“…Because it allows a good control over the stimuli and the experience of the tested animal, PER conditioning was used to ask which features honeybees learn within a complex floral mixture. Bees were thus conditioned with floral extracts Pham-Delègue et al 1997;Wright et al 2002) or with synthetic mixtures containing 6 -14 components (Pham-Delègue et al 1993;Wadhams et al 1994;Blight et al 1997;Reinhard et al 2010). A general finding of these experiments is that when bees learn a mixture and are afterward tested with the individual components, they respond most to only some of the mixture's components.…”

“…A general finding of these experiments is that when bees learn a mixture and are afterward tested with the individual components, they respond most to only some of the mixture's components. Such components have been coined key-compounds (Pham-Delègue et al 1993;Blight et al 1997). To test bees' responses to all the components of a complex mixture, an elegant approach consisted of coupling chemical analysis techniques with PER conditioning (Wadhams et al 1994;Le Métayer et al 1997).…”

The honeybee Apis mellifera has emerged as a robust and influential model for the study of classical conditioning, thanks to the existence of a powerful Pavlovian conditioning protocol, the olfactory conditioning of the proboscis extension response (PER). In 2011, the olfactory PER conditioning protocol celebrates 50 years since it was first introduced by Kimihisa Takeda in 1961. Here, we review its origins, developments, and perspectives in order to define future research avenues and necessary methodological and conceptual evolutions. We show that olfactory PER conditioning has become a versatile tool for the study of questions in extremely diverse fields in addition to the study of learning and memory and that it has allowed behavioral characterizations, not only of honeybees, but also of other insect species, for which the protocol was adapted. We celebrate, therefore, Takeda's original work and prompt colleagues to conceive and establish further robust behavioral tools for an accurate characterization of insect learning and memory at multiple levels of analysis.Classical conditioning (Pavlov 1927) is a form of conditioning in which a subject learns to associate a neutral stimulus (the "conditioned stimulus," or CS), which does not originally elicit a behavioral response, with a stimulus of biological significance (the "unconditioned stimulus," or US), which elicits an innate, often reflexive, response. Through this association, the originally neutral stimulus acquires the capacity to elicit a conditioned response.Decades of research on animal learning and memory have established some invertebrates (e.g., the sea hare, Aplysia californica, the fruit fly, Drosophila melanogaster, the honeybee, Apis mellifera) as standard models for the study of classical conditioning (Giurfa 2007b;Menzel et al. 2007). This success can be attributed to the fact that these animals can learn nonassociative as well as Pavlovian and operant associations and possess relatively simple nervous systems that allow retracing of these phenomena to the cellular and molecular levels in different kinds of laboratory preparations. Among these invertebrates, the honeybee, Apis mellifera, has emerged as a robust and influential model for the study of

“…In this paper, we report consequences of odor learning in a situation where this parasitoid has a choice between the learned odor and an alternative one. We also consider the influence of odor concentration, which is an important factor in odor learning by the honeybee (see, e.g., Marfaing, Rouault, & Laffort, 1989;Pham-Delegue et al, 1993;Vareschi, 1971 in 5% bleach, and rinsed in water before storage in tubes containing agar-agar and some honey, at 25°C and on a 12:12-h light dark (LD) cycle. Thus the insects were not exposed to odors from their development medium during pupal and adult stages.…”

This paper deals with the effect of associative and nonassociative odor conditioning on odor preference in a specialist larval parasitic wasp of Drosophila melanogaster, Leptopilina boulardi. Differently experienced females were offered a choice between banana and strawberry odors in a fourarmed olfactometer. Wasps that were allowed to oviposit in an odorless airflow before testing exhibited no significant response to the odors, whereas females with an oviposition experience in the presence of an odor clearly preferred the scent that they had experienced. Furthermore, exposure to strawberry odor after oviposition could also induce a preference for strawberry or banana odor, depending on the concentrations of both scents used for conditioning and testing. This effect was independent of the time elapsed between oviposition and strawberry exposure, suggesting that it was caused by nonassociative conditioning and not by backward associative learning. Exposure to banana odor after oviposition had no effect on females' responses. Variations in odor concentrations also influenced the expression of associative learning, although to a much lesser extent.

“…Floral scent bouquets often are complex mixtures of volatile organic compounds (Knudsen & Gershenzon 2006), in which either several compounds within bouquets jointly serve as attractants or repellents (Bruce, Wadhams & Woodcock 2005;Schiestl, Huber & Gomez 2011), or individual compounds are responsible for these functions (Pham-Delegue et al 1993;Cunningham et al 2004;Wright & Smith 2004;Riffell et al 2009). Modifications such as the addition of a single volatile to floral bouquets can add novel functions to it, for example changing the attractive or repellent character of floral scent bouquets (Shuttleworth & Johnson 2010;Junker, Gershenzon & Unsicker 2011;Bischoff et al 2015).…”

Summary 1.A common structural feature of natural communities is the non-random distribution of pairwise interactions between organisms of different trophic levels. For plant-animal interactions, it is predicted that both stochastic processes and functional plant traits that facilitate or prevent interactions are responsible for these patterns. 2. However, unbiased manipulative field experiments that rigorously test the effects of individual traits on community structure are lacking. We address this gap by manipulating floral scent bouquets in the field. 3. Manipulation of floral scent bouquets led to quantitative as well as qualitative restructuring of flower-visitor networks, making them more generalized. Olfactometer trials confirmed both positive and negative responses to scent bouquets. 4. Our results clearly show that the distribution of insect visitors to the two abundant study plant species reflects the insects' species-specific preferences for floral scents, rather than for visual or morphological floral traits. 5. Thus, floral scents may be of major importance in partitioning flower-visitor interactions. Integrating experimental manipulations of plant traits with field observations of interaction patterns thus represents a promising approach for revealing the processes that structure species assemblages in natural communities.
