Chemical communication in the honeybee (Apis mellifera L.): a review

open access: yesVeterinární Medicína, 2011
An important area of physiology of the honeybee (Apis mellifera) is chemical communication between individuals and castes in the swarm, which maintains its integrity and function.

Specific Cues Associated With Honey Bee Social Defence against Varroa destructor Infested Brood

open access: yesScientific Reports, 2016
Social immunity forms an essential part of the defence repertoire of social insects. In response to infestation by the parasitic mite Varroa destructor and its associated viruses, honey bees (Apis mellifera L.) have developed a specific behaviour (varroa-

Improved Pollination Efficiency and Reduced Honey Bee Colony Decline in Greenhouses by Allowing Access to the Outside During Part of the Day

open access: yesSociobiology, 2018
Although honey bees are efficient pollinators of many crops cultivated in greenhouses, it is difficult to maintain colony strength and consequently pollination efficiency. Many bees die under greenhouse conditions and the colonies rapidly weaken.

Brood reduction caused by sibling cannibalism in Isodontia harmandi (Hymenoptera: Sphecidae), a solitary wasp species building communal brood cells.

open access: yesPLoS ONE, 2022
Sibling rivalry or brood reduction prevailing within bird nests is effectively avoided in solitary aculeate nests because the larvae of wasps and bees usually develop in each brood cell.

The sight of an adult brood parasite near the nest is an insufficient cue for a honeyguide host to reject foreign eggs. [PDF]

open access: yes, 2015
Hosts of brood-parasitic birds typically evolve anti-parasitism defences, including mobbing of parasitic intruders at the nest and the ability to recognize and reject foreign eggs from their clutches.

Male survivorship and the evolution of eusociality in partially bivoltine sweat bees

open access: yesPLoS ONE, 2022
Eusociality, where workers typically forfeit their own reproduction to assist their mothers in raising siblings, is a fundamental paradox in evolutionary biology.

Assessing the Consequences of Brood Parasitism and Nest Predation On Seasonal Fecundity in Passerine Birds [PDF]

open access: yes, 1995
Brood parasites and nest predators reduce the seasonal fecundity and, hence, the population growth rates of their victims. However, most field studies do not measure directly how parasites and predators decrease seasonal fecundity, but instead measure ...

Brood overlap and male ornamentation in the double-brooded barn swallow [PDF]

open access: yesBehavioral Ecology, 2010
Brood overlap can be an optimal solution to the intraseasonal trade-off in the allocation of time between successive broods. In line with life-history theory, the extent of brood overlap should be adjusted according to the individual costs and benefits of the simultaneous investment into 2 broods. Phenotypic quality can affect these costs and benefits.
