The hydrodistillated essential oils from leaves and fruits of Ecballium elaterium were analysed by GC-MS. Octyl octanoate (30.0%), 3-(6,6- dimethyl-5-oxohept-2-enyl)-cyclohexanone (20.4%) and hexahydro farnesyl acetone (19.1%) were the main components among 21 constituents characterised in the leaf oil. Twenty-one compounds
Stingless bees of the species Trigona spinipes (Fabricius 1793) use their saliva to lay scent trails communicating the location of profitable food sources. Extracts of the cephalic labial glands of the salivary system (not the mandibular glands, however) contain a
The distribution of water and the formation of microphases during the synthesis of octyl octanoate and the hydrolysis of triolein catalyzed by immobilized lipase have been directly monitored in real time using confocal laser microscopy.

Foragers can improve search efficiency, and ultimately fitness, by using social information: cues and signals produced by other animals that indicate food location or quality. Social information use has been well studied in predator-prey systems, but its functioning within a
The chemical composition of essential oil obtained by hydrodistillation from the dried fruits of Zosima absinthifolia was analysed by GC-MS. Twenty-four compounds were characterised in the oil. The major components of the oil were octyl acetate (87.48%), octyl octanoate (5.03%)
