Chemical cues play a fundamental role in mate attraction and mate choice. Lepidopteran females, such as the winter moth Operophtera brumata , emit pheromones to attract males in the reproductive period. However, these chemical cues could also be eavesdropped by predators. To our knowledge, no studies have examined whether birds can detect pheromones of their prey. We performed a field experiment aimed to disentangle whether insectivorous birds can exploit the pheromones emitted by their prey for prey location. We placed artificial larvae and a dispenser on branches of Pyrenean oak trees Quercus pyrenaica. In half of the trees we placed an O.

Pheromones are chemicals capable of acting like hormones outside the body of the secreting individual, to impact the behavior of the receiving individuals. Pheromones are used from basic unicellular prokaryotes to complex multicellular eukaryotes. In addition, some vertebrates , plants and ciliates communicate by using pheromones. Lintner , Adolf Butenandt , and ethologist Karl von Frisch who called them various names, like for instance "alarm substances". Aggregation pheromones function in mate selection, overcoming host resistance by mass attack, and defense against predators. A group of individuals at one location is referred to as an aggregation, whether consisting of one sex or both sexes.

Introduction: Natural products and their odours

Laurel R. Yohe and Philipp Brand authors equally contributed to this article. All behaviors of an organism are rooted in sensory processing of signals from its environment, and natural selection shapes sensory adaptations to ensure successful detection of cues that maximize fitness. Sensory drive, or divergent selection for efficient signal transmission among heterogeneous environments, has been a useful hypothesis for describing sensory adaptations, but its current scope has primarily focused on visual and acoustic sensory modalities. Chemosensation, the most widespread sensory modality in animals that includes the senses of smell and taste, is characterized by rapid evolution and has been linked to sensory adaptations to new environments in numerous lineages. Yet, olfaction and gustation have been largely underappreciated in light of the sensory drive hypothesis.

Human behaviors are probably influenced by invisible smell signals, just like all other animals. DOI: Powerful messages can be delivered by smell, a fact known long before the means by which they did so was discovered. The ancient Greeks knew that secretions from a female dog in heat were attractive to male dogs. As two ants meet along a pheromone-marked trail, they touch antennae to sense the odorants on the other, recognizing a colony mate. In social insects, a majority of behaviors are mediated by smell signals, making them a model for pheromone research.

A review of the literature is presented that gives a background to the human sense of smell, then the importance of learnt and innate olfactory cues in animal behaviour. Some possible roles for natural products chemists interested in the interaction between animals and plants are discussed. Natural Products chemists are conspicuous when they are wandering in the bush. They habitually break pieces from plants, rub them between their fingers, and smell them. They are the people who become animated only if they detect an interesting odour; whether it be new, unusual, pleasant, or unpleasant.
