Simultaneous conditioning in honeybees (Apis mellifera).
Journal of Comparative Psychology, 1992Honeybees (Apis mellifera) were classically conditioned with odor as conditioned stimulus (CS), sucrose as unconditioned stimulus (US), and proboscis extension as response. The purpose of Experiment 1 (Ns = 26 and 27) was to look for facilitation of forward conditioning by CS-US overlap, but rapid conditioning without overlap left little room for ...

Ecology of Varroa destructor, the Major Ectoparasite of the Western Honey Bee, Apis mellifera.
Annual Review of Entomology, 2016Varroa destructor is the most important ectoparasite of Apis mellifera. This review addresses the interactions between the varroa mite, its environment, and the honey bee host, mediated by an impressive number of cues and signals, including ...

Alcohol dehydrogenase polymorphism in Apis mellifera
Biochemical Genetics, 1977A polymorphic system of ADH isozymes is described in the honeybee Apis mellifera. Three and six different electrophoretic patterns were found, respectively, in drone and worker pupae analysis. The data indicate that the ADH isozymes are controlled by three alleles, Adh-1(1), Adh-1(2), and Adh-1(3). The frequency of the Adh-1 alleles is different in two

[Taxonomy of Apis mellifera viruses].
Virologie (Montrouge, France), 2006With the exception of the filamentous virus, all viruses of the honey bee (Apis mellifera L.) are single stranded RNA viruses. At the time of their discovery, they have been classified as picorna-like viruses. Progress in molecular biology allowed sequencing some of them and revealed they were differed from picornaviruses. Two new taxons were therefore

Local honeybee (Apis mellifera mellifera L.) populations in the Urals
Russian Journal of Genetics, 2007The COI-COII intergenic region of mitochondrial DNA (mtDNA) was studied in local honeybee (Apis mellifera mellifera) L. populations from the Middle and Southern Urals. Analysis of bee colonies in these regions revealed apiaries enriched in families descending from A. m. mellifera in the maternal lineage.

Aversive conditioning in honeybees (Apis mellifera). [PDF]
Journal of Comparative Psychology, 1986 Learning in honeybees, previously studied by appetitive techniques, was studied here by aversive techniques. In one series of experiments, a shuttle box was used, with the odor of formic acid as the aversive stimulus. A punishment contingency was found to suppress shuttling more in master animals than in yoked controls, whereas escape and unsignaled ...

Delayed alternation in honeybees (Apis mellifera).
Journal of Comparative Psychology, 2003Previous experiments with honeybees (Apis mellifera) failed to show learned control of performance by short-ten memory. In this study, honeybees were trained with an improved technique to choose 1 of 2 colors that was either the same as a recently rewarded sample (perseveration) or different (alteration).

The Honeybee Apis mellifera L.
1990The biological [1, 2, 6, 11–18, 21, 22, 28, 29, 31, 38] and apicultural aspects [5, 25, 27, 42, 55] of the honeybee have been discussed in many publications.
