workers
26
how many pairs of wings do they have
2 pairs
27
mandible of drones
rudimentary
28
tasting of bees
no bitter
29
the honey crop
stores nectar without digesting it
30
proventriculus
AKA muscular valve closed to prevent nectar from passing into stomach
31
the true stomach
AKA ventriculus primary digestion site for pollen and nectar - twice the length of the bees body and is curled
32
the hindgut
composed of intestines and rectum
33
how many segments of digestive tube
7 1. pharynx - oesophagus 2. crop (honey vesicule) 3. valvula cardica 4. stomach 5. mid gut 6. hindgut 7. rectum
34
how many spiracles do bees have
3 pairs
35
how many chambers does a bee have in the heart
5 chambers plus an aorta
36
how many legs do bees have
3 pairs with appendices
37
how many legs do bees have
3 pairs with appendices
38
appendices of legs of bees
antenna cleaner claws adhesion discs pollen busket pollen press
39
what is pollen basket
is made of long stiff hairs that curve around a wide flattened section of the honeybee´s back leg
40
what is pollen press
is located just below the pollen basket on the hind legs
41
what is involved in the excretion system
malphigian bodies (150)
42
number of spiracles of trachea
10pairs
43
do bees have blood coagulation
no
44
composition of haemolymph
haemocytes, leucocytes, oenocytes
45
composition of nervous system
- Cerebrum and oesophageal neuron - ventral nerve cord, 7 ganglia
46
what kind of glands do larvae have
only labial/spinning glands so no hypopharyngeal glands
47
in which bees can you find hypopharyngeal glands
only in workers - most active in young bees to make royal jelly
48
what gland does the queen have
queen mandibular gland which - produces queen products - inhibit the development of worker ovaries - attract drones - stimulate foraging the brood rearing
49
purpose of rectal glands
regulation of water content of feces
50
what are nasonov/odour glands
signals location used by guard bees homing phermone
51
Dufour gland
only in females
52
Wax glands located on
Located on sternites 4, 5, 6 and 7
53
what is honeybees venom known as
apitoxin
54
what is the alarm pheromone
koschevnikov gland - released when a bee stings another animal to attract the other bees to the location
55
drone mandicular pheromone
attracts other flying drones to suitable site for mating with virgin queens
56
what is dufours gland pheromone
allows worker bees to distinguish b/w eggs laid by the queen
57
what is footprint pheromone
left by bees when they walk
58
what is forager pheromone
released by older forager bees to slow maturing of nurse bee
59
what is nasonov pheromone
emitted by works used for orientation and recruitment
60
what is ovipositor
a stinger on end of females abdomen
61
life cycle of a bee
holometamorphosis
62
what do diploid eggs become
queens or workers
63
when do drones and queens mate
in flight
64
when are sprematozoa released
to fertilize each mature eggs just before it is laid or not
65
6 phases of worker bee
1. Embryo develops for 3 days in the egg 2. Larva hatches from egg - 5 larval stages 3. fully grown larva spins a coccoon 4. propupae 5. Pupa, 6. adult emerges from its cell
66

16days
67
how long does it take for a worker to mature
21 days
68
