Q

What legs of the honeybee are highly specialised for pollen collection?

A

Hind legs

24
Q

What is the outer surface of the tibia equipped with?

A

Corbicula

25
Q

How many segments is the abdomen made up of?

A

7 visible segments and 2 smaller segments for the sting in workers and reproductive organs in queens and drones

26
Q

What type of circulation system do honeybees have?

A

Open circulatory system

27
Q

What are the honeybees internal organs suspended in?

A

Haemolymph

28
Q

True or False?
Bees do not have lungs.

A

True
They have trachae

29
Q

What connects the trachae to the external environment?

A

Spiracles

30
Q

Where does digestion/absorption take place in the honeybee?

A

midgut

31
Q

What do worker bees have glands for?

A

Wax production, Defence, Food processing, Communication

32
Q

Where are the hypopharyngeal glands located?

A

behind the face

33
Q

What is the function of the hypopharyngeal glands?

A

Produce brood food
(proteins,lipids and vitamins)

34
Q

What is the function of the nasonov gland?

A

Produces a scent used for orientation

35
Q

True or false?
only male bees have the venom gland

A

False

Only female bees have the venom gland. The workers sting is barbed and the queens is not hence why only the workers die when they sting.

36
Q

What is the lifespan of worker bees?

A

~ 4-6 weeks if born in the summer and 4-5 months if born in the winter

37
Q

True or False?
Generally younger bees do jobs in the nest and older bees do jobs outside the nest.

A

True

38
Q

What jobs do younger bees (1-10 days) do?

A

Cell cleaning, feed brood, tend to the queen, cap brood

39
Q

What jobs do middle aged bees (10-20 days) do?

A

Comb construction, pollen/nectar handling, hive cleaning, ventilation

40
Q

What jobs do older bees (20+ days) do?

A

Guard duty, hive defence, foraging

41
Q

What is the one significant function that drones are designed for?

A

Mating

42
Q

Why are new queens raised?

A

. The colony is too big and needs to swarm
. The old queen is running out of sperm (supercedure)

43
Q

How many drones does the queen mate with?

A

7 - 17 drones

44
Q

What caste is produced from unfertilised eggs in larger cells?

A

Drones

45
Q

What caste is produced from fertilised eggs in smaller cells?

A

Workers

46
Q

What 3 requirements that are needed to produce a queen?

A
  1. Fertilised egg raised in a queen cup
  2. fed royal jelly
  3. fed more
47
Q

What are the 4 stages of the life cycle of a honeybee?

A

Egg -> Larvae -> Pupae -> Adult

48
Q

How long does it take for each caste to develop?

A

Oueen: 16 days
Worker: 21 days
Drone: 24 days

49
Q

When was the first evidence of beekeeping seen?

A

2,400 BCE

50
Q

What is the name for a traditional beehive?

A

Skep

51
Q

What are 2 problems associated with hives with fixed combs?

A

Difficult to inspect the colony

Difficult to harvest the honey

52
Q

Why are the invention of the different chambers (honey supers and brood chambers) efficient?

A

Honey can be removed more easily without damaging the brood

53
Q

What happens in Autumn in accordance to the beekeeping calender?

A

Colony maintenance, Conserve food, Reduce brood, death of drones

54
Q

What happens in Winter in accordance to the beekeeping calander?

A

Maintain temperature and conserve food

55
Q

What occurs in spring in accordance to the beekeeping calander?

A

Increase brood and start foraging

56
Q

What happens in summer in accordance to the beekeeping calander?

A

Foraging, brood production, comb production, swarming and queen mating

57
Q

What is swarming?

A

Natural process by which honeybee colonies form a new colony
