“…For ovipositing females, HIPVs can indicate lowered food quality, increased pressure from natural enemies, and risk of competition on the plant emitting HIPVs (Rasmann et al., ; Dicke & Baldwin, ; Heil & Karban, ). The presence of conspecifics is used in animal systems as an indicator of resource quality and the level of competition but also to reduce the costs of sampling by ovipositing moths (Dall et al., ; Pasqualone & Davis, ). This fact best explains our observation that more eggs, though not statistically significant, were deposited on hybrid maize exposed to C. partellus moths as opposed to non‐exposed maize plants.…”

Plants defend themselves against herbivores through activation of both constitutive and induced defences. Previous studies reported that egg deposition on maize landraces induces the release of volatiles that attract parasitoids, but little is known on the effect of these volatiles on subsequent herbivore oviposition. In addition, larval preference and development on these maize landraces is unknown. We evaluated six landraces and one hybrid maize variety for their resistance to Chilo partellus (Swinhoe) (Lepidoptera: Crambidae). Larval orientation, settling, arrest and dispersal, feeding, development, survival, and subsequent oviposition of moths were determined for individuals reared on each of these varieties under laboratory and screen house conditions. For oviposition preference studies, all treatments were initially exposed to egg deposition whereas the control treatments were not. Larval preference was generally higher for hybrid maize, compared to the landraces. Similarly, first-instar feeding on maize leaves was more intense in hybrid maize than in four of the six landraces. The amount of food consumed and assimilated by third instars over a 24-h period was, however, not different among the maize varieties. Larval survival was significantly lower in maize landraces (32%) compared to hybrid maize (54%). However, there was no difference in the larval development period between any of the treatments. Two-choice oviposition assays showed that moths preferred non-exposed maize landraces for subsequent oviposition, whereas in the hybrid, there was no difference in oviposition preference between exposed and non-exposed plants.Although the mechanism of larval suppression was beyond the scope of this study, it was inferred that the landraces showed some resistance to C. partellus feeding and that initial egg deposition on these landraces deters further colonisation by the herbivore.

“…This shows that during host plant selection, ovipositing females of S. littoralis respond specifically to volatiles with high information value and reliability for assessing plant suitability. The presence of conspecifics is used in animal systems as an indicator of resource quality and the level of competition, but also to reduce costs for sampling (Dall et al, 2005;Pasqualone and Davis, 2011). In cotton, feeding by S. littoralis larvae induces both a large quantitative increase and a qualitative change in the emission of volatiles McCall et al, 1994).…”

SUMMARYAnimals depend on reliable sensory information for accurate behavioural decisions. For herbivorous insects it is crucial to find host plants for feeding and reproduction, and these insects must be able to differentiate suitable from unsuitable plants. Volatiles are important cues for insect herbivores to assess host plant quality. It has previously been shown that female moths of the Egyptian cotton leafworm, Spodoptera littoralis (Lepidoptera: Noctuidae), avoid oviposition on damaged cotton Gossypium hirsutum, which may mediated by herbivore-induced plant volatiles (HIPVs). Among the HIPVs, some volatiles are released following any type of damage while others are synthesized de novo and released by the plants only in response to herbivore damage. In behavioural experiments we here show that oviposition by S. littoralis on undamaged cotton plants was reduced by adding volatiles collected from plants with ongoing herbivory. Gas chromatography-electroantennographic detection (GC-EAD) recordings revealed that antennae of mated S. littoralis females responded to 18 compounds from a collection of headspace volatiles of damaged cotton plants. Among these compounds, a blend of the seven de novo synthesized volatile compounds was found to reduce oviposition in S. littoralis on undamaged plants under both laboratory and ambient (field) conditions in Egypt. Volatile compounds that are not produced de novo by the plants did not affect oviposition. Our results show that ovipositing females respond specifically to the de novo synthesized volatiles released from plants under herbivore attack. We suggest that these volatiles provide reliable cues for ovipositing females to detect plants that could provide reduced quality food for their offspring and an increased risk of competition and predation.

“…Similarly, ninespined sticklebacks can monitor the foraging success of other fish through observation and subsequently select the richer of the alternative food patches, a mechanism that allows them to converge on the optimum (Coolen, Bergen, Day, & Laland, 2003;Kendal, Rendell, Pike, & Laland, 2009). Insects and birds too are known to copy the nest-site decisions of successful conspecifics and heterospecifics Pasqualone & Davis, 2011;Sarin & Dukas, 2009;Seppänen, Forsman, Mönkkönen, Krams, & Salmi, 2011). For example, less-experienced pigeons are more likely to follow more-experienced pigeons than vice versa (Flack, Pettit, Freeman, Guilford, & Biro, 2012).…”

As a form of adaptive plasticity that allows organisms to shift their phenotype toward the optimum, learning is inherently a source of developmental bias. Learning may be of particular significance to the evolutionary biology community because it allows animals to generate adaptively biased novel behavior tuned to the environment and, through social learning, to propagate behavioral traits to other individuals, also in an adaptively biased manner. We describe several types of developmental bias manifest in learning, including an adaptive bias, historical bias, origination bias, and transmission bias, stressing that these can influence evolutionary dynamics through generating nonrandom phenotypic variation and/or nonrandom environmental states. Theoretical models and empirical data have established that learning can impose direction on adaptive evolution, affect evolutionary rates (both speeding up and slowing down responses to selection under different conditions) and outcomes, influence the probability of populations reaching global optimum, and affect evolvability. Learning is characterized by highly specific, path-dependent interactions with the (social and physical) environment, often resulting in new phenotypic outcomes. Consequently, learning regularly introduces novelty into phenotype space. These considerations imply that learning may commonly generate plasticity first evolution.
