Middle-Aged Worker Bees Express Higher Innate Immunity than Young Worker Bees in the Abdomen without the Digestive Tract of Worker Bees Reared in an Incubator

open access: yesInsects, 2022
Honey bees (Apis mellifera) can be reared in an incubator to study the mechanisms of aging and longevity; however, whether breeding in an incubator and using the abdomen without the digestive tract influences the expression of immune genes is unclear.

Drone and Worker Brood Microclimates Are Regulated Differentially in Honey Bees, Apis mellifera. [PDF]

open access: yesPLoS ONE, 2016
BACKGROUND:Honey bee (Apis mellifera) drones and workers show differences in morphology, physiology, and behavior. Because the functions of drones are more related to colony reproduction, and those of workers relate to both survival and reproduction, we ...

Chronic High Glyphosate Exposure Delays Individual Worker Bee (Apis mellifera L.) Development under Field Conditions

open access: yesbioRxiv, 2020
The ongoing debate about glyphosate-based herbicides (GBH) and their implications for beneficial arthropods give rise to controversy. This research was carried out to cover possible sublethal GBH effects on brood and colony development, adult survival ...

Changes in the Gene Expression Profiles of the Hypopharyngeal Gland of Worker Honeybees in Association with Worker Behavior and Hormonal Factors. [PDF]

open access: yesPLoS ONE, 2015
The hypopharyngeal glands (HPGs) of worker honeybees undergo physiological changes along with the age-dependent role change from nursing to foraging: nurse bee HPGs secrete mainly major royal jelly proteins, whereas forager HPGs secrete mainly α ...

The Pathogen Profile of a Honey Bee Queen Does Not Reflect That of Her Workers

open access: yesInsects, 2020
Throughout a honey bee queen’s lifetime, she is tended to by her worker daughters, who feed and groom her. Such interactions provide possible horizontal transmission routes for pathogens from the workers to the queen, and as such a queen’s pathogen ...

Mathematical Model and Dynamics Analysis of the Stingless Bee (Trigona sp.) in A Colony

open access: yesCommunication in Biomathematical Sciences, 2023
Trigona sp. is a stingless bee species that is widely distributed in tropical countries. It has castes in the colony, i.e. queen, worker, and male bee. Despite its size, Trigona sp.

Indirect exposure to insect growth disruptors affects honey bee (Apis mellifera) reproductive behaviors and ovarian protein expression.

open access: yesPLoS ONE, 2023
Pesticide exposure and queen loss are considered to be major causes of honey bee colony mortality, yet little is known regarding the effects of regularly encountered agrochemicals on honey bee reproduction.

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

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

Egg viability and worker policing in honey bees [PDF]

open access: yesProceedings of the National Academy of Sciences, 2004
In many species of social Hymenoptera, unmated workers can lay eggs that will produce males by parthenogenesis. Nevertheless, in queenright honey bee colonies ( Apis mellifera ), worker reproduction is low. One possible mechanism for this difference is worker policing, the removal of worker-laid eggs by other ...

Working-class royalty: bees beat the caste system [PDF]

open access: yes, 2005
The struggle among social classes or castes is well known in humans. Here, we show that caste inequality similarly affects societies of ants, bees and wasps, where castes are morphologically distinct and workers have greatly reduced reproductive ...
