Worker Matricide in Social Bees and Wasps
Journal of Theoretical Biology, 1994Abstract In bumble bees (Bombus) and vespine wasps (Vespa, Vespula, Dolichovespula), workers have regularly been observed to kill their colony's single queen (worker matricide). Workers gain a fitness payoff in worker-produced males from matricide because it removes the queen's inhibition over their reproduction.

Honey bee workers as mobile insulating units
Insectes Sociaux, 2005Heat-shielding is a method used by honey bee workers to insulate temperature sensitive brood from localized heat stress during development. Due largely to data collection techniques, heat-shielding has been defined as stationary bees congregating with their ventral side facing the heat stress.

Work connotes activity, effecting or bringing something about. The worker does something physically and/or mentally, and whatever is “worked” has been acted upon. Work is a denial of passivity, and thus a manifestation of force or power. Indeed, the association of work with force sometimes invites a further conjunction between work and violence.

The metabolic fate of nectar nicotine in worker honey bees
Journal of Insect Physiology, 2017Honey bees (Apis mellifera) are generalist pollinators that forage for nectar and pollen of a very large variety of plant species, exposing them to a diverse range of secondary metabolites produced as chemical defences against herbivory. Honey bees can tolerate high levels of many of these toxic compounds, including the alkaloid nicotine, in their diet

When Workers Disunite: Intraspecific Parasitism by Eusocial Bees
Annual Review of Entomology, 2008One of the most obvious characteristics of an insect society is reproductive cooperation. Yet insect colonies are vulnerable to reproductive parasitism, both by workers from their own colony and by workers from others. Little is known about the mechanisms insect societies have evolved to protect themselves from being exploited from within and outside ...

Dancers, Workers and Bees in the Choreography of Doris Humphrey
Dance Research Journal, 1996Doris Humphrey's deep humanistic concerns, as stated in dances such as New Dance and Passacaglia, and her dedication to the group as the most essential element of choreography might have allied her with those enthusiastic and vociferous dancers in the 1930s who were dedicated to effecting social change through movement.

Laying Worker Honey Bee: Similarities to the Queen
Nature, 1965IT is known that in the honey bee community the queen has an influence on the behaviour and the physiology of worker bees1–3. It has been shown that the presence of a queen in a group of worker bees inhibits the development of the ovaries in the workers3. The workers, showing a special behaviour (retinue behaviour) towards their queen, recognize her by

The influence of a queen on the ovary development in worker bees
Experientia, 1956Unabhangig voneinander haben in den letzten Jahren einerseitsButler, andererseitsde Groot undVoogd gefunden, dass der Einfluss, den die Anwesenheit einer Konigin auf die Arbeiterinnen der Honigbiene ausubt, durch Aufnahme einer Substanz bedingt ist, die die Arbeiterinnen vom Korper der Konigin ablecken, und die vonButler als «queen substance ...

How worker bees perceive the presence of their queen
Zeitschrift f�r Vergleichende Physiologie, 19591. Die Anwesenheit der Bienenkonigin ubt bekanntlich einen hemmenden Einflus aus auf die Ovarienentwicklung bei den Arbeiterinnen. Es werden einige Tatsachen angefuhrt, die darauf hindeuten, das der Entwicklungszustand der Ovarien bei Arbeiterinnen in normalen Bienenvolkern auserdem stark von den Wetter- und Trachtverhaltnissen abhangig ist.
