6. Important for studying social evolution, learning and memory

Question 10

How do “Apis Mellifera” communicate?

Answer 10

Through pheromones and dance language

Question 11

What causes the differences in behavior and physiology between castes in “Apis Mellifera”?

Answer 11

Differences in gene expression

Question 12

Describe the caste of Drones in “Apis Mellifera”.

Answer 12

1. They are male honey bees, without stinger
2. They don’t gather nectar or pollen
3. They are products of unfertilized eggs
4. Sole purpose is to mate with queen
5. Mating lasts five seconds then die
6. Life expectancy is 90 days

Question 13

Describe the caste of Workers in “Apis Mellifera”.

Answer 13

1. Produced from fertilized diploid eggs
2. Essential for social structure and colony function
3. They raise sisters and future queens (sterile)
4. They forage for nectar/pollen to bring back
5. Larvae workers are fed “bee bread”
6. Life span is 5-6 weeks

Question 14

Describe the caste of Queens in “Apis Mellifera”.

Answer 14

1. Larger with developed reproductive system
2. Queens are chosen at larvae stage and fed royal jelly throughout development
3. They develop in compartments called “queen cups
4. Virgin queens fly out when the weather is good and mate with 12-15 drones
5. Stores the six million sperm for her five years of life
6. Sole function is a reproducer

Question 15

What happens during the spring in the annual cycle of a honey bee colony?

Answer 15

The queen lays fertilized eggs to grow the workforce.

Question 16

What happens during the early summer in the annual cycle of a honey bee colony?

Answer 16

Bee numbers and activity are high, and the workers are foraging on plentiful resources.

Since there is an increased food supply, and population swarming begins

Question 17

What happens during the late summer in the annual cycle of a honey bee colony?

Answer 17

The workers construct specialized cells where the new queens will emerge

Before the new queens emerge, the old queen, some workers, and some drones leave the hive

Scout workers search for a new place to live and dance to communicate where the new place is

Once the new hive is established, the old queen begins to restore the population

Question 18

What happens during the late fall in the annual cycle of a honey bee colony?

Answer 18

Reproduction halts as resources become limited and drones are expelled

The remaining colony clusters together on honey filled combs during winter, and their bussing keeps them warm

Question 19

Describe the life cycle of a queen in more detail.

Answer 19

1. After the specialized cells have been made and the larvae fed royal jelly, the new queens emerge and fight for dominance
2. The remaining pupal queens are destroyed by workers
3. A surviving queen takes flights for several days to mate with drones from other hives
4. Returns to the hive and reproduces the rest of her life

Question 20

Describe dance language.

Answer 20

1. The direction the bee moves in relation to the hive communicates the direction on flowers in relation to the sun
2. The duration of the waggle tells how far the flowers are (1sec = 1km)

Question 21

How much of the food we eat depends directly on insect pollination?

Answer 21

1/3

Question 22

Why can transporting bees be an issue?

Answer 22

Makes bees more susceptible to

1. Mites
2. Viruses
3. Non-diverse foraging
4. Extreme temps
5. Pesticides

Question 23
