In this paper we show the results of investigating the presence of organochlorine pesticides in honey and pollen samples from managed colonies of the honey bee, Apis mellifera L. and of the stingless bee Scaptotrigona Mexicana Guérin. We found that 88.44% and 93.33% of honey samples, and 22.22% and 100% of pollen samples of S. mexicana and A. mellifera, respectively, resulted positive to at least one organochlorine. The most abundant pesticides were DDE, DDT, Endrin and heptaclor. Despite the low foraging range of S. mexicana the number of pesticides detected in the honey samples was similar to that of A. mellifera. Paradoxically we a found a small number of organochlorines in pollen samples of S. mexicana, perhaps indicating a rapid turnover of this material as compared to A. mellifera.

<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>

Scientific studies about the antibacterial effects of honeydew honey produced by the stingless bee are very limited. In this study, the antibacterial activities of 46 blossom and honeydew honeys produced by both honey bees and stingless bees were evaluated and compared. All bacterial isolates showed varying degrees of susceptibility to blossom and honeydew honeys produced by the honey bee (Apis cerana) and stingless bee (Heterotrigona itama and Geniotrigona thoracica) in agar-well diffusion. All stingless bee honeys managed to inhibit all the isolates but only four out of 23 honey bee honeys achieved that. In comparison with Staphylococcus aureus, Escherichia coli was found to be more susceptible to the antibacterial effects of honey. Bactericidal effects of stingless bee honeys on E. coli were determined with the measurement of endotoxins released due to cell lysis. Based on the outcomes, the greatest antibacterial effects were observed in honeydew honey produced by H. itama. Scanning electron microscopic images revealed the morphological alteration and destruction of E. coli due to the action of this honey. The combination of this honey with antibiotics showed synergistic inhibitory effects on E. coli clinical isolates. This study revealed that honeydew honey produced by H. itama stingless bee has promising antibacterial activity against pathogenic bacteria, including antibiotic resistant strains.

Honey bees play a vital role in providing pollination services for agricultural crops and wild flowering plants. However, the spillover risk of their pathogens to other pollinators or wild insects is becoming a cause for concern. There is some evidence that stingless bees can carry honey bee viruses, but little is known about the presence of honey bee viruses in stingless bees in China. Here, we investigate the occurrence of major honey bee pathogens including bacteria, fungi, and viruses in stingless bees (Apidae: sp.). Our results show that the stingless bees (Apidae: sp.) were mainly infected with DWV-A, but no DWV-B and DWV-C. Phylogenetic analysis on fragments of lp, RdRp, and VP3 of DWV-A indicated that genetic variation in VP3 might an important indicator for host-specific viruses, but it requires further study. Our results indicated that DWV-A is not only the major strain of virus currently circulating in managed bee colonies in China and globally, but in stingless bee species as a whole.
