Short Period

The demand for stingless bee colonies in Malaysia has considerably increased due to the rapid advance of meliponiculture in using the stingless bees as agricultural pollinators, as well as the commercialization of stingless bee products (i.e. honey, bee bread and propolis). Thus, in vitro queen rearing for a large scale and rapid colony multiplication must be developed in order to fulfil the public requirements in a short period. Little is known about the in vitro rearing of native stingless bee queen, Heterotrigona itama. Therefore, in this study, we investigated the amount of larval food required by H. itama queen by comparing three different amounts of larval food, viz., 100 µL, 120 µL and 150 µL. All treatments were controlled under 100% relative humidity for the first 6 days, and 75% relative humidity for the rest of larval development until queen adult emergence, under 30 °C incubator temperature. The results showed that larvae of H. itama treated with the highest amount of larval food (150 µL) led to 78% of the queen’s emergence, whereas larvae treated with 120 µL and 100 µL of larval food resulted in 40% and 0% of queen emergence. The dynamic survival curve showed that most of the larvae died before the pupation phase and reached constant stability afterward. The queen’s body and abdominal length were significantly greater than wild workers. Microscopy analysis showed that in vitro queen had well-developed reproductive system with a huge ovary and spermatheca, whereas wild worker had much smaller ovary without spermatheca. Outcomes from this study could help increase the number of colonies on a large scale, allowing for their use both ecologically and economically, and contribute to conservation efforts in native species of stingless bees.

<p>La interacción planta-abeja puede generar productos de la colmena con diferentes características fisicoquímicas, bioactivos y actividad antimicrobiana. Por lo cual, en este trabajo se determinó la composición química de conglomerados o agregados de polen colectados de 12 colmenas establecidas en Chiapas, México, en los municipios Tapachula, Mazatán y Cacahoatán, dentro de tres meliponarios comerciales asociados a las especies: <em>Melipona beecheii</em>, <em>Scaptotrigona mexicana</em> y <em>Tetragonisca angustula</em>. Asimismo, se evaluó el efecto de los agregados de polen en <em>Colletotrichum gloeosporioides</em>. Se encontró una composición química muy diversa independientemente de la especie de abeja. El polen obtenido de colmenas con <em>M. beecheii</em> tuvieron la mayor cantidad de fenoles, flavonoides y acidez libre. Estas propiedades, en adición de la capacidad antioxidante (trolox), glucosa y pH, estuvieron asociados a la inhibición del crecimiento <em>in vitro</em> de<em> C. gloeosporioides</em>. La velocidad de crecimiento radial del hongo durante nueve días fue de 0.013 a 0.009 mm h-1 con extractos de polen, 44 % menor que el efecto del clorotalonil. La actividad antifúngica de los extractos de polen fue de 65 y 37 % para <em>M. beecheii</em>, 57 y 16 % para <em>T. angustula</em> y 60 y 30 % para S. mexicana, respecto al tratamiento testigo y a la dosis más alta de clorotalonil, respectivamente.</p>

The stingless bee, Melipona fasciculata Smith (Apidae, Meliponini), is a native species from Brazil. Their products have high biotechnological potential, however there are no studies about the biological activities of pollen collected by M. fasciculata. In this context, the present study investigated the chemical composition, anti-oxidant, anti-inflammatory, and analgesic activities of hydroethanolic pollen extracts collected by M. fasciculata in three cities in Maranhão State, Brazil. We verified the antioxidant activity of the extracts and inhibitory activity against the cyclooxygenase enzyme using in vitro assays and in allowed to select the extract with higher efficiency to be used on in vivo assays. In these trials, the selected extract showed high anti-inflammatory activity as well as nociceptive effects at central and peripheral level, suggesting that this extract acts on inhibition of histamine release and decreased synthesis of prostaglandins and the in-silico study suggested that polyphenols and acids fatty acids in the extract may be associated with these activities. The results of the present study report the high biological potential of pollen extract and we conclude that the pollen collected by M. fasciculata can be considered as the object of research for new pharmacological alternatives.
