Acquisition and Extinction of a Shuttling Response in Honeybees (Apis mellifera) As a Function of the Probability of Reward
نویسندگان
چکیده
The effects of partial (intermittent) versus consistent reward on the acquisition and extinction of a shuttling response were studied in 3 experiments with foraging honeybees (Apis mellifera). Adding nonrewarded trials to rewarded trials (the equated-reinforcements design) improved performance in acquisition and increased resistance to extinction. Substituting nonrewarded trials for some rewarded trials (the equated-trials design), which had little effect on acquisition, also increased resistance to extinction but to a lesser extent than adding nonrewarded trials. Marked variations in the schedule of partial reward (the sequence of rewarded and nonrewarded trials) were without effect. The results are compared with those of analogous experiments on vertebrates.

Learning in Honeybees (Apis mellifera) as a Function of Amount of Reward: Acquisition Measures
Foraging honeybees (Apis mellifera) were trained individually to discriminate between targets that contained 5-/il or 20-̂ 1 drops of sucrose solution. Neither latency of response on singlestimulus trials nor preference on choice trials proved sufficiently sensitive to provide a detailed picture of the course of learning as a function of amount of reward, but measures of resistance to extinction...

Polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) and phylogenetic analysis were used for molecular identification of lactic acid bacteria (LABs) isolated from Apis mellifera. Eighteen honeybee workers were collected from three different apiaries in West Azerbaijan. LABs from the gut of honeybees were isolated and cultured using routine biochemical proce...
متن کاملMolecular mechanisms underlying formation of long-term reward memories and extinction memories in the honeybee (Apis mellifera).
The honeybee (Apis mellifera) has long served as an invertebrate model organism for reward learning and memory research. Its capacity for learning and memory formation is rooted in the ecological need to efficiently collect nectar and pollen during summer to ensure survival of the hive during winter. Foraging bees learn to associate a flower's characteristic features with a reward in a way that...

The first step in fundamental breeding of any living organism is the determination of its genetic make-up. To investigate the genetic make-up of the European honeybee (Apis mellifera L.) in Iran, some research attempts were made during the years 1992-1996 in which the bee's relationship with some exotic races were determined through the application of morphological methods. For this purpose 130...
