Abstract

Redbay ambrosia beetle, Xyleborus glabratus, is native to Southeast Asia, but subsequent to introduction in Georgia in 2002, it has become a serious invasive pest in the USA, now established in nine southeastern states. Females vector Raffaelea lauricola, the fungus that causes laurel wilt, a lethal vascular disease of trees in the family Lauraceae. Laurel wilt has caused extensive mortality in native Persea species, including redbay (P. borbonia), swampbay (P. palustris), and silkbay (P. humilis). Avocado (P. americana) is now impacted in Florida, and with continued spread, laurel wilt has potential to affect avocado and native Lauraceae in California, Mexico, and throughout the American tropics. Effective lures for detection and control of X. glabratus are critical to slow the spread of laurel wilt. No pheromones are known for this species; primary attractants are volatile terpenoids emitted from host Lauraceae. This report provides a concise summary of the chemical ecology of X. glabratus, highlighting research to identify kairomones used by females for host location. It summarizes development of essential oil lures for pest detection, including discussions of the initial use of phoebe and manuka oil lures, the current cubeb oil lure, and a newly-developed distilled oil lure enriched in (-)-α-copaene.

1 Introduction

The redbay ambrosia beetle, Xyleborus glabratus Eichhoff (Coleoptera: Curculionidae: Scolytinae), is a wood-borer endemic to Southeast Asia. Although benign in its native range [1], the beetle has become a serious invasive pest of agricultural and forest ecosystems in the USA. Xyleborus glabratus females are the primary vectors of a fungal pathogen that causes laurel wilt, a lethal vascular disease of American trees in the family Lauraceae [2,3]. During gallery excavation, beetles introduce spores of several symbiotic fungi, including Raffaelealauricola T. C. Harr., Fraedrich & Aghayeva, the etiologic agent of laurel wilt [4,5]. Presence of R. lauricola in susceptible hosts triggers secretion of gels and formation of parenchymal tyloses within xylem vessels [6,7]. This defensive response impedes water transport, which leads to systemic wilt and ultimately death of infected trees.

First detected in the USA during 2002 near Savannah, Georgia, X. glabratus has since invaded eight additional southeastern states [8], where incidence of laurel wilt has escalated to epidemic proportions (reviewed in [9,10,11]). Ecological impact has been most severe on native Persea populations, with extensive mortality of redbay[P. borbonia(L.) Spreng.], swampbay [P. palustris (Raf.) Sarg.], and silkbay (P. humilis Nash). Currently, commercial avocado (P. americana Mill.) is impacted in southern Florida [7,12], and with continued spread, laurel wilt may threaten avocado production in Mexico and California. In addition, numerous trees and woody shrubs within the Lauraceae are potentially at risk in the USA, Mexico, and throughout the American tropics. An effective lure for early detection of X. glabratus is critical for development of management programs to slow the spread of laurel wilt.

2 Chemical Ecology of X. glabratus

Like other ambrosia beetles within the tribe Xyleborini, X. glabratus is known to have extensive inbreeding, haplodiploid sex determination, and a sex ratio highly skewed toward females [13]. Pheromones are not used by these species, since females typically mate with their flightless male siblings before dispersing from natal trees. However, females of X. glabratus are atypical with respect to their host-seeking behaviors. The majority of xyleborine beetles are broad generalists that target stress-weakened or dying trees [14], but X. glabratus can function ecologically as a primary colonizer, attacking live healthy trees [2]. Xyleborus glabratus is not attracted to ethanol [3,15], a volatile indicative of tree decay, which is the standard lure used for general detection and monitoring of ambrosia beetles [16]. Furthermore, X. glabratus is not a host generalist in the USA, but appears to be restricted to members of the Lauraceae [10,17].

Given the absence of species-specific pheromones for X. glabratus, and lack of attraction to ethanol, research on lure development has focused on the kairomones used by X. glabratus for host location. The current hypothesis is that dispersing females detect, via antennal olfactory receptors, a mixture of volatile terpenoids characteristic of the Lauraceae (i.e., a signature host bouquet) [18,19,20,21,22,23]. A comprehensive comparative study [17] examined nine species within the Lauraceae (including avocado cultivars representative of each of the three botanical races) to determine in-flight attraction of X. glabratus as related to phytochemical emissions from host wood. Emissions of α-copaene, α-cubebene, α-humulene, and calamenene (all sesquiterpene hydrocarbons) were positively correlated with attraction to Lauraceae [17]. Of these compounds, α-copaene and α-humulene had been correlated previously with attraction to essential oil lures and to wood from lychee (Litchi chinensis Sonn.; Sapindaceae) [19]. Lychee is not a host of X. glabratus, but particular cultivars are highly attractive to females due to sesquiterpene emissions similar to those of the Lauraceae [19,22,24]. In addition, independent research identified eucalyptol (1,8 cineole; a monoterpene ether) as another host-based attractant [25]. For all these terpenoid compounds, olfactory chemoreception has been confirmed in female X. glabratus using dissected antennae and electrophysiological recording techniques [17,26].

