Honey bee workers from a colony in North Carolina are visiting two food sites, A and B, at 6 am as shown below. Site A is 1500 m from the hive; site B is 300 m from the hive. While most of the foragers are out in the field, a sudden downpour strikes which drowns many of the bees outside the hive. As a result, there is a shortage of foragers in the nest at a time when much food is available in the field. Which of the following can you correctly predict will happen: a. The loss of foragers will cause increased activity of the Gp9 gene in some of the bees inside the nest, which will decrease their JH levels, causing them to revert to nursing behavior and raise more brood to quickly replace the lost foragers. b. The loss of foragers will result in decreased transfer of ethyl oleate to the younger bees, which will cause JH titers in some of the younger bees to increase and they will become precocious foragers. c. The loss of contact with older bees will cause increased Amfor and per activity in some young bees such that they initiate foraging behavior and have active biological clocks sooner than normal. d. The loss of contact with older foragers will cause some of the younger bees to perform vibration signals, which will lower JH production in recipients, causing them to revert to brood care to replace the lost workers. e. a & d would happen f. b & c would happen

Question

Honey bee workers from a colony in North Carolina are visiting two food sites, A and B, at 6 am as shown below. Site A is 1500 m from the hive; site B is 300 m from the hive.

While most of the foragers are out in the field, a sudden downpour strikes which drowns many of the bees outside the hive. As a result, there is a shortage of foragers in the nest at a time when much food is available in the field. Which of the following can you correctly predict will happen:

a. The loss of foragers will cause increased activity of the Gp9 gene in some of the bees inside the nest, which will decrease their JH levels, causing them to revert to nursing behavior and raise more brood to quickly replace the lost foragers.

b. The loss of foragers will result in decreased transfer of ethyl oleate to the younger bees, which will cause JH titers in some of the younger bees to increase and they will become precocious foragers.

c. The loss of contact with older bees will cause increased Amfor and per activity in some young bees such that they initiate foraging behavior and have active biological clocks sooner than normal.

d. The loss of contact with older foragers will cause some of the younger bees to perform vibration signals, which will lower JH production in recipients, causing them to revert to brood care to replace the lost workers.

e. a & d would happen

f. b & c would happen
