Fanning Trial Review
Is using your phone or listening to music allowed during a fanning trial?
NO, NEVER
What was the main question in the experience paper?
Whether the presence of an experience individual influences other inexperienced honey bees within the collective group fanning response
What are the four biogenic amines that play a significant role in honeybee division of labor?
Dopamine, octopamine, serotonin, tyramine
Besides fanning, foraging, and nursing, what other tasks do honeybees perform in the hive?
undertaking, guarding
What is the relationship between group size and the rate of fanning?
Larger groups are more likely to fan.
What is the rate of increase should you ramp the temperature of the hotplate?
1C/min
What is the main hypothesis of the experience paper?
The presence of a fanner would influence the individual fanning response threshold of a nurse
What is a biogenic amine?
A type neurotransmitter that has one or more amine groups
Define division of labor (bonus points if you can define division of labor in terms of eusocial insects)
task allocation; certain individuals reproduce while all others accomplish other tasks in the colony
Define the behavior of a fanning honeybee
Standing still for at least 10sec, abdomen curved down, wings flapping, head towards the entrance of the hives
You're setting up a fanning trial. You notice that the hot plate you were going to put your jar on still says "HOT" and the jar that was on it was still warm. What should you do in this case for acclimation?
Acclimate bees OFF the hotplate in a new cool jar
Which group is more likely to fan, a group of fanners or a group of nurses?
fanners
What was the hypothesis of the neurotransmitter paper?
The inclination to fan was correlated with neurotransmitter concentration among similarly aged individuals
Why would individual behavioral variation be beneficial to an animal group?
Allows flexibility and adaptability to a changing environment
Should you record nasanov fanning?
Yes, but mark it separately
How do you calculate ramp rate after a trial has ended?
start temp - end temp / total trial duration
How did the experimenters keep track of who was a fanner and who was a nurse bee?
What is the relationship between fanning and octopamine and tyramine specifically?
Octopamine and tyramine DECREASE when fanning occurs
Why do bees fan?
To regulate temperature, CO2 and humidity
When looking at SURVEYOR during a trial, what range of temperature increase would indicate to you that you should not continue to ramp the hot plate?
0.3-0.4 or higher
True or false? The presence of fanners increased the thermal threshold of nurses
True
True or false? Feeding octopamine and tyramine to bees increased the probability that a bee fanned
false
Why did the experimenters deem nurses as 'inexperienced' and fanners as 'experienced' individuals?
Explain the best way to collect a bee from the hive entrance.
Approach the bee from behind, not slow or fast. If you are using the soft forceps, try and grab the whole bee. If using hard forceps, grab the leg only.
