Análise térmico de mel de Trigona (Tetragonisca) angustula de Norte de Santander, Colômbia Yaneth Cardona-Rodríguez 1 , Diana Alexandra Torres-Sánchez 2 , Wolfgang Hoffmann 31. In the stingless bee, Trigona (Tetragonisca) angustula, hovering guard bees keep their position relative to a moving stripe pattern mounted on the front face of the nest box constant by flying forwards and backwards parallel to the pattern movement (Fig. 2). 2. The response is guided by two cues: (1) image position and motion of the pattern and (2) the retinal position of the nest entrance ...Sugar alcohols had also been documented in Brazilian Melipona sp. and Tetragonisca angustula propolis extracts . However, hydrocarbons such as silane and butane were only identified in T. binghami extracts. Silane in propolis extracts can be used for wood protection effectively as biofriendly hydrophobic agents.

Initially, two subspecies were identified in T. angustula: T. angustula angustula and T. angustula fiebrigi. Subsequently, T. a. fiebrigi was considered a species, based on the coloration of its mesepisternum.

Tetragonisca angustula is an eusocial stingless bee that presents a sophisticated system of defense involving two complementary groups of guards: hovering and standing guards. We identified, quantified, and compared the cuticular compounds of worker bees captured within the nest, and bees performing tasks outside: foragers and guards. ...The relative cultural importance index recorded 30 specific uses for bee products grouped in four categories, from which 29 were attributed (but not exclusively) to Tetragonisca angustula, making it the most versatile species.

Even within a single colony, nest closure behavior can vary day to day. However, little is known about what cues mediate nest closure, or which individuals in the colony are performing this behavior.We characterized Tetragonisca angustula and Melipona beecheii honeys produced in Costa Rica according to their physical and chemical properties. Moreover, we found critical parameters that distinguish the honeys from each other. Forty-eight samples of honey of both stingless bee species were analyzed (T. angustula, n = 32; M. beecheii, n = 16).Aims: The antibacterial activity against Staphylococcus aureus of honey and propolis produced by Apis mellifera and Tetragonisca angustula was evaluated. Secondary aims included the study of the chemical composition of propolis and honey samples and its relationship with antibacterial activity against S. aureus.