3 Field Lures

Although identification of specific attractant chemicals has been useful for understanding the chemical ecology and host-seeking behaviors of X. glabratus, production of field lures using synthetic sesquiterpenes may not be feasible. Many sesquiterpenes, particularly α-copaene, are expensive, difficult to synthesize, and not readily available in quantities sufficient for trap deployment [27]. Consequently, development of economical lures has relied on the use of plant-derived essential oils naturally high in attractive sesquiterpenes.

3.1 Manuka and Phoebe Oils

Research by Crook et al. [28] on host-based semiochemicals for the emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), identified two essential oils attractive to this wood-boring beetle: manuka oil (extracted from Leptospermum scoparium Forst. & Forst.; Myrtaceae) and phoebe oil (from Phoebe porosa Mez; Lauraceae). When initially tested in Georgia and South Carolina, these two oils were also found to be attractive baits for trapping X. glabratus [18]. However, when commercial manuka and phoebe oil lures were evaluated in Florida in 2009-2010, both were found to be fairly non-specific, capturing a variety of non-target Scolytinae [21,24]. More importantly, the manuka oil lures were not competitive with host Persea wood (Figure 1A), which had higher content of α-copaene and other sesquiterpene constituents [19]. In addition, manuka oil lures had a field life of only 2-3 weeks (Figure 1C) due to rapid (exponential) loss of sesquiterpenes when exposed to field conditions [21]. In contrast, phoebe oil lures had substantially higher content of α-copaene [19], were competitive with host wood (Figure 1A), captured significantly more X. glabratus than manuka oil lures (Figure 1B), and despite rapid loss of terpenoids initially, continued to release low levels of attractive sesquiterpenes for at least 10 weeks (Figure 1C). Unfortunately, shortly after completion of the field studies by Kendra et al. [21], phoebe oil lures could no longer be produced commercially due to a limited supply of source trees in Brazil. Therefore, the suboptimal manuka oil lure became the standard for detection of X. glabratus in the USA.

3.2 Cubeb Oil

The shortcomings of manuka oil lures prompted research to evaluate other essential oils as potential alternatives. Initial field tests in 2012 compared captures of X. glabratus among seven essential oils, including manuka and phoebe oils [9,15]. Five new oils – cubeb, ginger root, angelica seed, tea tree, and Valencia orange oils – were chosen based on (i) their sesquiterpene content, which included constituents that were correlated with captures of X. glabratus in previous tests [19,21], and (ii) their attractiveness to males of the Mediterranean fruit fly, Ceratitis capitata Wied. (Diptera: Tephritidae), another pest attracted to substrates high in α-copaene [27,29]. Of the new oils evaluated, ginger root and angelica seed oils were moderately attractive, but whole cubeb oil (obtained from berries of tailed pepper, Piper cubeba L.; Piperaceae) was identified as a strong new attractant for female X. glabratus (Figure 2) [9].

Treatments consisted of manuka (Man), cubeb (Cub), phoebe (Phb), ginger root (Gin), angelica seed (Ang), tea tree (Tea), Valencia orange (Ora) oils, and an unbaited control trap (Ctrl); N = 5 traps per treatment. A membrane-based dispenser was used to prepare the lures, and each lure was loaded with 5 ml of neat oil. Bars topped with the same letter are not significantly different; adapted from [9].

Subsequent studies in 2013 with a commercial cubeb lure (proprietary plastic bubble containing a distilled oil product enriched in sesquiterpenes; Synergy Semiochemicals Corp., Burnaby, BC, Canada) found that this product captured significantly more X. glabratus than the commercial manuka oil lure in field trials [15,30]. Further evaluations [31] indicated that the cubeb oil lure was also better than the phoebe oil lure (Figure 3A) and had a field life of at least 12 weeks (Figure 3B).

Temporal analysis of cubeb lure emissions revealed that its superior longevity was due to extended low release of sesquiterpenes, primarily α-copaene (Figure 4A) and α-cubebene (Figure 4B) [31]. The bubble dispenser used for the new cubeb lure has a much lower surface area-to-volume ratio than the flat rectangular design of the manuka oil lure. This difference, coupled with a thicker release membrane, has resulted in a better delivery system for sustained release of sesquiterpene attractants.

