Delayed alternation in honeybees (Apis mellifera).
Previous 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). Because any increase in associative strength stemming from the sample experience would ten...
متن کاملSimultaneous conditioning in honeybees (Apis mellifera).
Honeybees (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 improvement. In 2 further experiments, CS and US...
متن کاملMagnetoreception System in Honeybees (Apis mellifera)
Honeybees (Apis mellifera) undergo iron biomineralization, providing the basis for magnetoreception. We showed earlier the presence of superparamagnetic magnetite in iron granules formed in honeybees, and subscribed to the notion that external magnetic fields may cause expansion or contraction of the superparamagnetic particles in an orientation-specific manner, relaying the signal via cytoskel...
متن کاملVirus Infections of Honeybees Apis Mellifera
The health and vigour of honeybee colonies are threatened by numerous parasites (such as Varroa destructor and Nosema spp.) and pathogens, including viruses, bacteria, protozoa. Among honeybee pathogens, viruses are one of the major threats to the health and well-being of honeybees and cause serious concern for researchers and beekeepers. To tone down the threats posed by these invasive organis...
متن کاملSuperparamagnetic Magnetite in the Iron Granules of Honeybees (apis Mellifera)
Magnetoreception and iron biomineralization in honeybees (Apis mellifera) have been investigated for several decades. Numerous open questions are still been hotly debated, especially the location of superparamagnetic magnetite. To solve this argument, we use the size-density purification technique to purify the iron granules of trophocytes and determined their magnetic properties, which include...
