Research in Semiochemistry and Applied Ethology

IRSEA never works to find coercive solutions, methods of eradication. But on the contrary, we have the search for coexistence and sharing of the world.

The development of semiochemical analogues opens the way to new ways of communicating with our pets as well as with farm animals or even with animals that are harmful to us (especially parasites).

This communication avoids the violence of commonly used methods to control these animals.


IRSEA has implemented eight major lines of research:



Chemical structure and relationship structure activity of semiochemicals:

It involves defining the chemical nature of the components of semiochemical secretions, studying the receptors and transport proteins with which they interact.

Détection des sémiochimiques et effets des sémiochimiques sur le système nerveux central:

By studying the systems of perception of these messages (vomero-nasal system, olfactory system) and their central connections and projections, the objective is to improve the understanding of the neurological, neuroendocrine and neuroimmune chains underlying the effects of semiochemicals.

Semiochemical emitting structures:

This axis focuses on both the description of the secretory glands and the study of the mechanisms of emission and secretion regulation.

Pathology of chemical communication:

This is a very innovative axis, born of the pioneering work of the IRSEA on diseases of the vomero-nasal organ. This axis focuses on the identification of lesion processes and malfunctions that may affect the detection and emission of semiochemicals, the study of their functional consequences, but also on diagnostic methods for their detection in clinical practice.

Role of semiochemicals in inter-individual relationships and sustainable interactions:

This axis aims to elucidate the role of semiochemicals in intra-specific relationships such as attachment, choice of sexual partner, social interactions, but also in mechanisms linking different species, such as predator-prey relationship, parasitism.

Parameters for evaluating emotional reactions:

The aim is to identify and validate, using clinical and zootechnical procedures, methods for objective evaluation of emotional reactions, through their physiological and behavioural consequences.

Use of semiochemicals in therapy:

This research area concerns the use of semiochemical analogues in behavioural, endocrine and neuroendocrine disorders, as well as in the treatment and prevention of parasitic diseases.

Use of semiochemicals in animal population management:

The aim here is to study the applications of semiochemicals in breeding domesticated species, but also in the management of competing species and troublesome behaviours of domesticated animals.
