“…The retinal sensitivity of A. planipennis to the 430-nm region of the spectrum may explain why purple (dark) control traps (430-nm main peak) are attractive to both sexes of A. planipennis (Francese et al 2005(Francese et al , 2008Crook et al 2008a). However, it is difÞcult to explain the biological signiÞcance of the attraction of A. planipennis to purple.…”

“…Unless speciÞed, colors were produced using Sherwin Williams (SW) Company (Richardson, TX) stock colors: light purple (SW6554, Lite Lavender), dark purple (SW6983, Fully Purple), light green (SW6920, Center Stage Green), dark green (Benjamin Moore ÔColor PreviewÕ 2036-20, Irish Moss; Benjamin Moore & Co., Montvale, NJ), light blue (SW6806, Rhythmic Blue), dark blue (SW6967, Frank Blue), and red (9963828, Ruby Red; Ace Hardware, Oak Brook, IL). Purple corrugated plastic (Coroplast Inc., Dallas TX), found to be attractive to A. planipennis in previous studies by Francese et al (2005Francese et al ( , 2008 and Crook et al (2008a) were used as a control treatment in both assays.…”

“…Oliver et al (2002) found that buprestids of several genera (including Agrilus) showed a preference for colors in the violet range (400 Ð 430 nm). In addition to this, Oliver et al (2004) and Francese et al (2005Francese et al ( , 2008 found that purple-violet colored traps with large silhouettes were most attractive to adult A. planipennis. Purple plastic sticky panel traps have since been used for A. planipennis trap placement studies (Francese et al 2008).…”

“…Detection of A. planipennis at low densities by tree inspection has been ineffective because external symptoms of damage such as crown dieback, bark splits, epicormic branching, and exit holes (throughout the tree surface) are not apparent until heavy infestation has already taken place (Cappaert et al 2005, Francese et al 2005. A. planipennis are attracted to ash trees that have been stressed by girdling or herbicide treatments (Poland et al 2004).…”

Retinal sensitivity of Agrilus planipennis Fairmaire (Coleoptera: Buprestidae) was examined with an aim to improve trap efficacy for the beetle. Electroretinogram (ERG) recordings from dark-adapted compound eyes of male and female were measured at different wavelengths across the spectrum ranging from 300 to 700 nm. The spectral sensitivity curves revealed peaks in the UV (340 nm), the violet/purple (420-430 nm), blue (460 nm), and green (540-560 nm) regions of the spectrum. Females were sensitive to red regions of the spectrum (640-670 nm), whereas males were not. A spectrophotometer was used to measure the wavelength and reflectance for ash foliage, purple corrugated plastic traps, as well as the elytra and abdomen of adult A. planipennis. Traps were painted using colors based on ERG and spectrophotometer measurements and compared with purple corrugated plastic traps currently used by the USDA-APHIS-PPQ-EAB National Survey. In a field assay conducted along the edges of several A. planipennis-infested ash stands, there were no significant differences in trap catch among green, red, or purple treatments. Dark blue traps caught significantly fewer A. planipennis than red, light green, or dark purple traps. In a second assay where purple and green treatments were placed in the mid canopy of ash trees (approximately 13 m in height), trap catch was significantly higher on green treatments. We hypothesize that when placed in the mid-canopy, green traps constitute a foliage-type stimulus that elicits food-seeking and/or host seeking behavior by A. planipennis.

“…Research on EAB also has demonstrated short-range responses to visual cues (Domingue and Baker 2012;Francese et al 2005;Lelito et al 2007Lelito et al , 2008 and contact pheromones (Lelito et al 2009;Silk et al 2009). Initial research suggested the absence of long-range, volatile pheromones with EAB (Rodriguez-Saona et al 2006).…”

A Biologically Active Analog of the Sex Pheromone of the Emerald Ash Borer, Agrilus planipennis

The emerald ash borer, Agrilus planipennis (Coleoptera: Buprestidae) (EAB), is an invasive species causing unprecedented levels of mortality to ash trees in its introduced range. The female-produced sex pheromone of EAB has been shown to contain the macrocyclic lactone (3Z)-dodecen-12-olide. This compound and its geometrical isomer, (3E)-dodecen-12-olide, have been demonstrated previously to be EAG active and, in combination with a host-derived green leaf volatile, (3Z)-hexenol, to be attractive to male EAB in green prism traps deployed in the ash tree canopy. In the current study, we show that the saturated analog, dodecan-12-olide, is similarly active, eliciting an antennal response and significant attraction of EAB in both olfactometer and trapping bioassays in green traps with (3Z)-hexenol. Conformational modeling of the three lactones reveals that their energies and shapes are very similar, suggesting they might share a common receptor in EAB antennae. These findings provide new insight into the pheromone ecology of this species, highlighting the apparent plasticity in response of adults to the pheromone and its analog. Both of the unsaturated isomers are costly to synthesize, involving multistep, low-yielding processes. The saturated analog can be made cheaply, in high yield, and on large scale via Mitsunobu esterification of a saturated ω-hydroxy acid or more simply by Baeyer-Villiger oxidation of commercially available cyclododecanone. The analog can thus provide an inexpensive option as a lure for detection surveys as well as for possible mitigation purposes, such as mating disruption.

Analyses of the elytral hydrocarbons from male and female emerald ash borer, Agrilus planipennis Fairmaire, that were freshly emerged vs. sexually mature (>10 days old) revealed a female-specific compound, 9-methyl-pentacosane (9-Me-C(25)), only present in sexually mature females. This material was synthesized by the Wittig reaction of 2-decanone with (n-hexadecyl)-triphenylphosphonium bromide followed by catalytic reduction to yield racemic 9-Me C(25), which matched the natural compound by gas chromatography/mass spectrometry (retention time and EI mass spectrum). In field bioassays with freeze-killed sexually mature A. planipennis females, feral males spent significantly more time in contact and attempting copulation with unwashed females than with females that had been washed in n-hexane to remove the cuticular lipids. Hexane-washed females to which 9-Me-C(25) had been reapplied elicited similar contact time and percentage of time attempting copulation as unwashed females, indicating that 9-methyl-pentacosane is a contact sex pheromone component of A. planipennis. This is the first contact sex pheromone identified in the Buprestidae.
