Chemical residues in beebread, honey, pollen and wax samples collected from bee hives placed on canola crops in Western Australia

Samples were collected from bee hives where bees had foraged on genetically modified, seed-treated and non-seed treated canola crops from July to September 2014. Chemical analysis of 240 beebread, honey, pollen and wax samples detected 14 chemical residues with overall detections averaging 1.22 chemicals per sample. Contamination was highest in pollen (2.31) followed by beebread (1.69), wax (1.43) and honey (0.32). The dominant chemicals were the herbicides atrazine and trifluralin, followed by the insecticide chlorpyrifos. Of the seed treatment neonicotinoids, imidacloprid was detected in ten beebread, pollen and honey samples and thiamethoxam was only found in one honey sample. None of the pesticide residues reported from bee hives were likely to pose a risk to honey bees as indicated by a comparison to the LD50 data. From September to December, bee hives produced honey with mean weights ranging from 18.6 to 35 kg/hives. Residuos químicos en muestras de pan de abejas, miel, polen y cera recolectados de colmenas colocadas en cultivos de canola en Australia Occidental Se recogieron muestras de colmenas en las que las abejas se habían alimentado de cultivos de canola modificada genéticamente con semillas tratadas o no tratados entre julio y septiembre de 2014. El análisis químico de 240 muestras de pan de abejas, miel, polen y cera detectó 14 residuos químicos con un promedio de 1.22 productos químicos por muestra. La mayor contaminación se produjo en el polen (2.31), seguido del pan de abejas (1.69), la cera (1.43) y la miel (0.32). Los productos químicos dominantes fueron los herbicidas atrazina y trifluralina, seguidos del insecticida clorpirifós. De las semillas tratadas con neonicotinoides, el imidacloprid se detectó en diez muestras de pan de abejas, polen y miel y el tiametoxam sólo se encontró en una muestra de miel. Ninguno de los residuos de plaguicidas notificados en las colmenas podía representar un riesgo para las abejas melíferas, como lo indica una comparación con los datos de LD50. De septiembre a diciembre, las colmenas produjeron miel con pesos medios que oscilaron entre 18.6 y 35 kg/colmena.
