Isobutyric acid from the Brindley's glands of Triatoma lecticularia.

The contents of the Brindley's gland of Triatoma lecticularia (Stål) (Heteroptera: Reduviidae: Triatominae) have been identified by gas chromatography-mass spectrometry as isobutyric acid. This compound is found in similar secretions from certain other members of the Triatominae, and is suggested to play a role as a defensive pheromone and for intraspecies communication.
