. Female X. glabratus collected with this method are behaviorally and physiologically in host-seeking mode, ideally suited for evaluation of host-based attractants in controlled laboratory tests.10aXyleborus glabratus1 aKendra, Paul, E.1 aMontgomery, Wayne, S.1 aSanchez, Jorge, S.1 aDeyrup, Mark, A.1 aNiogret, Jerome1 aEpsky, Nancy, D.  uhttps://weevil.myspecies.info/method-collection-live-redbay-ambrosia-beetles-xyleborus-glabratus-coleoptera-curculionidae-scolytin02669nas a2200253   4500008004100000020001400041245017300055210006900228260000800297300001200305490000800317520173100325653002402056100002102080700002002101700002602121700002302147700002102170700002402191700002202215700002102237700002202258856013502280       2012                        eng d  a0022-049300aTemporal Analysis of Sesquiterpene Emissions From Manuka and Phoebe Oil Lures and Efficacy for Attraction of Xyleborus glabratus (Coleoptera: Curculionidae: Scolytinae)0 aTemporal Analysis of Sesquiterpene Emissions From Manuka and Pho  cApr  a659-6690 v1053 aRedbay ambrosia beetle, Xyleborus glabratus Eichhoff, is an exotic wood-borer that vectors the fungal agent (Raffaelea lauricola) responsible for laurel wilt. Laurel wilt has had severe impact on forest ecosystems in the southeastern United States, killing a large proportion of native Persea trees, particularly redbay (P. borbonia) and swampbay (P. palustris), and currently poses an economic threat to avocado (P. americana) in Florida. To control the spread of this lethal disease, effective attractants are needed for early detection of the vector. Two 12-wk field tests were conducted in Florida to evaluate efficacy and longevity of manuka and phoebe oil lures, and to relate captures of X. glabratus to release rates of putative sesquiterpene attractants. Two trap types were also evaluated, Lindgren funnel traps and sticky panel traps. To document lure emissions over time, a separate set of lures was aged outdoors for 12 wk and sampled periodically to quantify volatile sesquiterpenes using super-Q adsorbant and gas chromatography-mass spectroscopy analysis. Phoebe lures captured significantly more X. glabratus than manuka lures, and sticky traps captured more beetles than funnel traps. Phoebe lures captured X. glabratus for 10-12 wk, but field life of manuka lures was 2-3 wk. Emissions of [alpha]-copaene, [alpha]-humulene, and cadinene were consistently higher from phoebe lures, particularly during the 2-3 wk window when manuka lures lost efficacy, suggesting that these sesquiterpenes are primary kairomones used by host-seeking females. Results indicate that the current monitoring system is suboptimal for early detection of X. glabratus because of rapid depletion of sesquiterpenes from manuka lures.10aXyleborus glabratus1 aKendra, Paul, E.1 aNiogret, Jerome1 aMontgomery, Wayne, S.1 aSanchez, Jorge, S.1 aDeyrup, Mark, A.1 aPruett, Grechen, E.1 aPloetz, Randy, C.1 aEpsky, Nancy, D.1 aHeath, Robert, R.  uhttps://weevil.myspecies.info/temporal-analysis-sesquiterpene-emissions-manuka-and-phoebe-oil-lures-and-efficacy-attraction-xylebo
