1. Behavioral performance in adult honey bees is influenced by the temperature experienced during their pupal development
To investigate the possible consequences of brood-temperature regulation in honey bee colonies on the quality of behavioral performance of adults, we placed honey bee pupae in incubators and allowed them to develop at temperatures held constant at 32°C, 34.5°C, and 36°C. This temperature range occurs naturally within hives. On emergence, the young adu

2. Seasonal population abundance of the assembly of solitary wasps and bees (Hymenoptera) according to land-use in Maranhão state, Brazil
ABSTRACT Solitary wasps and bees (Hymenoptera) play a key role in ecosystem and agroecosystem functioning. Crops may benefit from biological pest control and pollination carried out by predatory solitary wasps and solitary bees, respectively. Here, we aimed at evaluating the abundance and faunistic compositions of solitary wasps and bees in respect to land-u

3. Multiple origins of advanced eusociality in bees inferred from mitochondrial DNA sequences.
The remarkably high level of colony organization found in the honey bees and stingless bees (family Apidae) is extremely rare among animals. Yet there is controversy over whether these two groups independently evolved advanced eusocial behavior or inherited it from a common ancestor. Phylogenetic analyses of DNA sequence information from the mitochondrial ge

4. Kin discrimination by worker honey bees in genetically mixed groups
We tested the hypothesis that in a genetically mixed assemblage of worker honey bees, individual workers would behave differently toward unfamiliar sisters than toward unfamiliar nonsisters. Groups of worker honey bees of mixed genetic composition were assembled by collecting pupae from separate colonies and placing the worker bees together on eclosion. A to

5. Comb wax mediates the acquisition of nest-mate recognition cues in honey bees
Honey bees, Apis mellifera, acquire nest-mate recognition cues from wax, the predominant material used in nest construction. Exposure of a newly emerged worker bee to wax-comb substrate significantly reduced the acceptability of that worker to sister bees. Cues acquired from the comb provided colony-specific information about the identity of worker bees; mor

7. Bees Diversity on Flowers of Eremanthus spp. (Asteraceae)
ABSTRACT Bees are considered important pollinators due to their fidelity to plants, enabling the maintenance of gene flow between plant species. The objective of this study was to recognize the visit of bees in two Candeia species, Eremanthus erythropappus and Eremanthus incanus (Asteraceae), as well as to analyze the pollen content carried by bees in a rege

8. DNA differences found between Africanized and European honeybees.
The harmful en masse introduction of Africanized honeybees into the United States will occur within 5 years. Possible means of control are dependent on a reliable way to distinguish the Africanized bees from the extant European bees. Current means of identification are inadequate. Reported here are the encouraging initial results to distinguish the bees by t

9. Honey bees navigate according to a map-like spatial memory
By using harmonic radar, we report the complete flight paths of displaced bees. Test bees forage at a feeder or are recruited by a waggle dance indicating the feeder. The flights are recorded after the bees are captured when leaving the hive or the feeder and are released at an unexpected release site. A sequence of behavioral routines become apparent: (i) i

10. Dual origin of highly social behavior among bees.
A study of behavior and structure indicates that highly eusocial behavior arose twice in the bees--i.e., in the stingless bees (Meliponinae) and in the honeybees (Apinae). Morphological features demonstrate the distinctiveness of these two groups and the relationship of the latter to bumblebees (Bombini) and orchid bees (Euglossin). The social behaviors of t

11. Analysis of community structure of bees (Hymenoptera:apoidea) in an area of Caatinga do de BaturitÃ, CearÃ, Brazil / AnÃlises da estrutura da comunidade de abelhas (Hymenoptera: Apoidea) em uma Ãrea de caatinga do MaciÃo de BaturitÃ, CearÃ, Brasil
The great importance of bees as pollinators of several plant species has stimulated many investigations carried out on the organization and structure of their community. This type of study consist of describe the composition, abundance, richness, diversity, temporal variation of bees and their relationship with plants. The object of this study was to know th

12. Distribution of Kakugo Virus and Its Effects on the Gene Expression Profile in the Brain of the Worker Honeybee Apis mellifera L.▿ †
We previously identified a novel insect picorna-like virus, termed Kakugo virus (KV), obtained from the brains of aggressive honeybee worker bees that had counterattacked giant hornets. Here we examined the tissue distribution of KV and alterations of gene expression profiles in the brains of KV-infected worker bees to analyze possible effects of KV infectio
