Killing and replacing queen-laid eggs: low cost of worker policing in the honey bee [PDF]

open access: yes, 2014
Worker honeybees, Apis mellifera, police each other’s reproduction by killing worker-laid eggs. Previous experiments demonstrated that worker policing is effective, killing most (∼98%) worker-laid eggs. However, many queen-laid eggs were also killed (∼50%

Protocol for the in vitro rearing of honey bee (Apis mellifera L.) workers

open access: yes, 2016
The in vitro rearing of worker honey bees (Apis mellifera L.) has become an increasingly important method in honey bee research in general, and in pesticide risk assessment specifically.

Heterospecific Hymenoptera found inside the nests of Bombus impatiens (Hymenoptera: Apidae). [PDF]

open access: yes, 2018
The nests of social Hymenoptera are particularly attractive to species engaging in resource robbing due to their concentration of resources. Here, the identity of heterospecific intruders in Bombus impatiens nests are described, with a particular focus ...

Hoarding by honeybees (Apis mellifera L.)

open access: yesAnimal Behaviour, 1972
Abstract The food hoarding by groups of fifty bees kept in small cages and provided with sugar syrup was studied. Less food was stored in a new comb than in an old one, whether the old comb had been used for storing food or rearing brood, and there was less in drone than in worker combs.

Deformed Wing Virus Infection in Honey Bees (Apis mellifera L.)

open access: yesVeterinary Pathology-Supplement, 2019
Deformed wing virus (DWV) is a single-stranded RNA virus of honey bees (Apis mellifera L.) transmitted by the parasitic mite Varroa destructor. Although DWV represents a major threat to honey bee health worldwide, the pathological basis of DWV infection ...
