El interés se suscita a partir de que es una de las más asediadas por las personas para obtener su miel, provocando eliminación total de lasNative from tropical and subtropical regions, M. quadrifasciata quadrifasciata and Tetragonisca angustula are locally known as Mandaçaia and Jataí, respectively. Interestingly, the propolis from M. quadrifasciata quadrifasciata is known as geopropolis because it presents soil traces in its composition . Due to the unique behavioral and ...Jul 31, 2021 · Tetragonisca angustula colonies either close, partially close, or leave open the nest entrance tube (Roubik 1992; Grüter et al. 2011). 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. Torres A, Garedew A, Schmolz E, Lamprecht I. Calorimetric investigation of the antimicrobial action and insight into the chemical properties of ‘angelita’ honey – A product of the stingless bee Tetragonisca angustula from Colombia. …Since chemical or pharmacological studies on the propolis of Brazilian native bees are scarce, the aim of this study was to evaluate the chemical profile, the antioxidant, cytotoxic and antibacterial activity of aqueous and hydro-alcoholic extracts and isolated compounds of propolis of the native bees, Melipona quadrifasciata and Tetragonisca angustula, …Tetragonisca angustula and T. fiebrigi esterases were biochemically characterized by their inhibition pattern and thermostability. Workers of both species were collected from nests at the State University of Maringa. In T. fiebrigi three esterases were observed: EST-1 (β-esterase, cholinesterase I), EST-2 (α-esterase, cholinesterase II) and ...Jan 15, 2021 · Tetragonisca angustula.

When exposed to half the commercial concentration of GLY, adults of A. mellifera and the stingless bee Tetragonisca angustula Latreille, 1811 (Hymetoptera: Apidae) started to present mortality within 44 min, and after 12 h, there was 100% mortality (Ruiz-Toledo and Sánchez-Guillén, 2014).Tenemos le gusto de presentar algunos usos que tradicionalmente se le han dado a la miel de abejas Angelitas(Tetragonisca angustula) por parte de las comunid...Stingless bees (Meliponini) are highly social bees that are native to tropical and sub-tropical ecosystems. Resin use is vital to many aspects of stingless bee colony function. Stingless bees use resin to build essential nest structures, repel predators, and kill would-be invaders. Furthermore, resin-derived compounds have been found to enrich …Apr 24, 2019 · Tetragonisca angustula colonies thus employed a coordinated set of specialization strategies in nest defense: morphologically specialized soldiers, age polyethism among soldiers within specific guarding tasks, and rapid flexible reallocation of nonspecialists to guarding during soldier loss. This mixed strategy achieves the benefits of a highly ... This research was carried out to evaluate the population genetics of Tetragonisca angustula by isoenzymatic polymorphism. Five adult worker bees collected from 16 colonies maintained at the municipalities of Ivatuba-PR and five colonies from Dracena-SP were individually homogenized, and then submitted to electrophoresis.Aug 28, 2017 · 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. Recent research has shown that entrance guards of the stingless bee Tetragonisca angustula make less errors in distinguishing nestmates from non-nestmates than all other bee species studied to ...Differential expression analyses in Tetragonisca angustula In T. angustula , a total of 241 superTranscripts were differentially expressed between nurses and foragers (Supplementary Figure S2 ).Tetragonisca angustula.
