“…The room was open to the outside during experiments and thus maintained at ambient external air temperature and humidity (verified using a weather meter; Kestrel 4000, Boothwyn, PA, USA). Nest temperatures were generally 2-3°C cooler than external air temperatures in the food unloading area (away from the brood chamber) because of beebuilt insulation that prevented an immediate rise from the cooler evening temperatures (also observed in Tetragonisca angustula by Proni and Hebling, 1996). Colonies E and F (approximately 600 workers each) were kept inside their natural log nests and placed on the landing outside the lab (9°9.923ЈN, 79°50.193ЈW), where they had been for 3 years.…”

Corrigendum Nieh, J. C. and Sánchez, D. Effect of food quality, distance and height on thoracic temperature in the stingless bee Melipona panamica. J. Exp. Biol. 208,[3933][3934][3935][3936][3937][3938][3939][3940][3941][3942][3943] On the title page of this paper, Daniel Sanchez was incorrectly affiliated to Division of Biological Sciences, Section of Ecology, Behavior, and Evolution, University of California San Diego, MC#0116, 9500 Gilman Drive, La Jolla, CA 92093-0116, USAThe correct affiliation should have read:El Colegio de la Frontera Sur, Carretera Antiguo Aeropuerto km 2.5, 30700 Tapachula, Chiapas, Mexico.We apologise for any inconvenience caused by this error. 3933Thermoregulation is widespread among large-bodied insects (Heinrich, 1993), particularly the Hymenoptera (Himmer, 1932), wasps (Coelho and Ross, 1996;Stabentheiner et al., 2004), solitary bees (Baird, 1986;Chappell, 1982;May and Casey, 1983;Nicolson and Louw, 1982;Stone, 1993a) and social bees (Bujok et al., 2002;Kleinhenz et al., 2003;Seeley et al., 2003;Stabentheiner et al., 1990;Starks and Gilley, 1999). Thermoregulation has significant ecological consequences (Corbet et al., 1993) because internal heat generation enables solitary (Stone, 1994) and social bees (Heinrich, 1993) to forage and pollinate under colder ambient conditions compared to animals that cannot actively thermoregulate.Several studies have found evidence for thoracic temperature regulation during honeybee recruitment (Esch, 1960;Stabentheiner, 2001;Stabentheiner and Hagmüller, 1991;Waddington, 1990). Honeybees can regulate their body temperature according to food quality, exhibiting higher thoracic temperatures after feeding at richer food sources (Schmaranzer and Stabentheiner, 1988;Underwood, 1991). Thoracic temperature positively correlates with the quality of the food as perceived by sweetness (Stabentheiner and Hagmüller, 1991), proximity to the nest (Esch, 1960;Stabentheiner, 1996) and nectar flow rate (Farina and Wainselboim, 2001). Moreover, thoracic temperatures are affected by the status of the hive (amount of pollen and nectar stores) and are thus tuned to colony need (Schulz et al., 1998). Mechanistically, honeybee thoracic temperature is tied to metabolic expenditure, which increases with increasing sugar concentration and nectar flow rate (Moffatt and Nunez, 1997), and perhaps with forager motivational state (Balderrama et al., 1992). Honeybee thoracic temperature is tied to the thermal stability and the ability to generate high mechanical power output in flight (Dudley, 2000;Woods et al., 2005).To date, no studies have examined whether stingless bees have similar thermal abilities. We therefore hypothesized that food profitability to the colony would significantly affect the temperatures of recruiting meliponine foragers at the feeder and inside the nest.What little is known about meliponine thermoregulation largely concerns the regulation of nest temperatures, not individual thermoregulation (Kerr and Laidlaw, 1956;Kerr et al., 1967;Michener, 1974;Roubik...

“…Foraging meliponine thoracic temperature in the meliponines Scaptotrigona postica (Silva, 1981), T. a. fiebrigi and T. a. angustula (Proni and Hebling, 1996). Recently, Hrncir et al (2004) have shown that thoracic vibrations produced by recruiting M. seminigra foragers increase in duration with increasing food quality.…”

“…PRONI & HEBLING (1996) observaram um aumento nas taxas respiratórias juntamente com a elevação da temperatura em Tetragonisca angustula fiebrigi (Schwarz, 1938) e T. angustula angustula (Latreille, 1807). Além disso foi observado que, de modo geral, as taxas respiratórias foram mais elevadas no verão do que no inverno.…”

Os resultados obtidos sobre a influência da temperatura na taxa respiratória de forrageiras de T. spinipes (Fabricius, 1793) mostraram um aumento no consumo de oxigênio de acordo com o aumento das temperaturas. Também foi possível observar um metabolismo respiratório mais intenso no inverno do que no verão, principalmente nas temperaturas entre 30 e 35ºC. Os resultados da análise de variância fatorial, comparando-se verão e inverno mostraram diferenças significativas entre as temperaturas 15; 20 e 30ºC. Com relação às preferências térmicas observouse tanto no inverno como no verão um intervalo entre 20 e 30ºC, sendo que o consumo de oxigênio estabilizou mostrando uma possível faixa térmica ideal para essa espécie de abelha.

Foi determinado em operárias isoladas de Tetragonisca angustula fiebrigi (Schwarz, 1938), T. a. angustula (Latreille, 1807) e Trigona spinipes (Fabricius, 1793) o ritmo circadiano das taxas respiratórias médias (VO2) em condições de ciclo normal (dia/claro e noite/escuro), durante a primavera. O consumo de oxigênio foi determinado a 30ºC usando um respirômetro de Warburg. A análise estatística dos resultados revelou interações significativas entre intervalos de tempo e entre as espécies. Foram comparadas as taxas respiratórias usando o teste do Tukey. Um padrão definido de ritmo circadiano metabólico foi observado para ambas as espécies, apresentando um maior consumo de oxigênio durante o dia, com um pico entre 10:00 e 15:00. À noite o consumo diminuiu, alcançando os níveis mínimos entre 2:00 e 3:00. Tetragonisca angustula angustula e T. a. fiebrigi não apresentaram diferenças significativas entre si, mas diferiram de T. spinipes, que apresentou taxas respiratórias maiores.
