Africanized honey bees are efficient at detecting, uncapping and removing dead brood

Genetics and Molecular Research, 2009
The hygienic behavior of honey bees is based on a two-step process, including uncapping and removing diseased, dead, damaged, or parasitized brood inside the cell. We evaluated during periods of 1 h the time that hygienic and non-hygienic colonies of Africanized honey bees spend to detect, uncap and remove pin-killed brood using comb inserts with ...

Getting more than a fair share: nutrition of worker larvae related to social parasitism in the Cape honey bee Apis mellifera capensis

, 2002
Besides activation of ovaries and thelytokous reproduction of Cape workers, larval nutrition is an important aspect in parasitism of the African honey bee.

Hygienic behaviour in Brazilian stingless bees

Biology Open, 2016
Social insects have many defence mechanisms against pests and pathogens. One of these is hygienic behaviour, which has been studied in detail in the honey bee, Apis mellifera.

Neodymium‐Doped Nanocrystals for Sensing Cellular Temperature at the Nanoscale

Advanced Optical Materials, EarlyView.
Neodymium‐doped NaYF4 nanocrystals are engineered as bright, biocompatible nanothermometers for intracellular temperature mapping. Their ratiometric near‐infrared emission enables highly sensitive, nanoscale thermal readouts in living cells. Combined with gold nanostars for photothermal therapy, they reveal pronounced subcellular heating heterogeneity ...

Removal new alternative to chemical and mechanical removal for the study of pollen carried on the wild bee scopae

Revista del Museo Argentino de Ciencias Naturales, 2010
Eliminación de una nueva alternativa a la eliminación química y mecánica para el estudio del polen transportado en las abejas silvestres. El reconocimiento taxonómico y la cuantificación de los diferentes tipos de polen recogidos por las abejas ofrecen el método más directo para estudiar la dieta.

Honey bee hygienic behaviour does not incur a cost via removal of healthy brood [PDF]

Journal of Evolutionary Biology, 2013
AbstractIn the honey bee, hygienic behaviour, the removal of dead or diseased brood from capped cells by workers, is a heritable trait that confers colony‐level resistance against brood diseases. This behaviour is quite rare. Only c. 10% of unselected colonies show high levels of hygiene. Previous studies suggested that hygiene might be rare because it

Cross‐Scale Hierarchical Targeted Delivery System Based on Small‐Scale Magnetic Robots

Advanced Robotics Research, EarlyView.
This article reviews a cross‐scale hierarchical targeted delivery system that integrates magnetic continuum robots and magnetic microrobots. By combining rapid long‐range navigation with precise microscale targeting, the system overcomes key limitations of single‐scale approaches.
