Importancia de la genética de las abejas en meliponicultora 27Summary We displaced a small nest box containing stingless bees (Trigona (Tetragonisca)angustula) over distances of up to 1.6 meters in different directions and counted the numbers of returning ...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.

The antioxidant activity of Tetragonisca angustula honey (TAH) and its ethanolic extract (TAEE) were investigated. The total levels of phenolic (TPC) and flavonoids (TFC) were also evaluated. The results for TPC were 19.91 ± 0.38 and 29.37 ± 1.82 mg GAE g-1 and for TFC 0.20 ± 0.02 and 0.14 ± 0.01 mg …This study aimed to evaluate the quality of the honeys of Africanized bees (Apis mellifera) and Jataí (Tetragonisca angustula) and check for dirt and tampering, in addition to a brief comparison ...In this study, we investigated the chemical composition, and antioxidant and antibacterial properties of ethanolic extracts of propolis (EEP) from Melipona quadrifasciata quadrifasciata and Tetragonisca angustula. Chemical composition of EEP was determined by colorimetry and chromatographic (HPLC-DAD and UPLC-Q/TOF-MS/MS) analysis.

(Frieseomelitta) nigra, Scaptotrigona sp. and Nannotrigona sp. were studied through a year using Differential Scanning Calorimetry (DSC). Honey samples were collected every three months, during August 2014 to August 2015 and showed several thermal transitions (trs 1, trs 2, trs 3, trs 4a and ... bill self wins and Tetragonisca angustula. Simultaneously, we evaluate the local oristic components through seventeen rapid botanical surveys conducted at dierent distances from the nests. We discovered a broad set of explored oral sources, with 46.3 plant species per bee species in honey samples and 53.67 in pollen samples. kansas vs purduebrook barnettwhere are my teams recordings One study showed that the stingless bee Tetragonisca angustula is able to sense the modification of the magnetic field inclination. The aim of the present …High-temperature high-resolution gas chromatography (HT-HRGC) and HT-HRGC coupled to mass spectrometry (HT-HRGC-MS) were applied to the study of propolis collected by Apis mellifera and by Tetragonisca angustula, a stingless bee native to southeastern Brazil. With the exception of amino acids and erytrose/erythritol content, both propolis ...
