Brood parasitism reduces but does not prevent Bombus terrestris reproductive success

open access: yesInsect Science, EarlyView.
Graphical depiction of the colony splitting process. Throughout figures in this paper, results pertaining to host success are represented in blue, and cuckoo success is represented in red. Abstract Cuckoo bumblebees are obligate brood parasites that must invade a colony of their host bumblebee species in order to reproduce.

The choice of drinking water by the honeybee

open access: yes, 1940
A brief review of the literature on this subject is given. By means of "training table" experiments in which use was made of the Latin square system in order to allow of rapid statistical analysis of the results obtained, it was shown that: (1) The ...

Number of honeybee colonies in areas with high and low beekeeping activity in Southern Mexico [PDF]

open access: yes, 2013
The number of colonies in feral and managed honeybee populations (Apis mellifera) was determined for various sampling locations in Chiapas and Yucatan (Mexico) to assess the impact of apiculture on feral honeybee populations.

Division of labour in the honeybee community

open access: yes, 1952
Newly emerged bees in a colony were individually marked, and their foraging activities were studied by subsequent observations at the hive entrance. A few individuals gathered pollen throughout their foraging lives; a considerable number gathered none at

The defence of the honeybee community [PDF]

open access: yesProceedings of the Royal Society of London. Series B - Biological Sciences, 1954
Abstract Pairs of colonies of differently coloured bees were placed with their entrances only 2 in. apart, and m any bees tried to enter the wrong colony, as if it were their own. Strangers were recognized by their different scent, and their reception depended upon foraging conditions.

Spatial and seasonal patterns of potential orchard pollinators across a Lake Ontario gradient

open access: yesAgricultural and Forest Entomology, EarlyView.
Potential pollinator captures varied by season, trap height and distance from Lake Ontario, indicating that flower visitors were not evenly distributed during apple bloom. Several common bee genera, including Lasioglossum, Agapostemon, Andrena and Apis, overlapped more closely with apple bloom than the dominant retained fly genus, Toxomerus.

Postmortem morphology of honeybee stings induced fatal anaphylaxis

open access: yes
Despite numerous case reports in the literature, high-quality postmortem images of honeybee sting are scant in postmortem literature. We report a case of a fatal anaphylactic death from honeybee stings with detailed high-quality annotated macroscopic and

An investigation of the long-term effects of early developmental stress exposure in the Honeybee (Apis mellifera) [PDF]

open access: yes, 2019
Honeybees (Apis mellifera) are organisms of an utmost importance to scientific advancement, food security and agricultural systems. Unfortunately, managed honeybee colonies are dying at alarming rates in much of the Northern Hemisphere, particularly in ...

Addition and subtraction by honeybees [PDF]

open access: yesLearning & Behavior, 2019
Howard, Avargues-Weber, Garcia, Greentree, and Dyer (Science Advances, 5,1-6, 2019) report experiments in which honeybees initially shown a number of shapes could subsequently choose a pattern that added or subtracted one from that number. Further, the operations of addition and subtraction were cued by the colors of the shapes.

Safety of Venom Immunotherapy in Pregnancy: A Multicentre Study

open access: yesAllergy, EarlyView.
Venom immunotherapy (VIT) during pregnancy, when maintenance dose is well tolerated, can be continued. No increased risk of adverse effects to VIT or safety concerns for the pregnancy or the newborns were observed. No decreased efficacy of VIT, in case of re‐stings, was reported.