Inset enhances the scale for emissions beginning at 4 wk, the point at which manuka lures lost efficacy for attraction of X. glabratus in field tests. Volatiles were isolated by super-Q collection, analyzed by GC-MS, and identified by comparison of Kovats retention index with synthetic chemical; adapted from [31].

3.3 Copaiba Oil and Enriched α-Copaene Oil

With acceptance of the cubeb oil lure as the new standard for detection of X. glabratus, research (in collaboration with Synergy Semiochemicals Corp.) focused on elucidation of the attractive components found in cubeb oil. Since this essential oil is composed of a complex mixture of terpenoids, hydrodistillation was used to separate whole cubeb oil into multiple fractions, based on boiling point of the terpenoid constituents. These fractions were then evaluated in electroantennographic analyses and binary-choice bioassays to quantify olfactory and behavioral responses, respectively. Results indicated that fractions with high α-copaene and α-cubebene content were the most bioactive for female X. glabratus [32], supporting previous hypotheses regarding the importance of these kairomones [15,17,18,19,20,21,22,23,31]. Based on this observation, two additional essential oil products were evaluated, both formulated in slow-release bubble dispensers. The first lure contained whole copaiba oil (extracted from species of Copaifera L.; Leguminoseae), an essential oil lacking in α-cubebene, but with twice as much α-copaene as whole cubeb oil [32]. In two field trials, the prototype copaiba oil lure captured equal numbers of X. glabratus as the commercial cubeb oil lure (Figure 5A) [32].

The second prototype lure contained a proprietary essential oil product that was distilled to achieve 50 percent α-copaene content. In multiple field tests, this enriched α-copaene lure captured significantly more X. glabratus than the cubeb oil lure (Figure 5A), and also displayed field longevity of at least three months (Figure 5B) [32,33]. This research confirmed the role of α-copaene as a primary host-location cue, and identified the 50% α-copaene lure (now available commercially) as an improved tool for more sensitive detection of X. glabratus than that currently provided by the cubeb oil lure. In addition, recent research [34] documented that the enriched α-copaene lure is also attractive to Euwallacea nr. fornicatus, an invasive ambrosia beetle that vectors the fungus responsible for Fusarium dieback disease in avocado and numerous other trees in the USA [35,36,37].

3.4 Chemical Analysis of the Enriched α-Copaene Oil

We previously identified the chemical composition of the commercial α-copaene lure by GC-FID and GC-MS using an apolar column, DB-5MS [38]. Lure constituents were almost entirely sesquiterpene hydrocarbons (~98.7%), with only one oxygenated sesquiterpene, caryophyllene oxide (~1.3%). The predominant components were α-copaene (~51.3%), β-caryophyllene (~22.5%), δ-cadinene (~10%) and α-humulene (~4.2%); minor components included α-cubebene, β-cubebene, β-elemene, alloaromadendrene, γ-muurolene and α-muurolene. We also conducted chiral separation of the α-copaene component, using an Rt-βDexse column [38]. This separation indicated that the lure contained (+)-α-copaene (0.1%) and (-)-α-copaene (99.9%). In nature, (-)-α-copaene occurs as the more prevalent enantiomer [39,40] and our results were in good agreement. Enantiomers often show different pharmacological and biological activity, underlying the importance of accurate separation and identification. Our analysis of the lure contents indicated that X. glabratus is preferentially attracted to (-)-α-copaene [38], whereas C. capitata is more responsive to the positive enantiomer [27]. Development of effective enantiomeric analysis methods can help not only in understanding the biological functions, but also in exploring new applications.

4 Conclusions

Research over the past few years has been successful in terms of (i) gaining a better understanding of the semiochemicals used by female X. glabratus for host location, and (ii) improving the efficacy and field longevity of host-based lures for detection of this pest. However, host location and acceptance by an ambrosia beetle is a multi-step process that requires perception and interpretation of a series of cues presented in proper sequence and in proper context [17]. Host volatile terpenoids are chemical cues that direct only the initial steps of that process. Further improvement of pest detection systems for X. glabratus should be possible through novel combinations of appropriate attractant cues. Experimental research is just beginning to evaluate multi-component lures composed of several known ambrosia beetle attractants. The essential oil enriched in the negative enantiomer of α-copaene is the best single lure identified to date for dispersing X. glabratus, but efficacy of this kairomone-based lure may be increased when coupled with food-based fungal odors [41,42] or with volatile spiroketals (e.g. conophthorin, chalcogran [43,44,45]). In conjunction with lure evaluations, research is needed for improvement of trap design. With essential oil lures alone, capture efficiency of X. glabratus is low with our current detection systems [21,31,32]; this may be increased with appropriate visual cues, including optimization of trap color, shape and diameter [46], and potentially with incorporation of light emitting diodes of specific wavelengths [45].
