Résumé : ABSTRACT The poison gland of minor workers of P.pallidula.Nyl. contains 3‐ethyl‐2,5‐dimethylpyrazine which induces trail‐following in other workers, but does not account for the full trail‐following effect of one worker's poison gland. No pyrazines were detected in major workers and their glands do not contain the pheromone. Copyright © 1988, Wiley Blackwell. All rights reserved
