Guard bees are more likely to act as undertakers: variation in corpse removal in the bumble bee Bombus impatiens

Insectes Sociaux, 2019
Task specialization is one of the distinguishing features of social insect colony organization. Here we study the task of corpse removal (‘undertaking’) from the nest in three Bombus impatiens colonies. We determine (1) which task these bees perform when corpses are absent from the nest; (2) the degree to which worker body size relates to undertaking ...

Can Honey Bees Learn the Removal of a Stimulus as a Conditioning Cue?

Ethology, 2010
AbstractExperiments investigated a Pavlovian conditioning situation where the presence and absence of the stimulus are reversed temporally with respect to the presentation of a reward. Instead of a conditioned stimulus (e.g. odor) signaling the presence of a reward, the stimulus (e.g.

Grooming behavior by worker bees of various subspecies of honey bees to removeVarroa destructormites

Journal of Apicultural Research, 2015
Grooming behavior by honey bees is regarded as an important trait that contributes to the defense against the parasitic mite Varroa destructor. We carried out an assay to investigate how effective autogrooming by honey bees is in removing V. destructor mites.

The Effect of Leg Removal on Bees Held in Packages

Journal of Apicultural Research, 1969
SummaryThe extent to which bees kept in wire-screen packages lost their legs under various conditions of light and temperature, and the effect of such loss on foraging and hive duties, were studied. Few basitarsi were lost when packages were kept in the dark at 13°C, whereas large numbers were lost at 21° when alternate light and dark periods were used.

Smell of death leads bees to remove corpses

New Scientist, 2018
Honeybees pick up dead or diseased nestmates and drag them out of the hive. Removing corpses protects against infection, which can spread like wildfire in densely packed hives. In a 2017 study, they discovered two pheromones, called oleic acid and beta-ocimene, which are only released by dead bee larvae.

Learning and Task Interference by Corpse‐removal Specialists in Honey Bee Colonies

Ethology, 1997
AbstractUndertakers are considered to be among the most specialized of pre‐foraging honey bee (Apis mellifera L.) workers. In this study we examined a possible benefit and a cost of the corpse‐rem oval specialty, the improvement in performance with experience, and interference by individuals attempting to perform the same task in the same location ...

Pollen Deposition and Removal by Bees Visiting Two Tree Species in Panama

Biotropica, 1987
In lowland forests of Panama, Cochlospermum vitifolium and Cassia reticulata are nectarless, buzz-pollinated trees that require insect visitation to set seed; Cassia is self-compatible. Large anthophorid bees (Centris and Xylocopo spp.) were the primary pollinators of both species.

Pollen Removal by Bumble Bees and Its Implications for Pollen Dispersal

Ecology, 1990
Realized paternity should decelerate with increased allocation of resources to male function for hermaphroditic plants. If these diminishing returns result from the pollination process, total pollen dispersal would be maximized by restricting removal by individual pollinators and using the services of all available pollinators.

An effective approach for removing heavy salt-peppers noise based on bee colony optimisation

International Journal of Computational Science and Engineering, 2011
Image denoising is an important task in image analysis. To improve the performance of high-density salt and pepper noise denoising, a novel approach is proposed in this paper. This approach includes two steps. In the first step, the noise pixels are distinguished from the image pixels and set initial values for noise pixels; the second step denoising ...
