“…2016; Giacomuzzi et al . 2016, 2017b) suggests that the headspace volatiles described for the various caterpillar species do little to explain these results. 2-phenylethanol is no more prevalent in volatiles induced by species that respond strongly to it ( Pandemis and C. rosaceana ) than it is in the volatiles induced by S. ocellana .…”

Abstract-Pandemis limitata (Robinson) (Lepidoptera: Tortricidae) is one of several leaf-feeding caterpillar pests of commercial tree-fruit crops in British Columbia, Canada. Recent discovery that European Pandemis Hübner species are attracted by lures combining acetic acid and the caterpillar-induced apple-leaf volatiles, 2-phenylethanol, and phenylacetonitrile, prompted our examination of P. limitata response to these compounds. Trapping tests in organic apple orchards revealed that neither of these individual benzenoids, nor their binary combination, was attractive. Acetic acid alone was weakly attractive, but more importantly, catches increased significantly when an acetic-acid co-lure was combined with 2-phenylethanol or phenylacetonitrile, individually and together. Catches of male and female P. limitata with acetic acid + 2-phenylethanol, or acetic acid + 2-phenylethanol + phenylacetonitrile were similar, respectively, and both sexes were caught significantly less often in traps baited with acetic acid + phenylacetonitrile. When combined with acetic-acid co-lures, traps baited with membrane dispensers releasing 2-phenylethanol at~1 mg/day caught significantly more moths than traps baited with rubber septa lures releasing 2-phenylethanol at~0.6 mg/day. Moth catches in traps baited with 2-phenylethanol were unaffected when the emission of acetic-acid co-lures was increased from~28 to 63 mg/day. Catches of male P. limitata in traps baited with sex pheromone were significantly greater than catches in traps baited with acetic acid + 2-phenylethanol, or traps baited with a ternary blend of acetic acid + 2-phenylethanol + sex pheromone. Catches of female P. limitata in traps baited with acetic acid + 2-phenylethanol were significantly reduced when it was combined with sex pheromone. Use of the ternary acetic acid + 2-phenylethanol + phenylacetonitrile blend provides an opportunity to develop multispecies bisexual trapping systems to improve management of sympatric tortricid pests currently causing economic losses in organic apples in British Columbia. More work on long-lasting release devices, nonsaturating traps, and organically acceptable killing agents are needed to develop organic mass-trapping systems.

Specificity of Herbivore Defense Responses in a Woody Plant, Black Poplar (Populus nigra)

2019

The specificity of woody plant defense responses to different attacking herbivores is poorly known. We investigated the responses of black poplar ( Populus nigra ) to leaf feeding by three lepidopteran species ( Lymantria dispar, Laothoe populi and Amata mogadorensis ) and two leaf beetle species ( Phratora vulgatissima and Chrysomela populi ). Of the direct defenses monitored, increases in trypsin protease inhibitor activity and the salicinoid salicin were triggered by herbivore damage, but this was not herbivore-specific. Moreover, the majority of leaf salicinoid content was present constitutively and not induced by herbivory. On the other hand, volatile emission profiles did vary among herbivore species, especially between coleopterans and lepidopterans. Monoterpenes and sesquiterpenes were induced in damaged and adjacent undamaged leaves, while the emission of green leaf volatiles, aromatic and nitrogen-containing compounds (known to attract herbivore enemies) was restricted to damaged leaves. In conclusion, indirect defenses appear to show more specific responses to attacking herbivores than direct defenses in this woody plant.

“…An increasing body of research has developed bisexual attractants for key tortricid pests of apple Malus domestica Borkhausen, using host plant volatiles and/or microbial‐based compounds (codling moth: Light et al., ; Landolt, Suckling, & Judd, ; Landolt et al., ; leaf rollers: Giacomuzzi et al., ; Giacomuzzi, Mattheis, Basoalto, Angeli, & Knight, ; Judd, Knight, & El‐Sayed, 2017a, 2017b; Basoalto et al., ; oriental fruit moth: Mujica et al., ). The ability of pest managers to monitor female moth populations can increase the precision in tracking the pest phenology and improve timing of control tactics (Knight & Light, 2005a).…”

Studies compared moth captures of three pests (Lepidoptera: Tortricidae) of apple, Malus domestica Borkhausen, in delta traps using removable liners coated with either a sticky gel (SG) or a hot‐melt pressure sensitive (HMPS) adhesive. Laboratory and field studies with Cydia pomonella (L.), Choristoneura rosaceana (Harris) and Grapholita molesta (Busck) demonstrated that traps with either liner, baited with a pair of virgin females catch males, but at significantly different levels. In the field, male moth captures in traps with the HMPS liner were significantly greater than in traps with the SG liner for C. rosaceana, and G. molesta; but not for C. pomonella. Similar results were observed in laboratory studies using flight tunnels. Additional studies demonstrated that this difference in moth captures between liners was not due to levels of female mortality, but instead was correlated with the occurrence of the female's ventral abdominal surface becoming stuck in the adhesive. Studies showed that a significantly greater proportion of females of all species had their ventral abdomen stuck in the SG than HPMS adhesive on day 1, but only G. molesta and C. rosaceana on day 3. In addition, the tackiness of the two adhesives affected moth movement on the liner with males and females of all species moving farther on liners with SG than HMPS adhesive. A greater proportion of female G. molesta and C. pomonella were either stuck supined or laterally on the SG than HMPS adhesive, and females in this position captured as many males as when prone and unstuck on the liner. Our studies demonstrate that adhesives can secondarily influence male moth captures on trap liners when used with bisexual attractants, and that adhesive type should be considered when developing action thresholds.

Survey of conspecific herbivore‐induced volatiles from apple as possible attractants for Pandemis pyrusana (Lepidoptera: Tortricidae)

Abstract: These data show that herbivore injury does not create a unique chemical signal for adults to locate oviposition or rendezvous sites. Instead, moths may cue to the aromatic-acetic acid combination as a nutritional cue to locate sugary resources. © 2017 Society of Chemical Industry.
