“…This confirms the findings by Carroll et al (2006, 2008), who obtained similar results for a related species, S. frugiperda , which was found to be attracted to inducible volatiles emitted from maize and cowpea seedlings. Similarly, neonate larvae of the codling moth, Cydia pomonella , are more attracted to apple fruits with other codling moth larvae than to uninfested fruits (Landolt et al, 2000). This is somewhat surprising, as these Lepidoptera are not known to aggregate, unlike many Coleoptera, for which both adults and larvae are often attracted to the volatiles of already infested plants (Crowe, 1995; Bolter et al, 1997; Müller and Hilker, 2000; Kalberer et al, 2001; Heil, 2004; Yoneya et al, 2010).…”

Plants under herbivore attack emit volatile organic compounds (VOCs) that can serve as foraging cues for natural enemies. Adult females of Lepidoptera, when foraging for host plants to deposit eggs, are commonly repelled by herbivore-induced VOCs, probably to avoid competition and natural enemies. Their larval stages, on the other hand, have been shown to be attracted to inducible VOCs. We speculate that this contradicting behavior of lepidopteran larvae is due to a need to quickly find a new suitable host plant if they have fallen to the ground. However, once they are on a plant they might avoid the sites with fresh damage to limit competition and risk of cannibalism by conspecifics, as well as exposure to natural enemies. To test this we studied the effect of herbivore-induced VOCs on the attraction of larvae of the moth Spodoptera littoralis and on their feeding behavior. The experiments further considered the importance of previous feeding experience on the responses of the larvae. It was confirmed that herbivore-induced VOCs emitted by maize plants are attractive to the larvae, but exposure to the volatiles decreased the growth rate of caterpillars at early developmental stages. Larvae that had fed on maize previously were more attracted by VOCs of induced maize than larvae that had fed on artificial diet. At relatively high concentrations synthetic green leaf volatiles, indicative of fresh damage, also negatively affected the growth rate of caterpillars, but not at low concentrations. In all cases, feeding by the later stages of the larvae was not affected by the VOCs. The results are discussed in the context of larval foraging behavior under natural conditions, where there may be a trade-off between using available host plant signals and avoiding competitors and natural enemies.

“…Attraction or orientation responses of phytophagous insects to host plant odor may be enhanced or increased with injury to the plant. The increased response of CM larvae and adults to apple fruit infested with other CM larvae has been reported ( , ). In this study, we demonstrated that crushed apple leaves with glucoimidazole retain their attractiveness to the CM adults.…”

Glycosidically bound volatiles released from apple leaf extracts (cv. Anna) were analyzed by solid-phase microextraction-gas chromatography-mass spectrometry (SPME-GC-MS) and their behavioral effects on codling moth (CM) adults were evaluated in cage bioassays. The levels of 1-octanol, linalool, geraniol, benzyl alcohol, methyl salicylate, (2R,5R)-theaspirane, and (2S,5R)-theaspirane were significantly increased in the leaf extracts containing the Aspergillus niger beta-glucosidase (BGL1) compared to the extracts containing the glucoimidazole. The attractiveness of individual compounds to CM adults was found in the following decreasing order: methyl salicylate and mixture of two theaspirane isomers, followed by linalool and benzyl alcohol. Geraniol was found to be repellent to CM adults. The addition of geraniol (39.4 ng mL(-1)) to any of the individual volatiles or to a mixture of these attractants eliminated their attractiveness. Our data suggest the possible application of geraniol as a repellent and methyl salicylate or theaspiranes as attractants for the integrated control of CM in apple orchards.

“…Attraction of early instars towards herbivore-infested plants previously has been reported for other lepidopteran species, e.g., Ostrinia furnacalis (Huang et al 2009), Spodoptera frugiperda (Carroll et al 2008), and Cydia pomonella (Landolt et al 2000). However, attraction towards HIPVs may entail risks, as herbivore-infested plants harbor competitors, and herbivory induces both direct and indirect defenses (Howe and Schaller 2008; McCormick et al 2012; Mumm and Dicke 2010).…”

“…Often, HIPVs are avoided by gravid herbivore females, which prefer to oviposit on undamaged plants, and these entail lower risks of competition for their offspring and lower amounts of herbivore-induced plant defenses (De Moraes et al 2001; Huang et al 2009; Kessler and Baldwin 2001; Rostás and Hilker 2002). However, HIPVs also can be used as cues by foraging caterpillars (Carroll et al 2008; Huang et al 2009; Landolt et al 2000), and recent reports suggest that larvae are able to infer information about plant quality and the presence of heterospecific competitors as well as the approximate density of conspecifics based on the quantity and quality of herbivore-induced volatiles (Robert et al 2012a, b). …”

Feeding Experience Affects the Behavioral Response of Polyphagous Gypsy Moth Caterpillars to Herbivore-induced Poplar Volatiles

et al. 2016

Plant volatiles influence host selection of herbivorous insects. Since volatiles often vary in space and time, herbivores (especially polyphagous ones) may be able to use these compounds as cues to track variation in host plant quality based on their innate abilities and previous experience. We investigated the behavioral response of naïve (fed on artificial diet) and experienced (fed on poplar) gypsy moth (Lymantria dispar) caterpillars, a polyphagous species, towards constitutive and herbivore-induced black poplar (Populus nigra) volatiles at different stages of herbivore attack. In Y-tube olfactometer assays, both naïve and experienced caterpillars were attracted to constitutive volatiles and volatiles released after short-term herbivory (up to 6 hr). Naïve caterpillars also were attracted to volatiles released after longer-term herbivory (24–30 hr), but experienced caterpillars preferred the odor of undamaged foliage. A multivariate statistical analysis comparing the volatile emission of undamaged plants vs. plants after short and longer-term herbivory, suggested various compounds as being responsible for distinguishing between the odors of these plants. Ten compounds were selected for individual testing of caterpillar behavioral responses in a four-arm olfactometer. Naïve caterpillars spent more time in arms containing (Z)-3-hexenol and (Z)-3-hexenyl acetate than in solvent permeated arms, while avoiding benzyl cyanide and salicyl aldehyde. Experienced caterpillars avoided benzyl cyanide and preferred (Z)-3-hexenyl acetate and the homoterpene (E)-4,8-dimethyl-1,3,7-nonatriene (DMNT) over solvent. Only responses to DMNT were significantly different when comparing experienced and naïve caterpillars. The results show that gypsy moth caterpillars display an innate behavioral response towards constitutive and herbivore-induced plant volatiles, but also that larval behavior is plastic and can be modulated by previous feeding experience.Electronic supplementary materialThe online version of this article (doi:10.1007/s10886-016-0698-7) contains supplementary material, which is available to authorized users.
