Chemical signals serve as the primary mode of communication among animals, particularly arthropods. These signals play integral roles in numerous behavioural aspects like sexual attraction, aggregation, trail following, recruitment, defence, host location, and various other behavioural functions.
The discovery of the sex pheromone in the silkworm, Bombyx mori, in 1959 marked a significant turning point. Since then, an extensive body of literature has emerged, detailing the identification of chemical signals that regulate a broad spectrum of animal behaviours and their interactions within their environment.
This wealth of knowledge reflects the intricate network of chemical communication governing diverse animal behaviours, highlighting the pivotal role of chemical cues in shaping their interactions and behaviours.

The main goal of The Pherobase is to convert scientific data and knowledge from the literature and published peer-reviewed information about behavioural modifying chemicals into electronically searchable database entries. The Pherobase is extensively linked, user-friendly, easy to understand and to follow. Currently, there are over 30,000 entries, 22,000 semiochemicals, around 185,000 organic compounds, and over 500,000 static php pages that make it the world’s largest database of behavior-modifying chemicals. In addition, mass spectral data, NMR, and synthesis data for more than 55,000 organic compounds are included.

Our commitment to The Pherobase involves rigorous efforts to ensure its comprehensiveness, reliability, and thoroughness. The Pherobase is intended for both scientific and non-scientific communities. For scientists, we aim to facilitate and expedite the process of identifying semiochemicals while offering insights into the shared chemical signals among various animal groups. Non-scientists can explore this platform as an engaging resource showcasing diverse animal behaviour.
The Pherobase stands as a valuable resource for educators and students delving into the realm of natural sciences. We sincerely hope that your visit to The Pherobase is enriching and fulfilling. We deeply value contributions from scientists and acknowledge them with gratitude.
