The composition of honey samples of Plebeia wittmanni (n = 10) and Tetragonisca angustula fiebrigi (n = 12) was analysed. The colours of all collected honeys were amber to dark amber and the pH varied. Moisture was lower than reported for other stingless bee honeys. Conductivity and ash content of P. wittmanni honey were higher than for T. …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 ...Taxonomy information for Tetragonisca angustula. Find diseases associated with this biological target and compounds tested against it in bioassay experiments. Among stingless bees, Tetragonisca angustula is widely distributed in tropical habitats, and has been considered an important pollinator of different plant families. To support a rational economic use of this group, there is a need to characterize the plant species that represent important sources as part of their diet, as preferred, alternative or casual food …Application of neonicotinoid insecticides on crops can reduce the pollination services and population levels of the stingless bee Tetragonisca angustula (Latreille) (Hymenoptera: Apidae) in Neotropical agroecosystems. However, the impact of these insecticides on this bee has not been fully investiga …Jatai stingless bee or angelita bee Tetragonisca angustula at the wax entrance to their hive.

Parquet from solid Sucupira wood Bowdichia Nitida Benth or more commonly known as Brazilian Chestnut.Tetragonisca angustula (syn. Trigona angustula) 35 honey (Brazil) was provided as a gift. All stingless bee honey samples were stored in a refrigerator (4 °C) before analysis. Sugar standards. Authentic trehalulose (specified by supplier > 90% purity) was purchased from Biosynth Carbosynth (Staad, Switzerland). Maltose, sucrose, glucose and ...Native bees are important pollinators in neotropical forests. Tetragonisca angustula (Latreille) (Apidae: Meliponini) is a stingless bee widely distributed from the south of Mexico to Argentina.This research deals with the physicochemical characteristics of 20 samples of Tetragonisca angustula honey, from the municipality of Piracicaba, state of Sao Paulo, Brazil, contributing to the establishment of a quality standard for the honey produced by Brazilian stingless bees making possible the control of this product.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.Tetragonisca angustula. Polen de calabaza – Cucurbita ficifolia. Polen de flor de mayo – Palicourea sp. Polen de mestizo – Cupania americana. Polen de otra Asteraceae en miel de.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.The Meliponinae are important pollinators of plant species, and one of the most managed species is Tetragonisca angustula. 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.Fipronil was also highly toxic and presented a similar toxicity to both species, with 48-h LD50s of 0.5 ng/bee (A. mellifera) and 0.4 ng/bee (T. angustula). Imidacloprid had the lowest acute toxicity with a 48-h LD50 of 29 ng/bee for A. mellifera, whereas T. angustula tolerated exposure higher than 35 ng/bee. Apparent biomarker responses were ...Abstract. The plants providing nectar resources to Tetragonisca angustula were identified through melissopalynological analysis of 76 honey samples from eight states. A total of 306 pollen types ...Tetragonisca angustula is a stingless bee species widely distributed in Brazil. Past studies have shown a rich native flora supplying this meliponine with pollen and nectar. The aim of this study was to compare the food provisions of T. angustula in two areas in the Lower Amazon mesoregion in the state of Pará and two areas of caatinga ...Tetragonisca angustula fiebrigi / Plebeia wittmanni / Meliponini / composition / honey / antibacterial properties 1. INTRODUCTION More than 400-500 species of Neotropi-cal stingless bees occur in the tropical and subtropical regions of America (Wille, 1979; Roubik, 1995; Camargo and Pedro, 2007). Beekeeping with stingless bees, or meliponi-

Here we examined odor reception and gustatory responsiveness of the stingless bee Tetragonisca angustula focusing on workers, whose are involved in different tasks. Using the proboscis extension response, we studied sucrose response thresholds (SRTs) of foragers and guards. Peripheral responses to odors at the antennae were recorded by ...The results indicated that T. angustula has different levels of sensitivity to the four neonicotinoid insecticides, with no significant similarity among them, even for the insecticides in the same group (cyano or nitro radicals) (Table 1).Acetamiprid was the safest neonicotinoid for T. angustula, followed in descending order by thiacloprid, imidacloprid, …Tetragonisca angustula (Latreille), popularly known as "jataí", can signicantly contribute to strawberry yield (Malagodi-Braga and Kleinert 2004; Antunes et al. 2007), increasing income and ensuring quality to seed production of Salvia farinacea (Slaa et al. 2000). Moreover, has the potential to increase the produc-The species was previously described as Tetragonisca angustula fiebrigi subspecies along with T. a. angustula; however, molecular markers studies showed them to be distinct species [4, 5]. Among the species of stingless bees, T. fiebrigi is known as a good producer of honey and propolis, which are highly prized in folk medicine for their ...Melipona quadrifasciata and Tetragonisca angustula Hydroethanolic and aqueous extracts followed by hexane, dichloromethane, ethyl acetate, methanol, and methanol/acetic acid fractionation Rutin, quercetin, gallic acid, gallocatechin, epigallocatechin, p- OH-benzoic acid, epicatechin gallate, syringic acid, caffeic acid, epigallocatechin gallate ...
