Nucleotide diversity based on csd gene of the black giant honey bee, Apis laboriosa (Hymenoptera: Apidae)

open access: yesEuropean Journal of Entomology, 2013
The mechanism of sex determination is common for all honeybee species (Apis spp.) by the complementary sex determi-nation (csd) gene. The csd gene has been studied in the Western honey bee (Apis mellifera L.), the Eastern honey bee (Apis cerana F.) and ...

Tracking large bees in open landscapes with active radio tags—Advantages and challenges using stationary receivers

open access: yesJournal of Animal Ecology, EarlyView.
Studying the spatial ecology of ecologically relevant species supports the development of effective conservation strategies. Recent technological advancements in remote tracking methods now enable researchers to study large flower‐visiting insects and important pollinators, such as carpenter bees.

Anarchy in the UK: Detailed genetic analysis of worker reproduction in a naturally occurring British anarchistic honeybee, Apis mellifera, colony using DNA microsatellites [PDF]

open access: yes, 2002
Anarchistic behaviour is a very rare phenotype of honeybee colonies. In an anarchistic colony, many workers’ sons are reared in the presence of the queen. Anarchy has previously been described in only two Australian colonies.

Efeitos de atrativos e repelentes sobre o comportamento da abelha (Apis mellifera, l.) Effect of attractants and repellents on the behavior of honey bees (Apis mellipera, L.)

open access: yesScientia Agricola, 1998
O objetivo do presente ensaio foi testar diversas substâncias e verificar sua atratividade e repelência para abelhas, Apis mellifera, L. Para isso, foram realizados testes em discos próximos às colméias e em cana picada oferecida como alimentação para ...

Negative ecological impacts of honeybees begin at densities below recommended levels for crop pollination

open access: yesJournal of Applied Ecology, EarlyView.
The ecological consequences of high‐density honeybee management are significant, calling for a re‐evaluation of pollination strategies in agricultural landscapes. Setting evidence‐based hive density guidelines is critical to balancing agricultural productivity with the conservation of native pollinator communities and the maintenance of healthy ...

Reproduction of Varroa destructor in sealed worker bee brood cells of Apis mellifera carnica and Apis mellifera syriaca in Jordan [PDF]

open access: yes, 2008
The reproduction of the honey bee mite, Varroa destructor in sealed worker bee brood cells represents an important factor for the population development of this parasite in honey bee colonies.

The Modified Pharaoh Approach: Stingless bees mummify beetle parasites alive [PDF]

open access: yes, 2008
Social insect colonies usually live in nests, which are often invaded by parasitic species^1^. Workers from these colonies use different defence strategies to combat invaders^1^.

More than fruity scents: Pollination biology, scent, and spectral reflectance of Annonaceae species

open access: yesPlant Species Biology, EarlyView.
We characterised the floral visual and olfactory cues of numerous Annonaceae species and reported their pollinators. We further assessed the olfactory space of most Annonaceae species available in the literature. Abstract The family Annonaceae possesses a broad array of floral phenotypes and pollination specializations, and are important in the plant ...

Effects of Flight on Gene Expression and Aging in the Honey Bee Brain and Flight Muscle [PDF]

open access: yes, 2012
Honey bees move through a series of in-hive tasks (e.g., “nursing”) to outside tasks (e.g., “foraging”) that are coincident with physiological changes and higher levels of metabolic activity.
