Behavioural mimicry of honeybees ( Apis mellifera ) by droneflies (Diptera: Syrphidae: Eristalis spp.)

The mimicry of honeybees (Apis mellifera) by droneflies

(Eristalis spp.) has been fooling humans for thousands of years (Atkins, 1948). The important question in considering whether it is a true case of Batesian mimicry, however, is whether it fools their predators, which are thought to be birds. Eristalis spp. are not considered to be the best visual mimics of honeybees; other British hoverflies such as Mallota cimbiciformis (Fallén), Criorhina asi...

Virus 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...

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...

Simultaneous 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...
