Q

How does flight temperature works?

A

By passing the excess heat to the head by means of passive conduction and accelerated blood flow
Excess heat is eliminated by regurgitating droplet of water-down honey - which cools the head much like a sweat in I vertebrates

25
What happens if sugar falls bellow 1%?
Bees can no longer fly
26
What are their fuel?
Workers engorge honey and stores it in their stomach before leaving nest , gradually consuming it during flight
27
How many legs?
3 pairs of legs = 6 legs
28
What's on the tip of their leg?
Taste receptors
29
What do they use to clean antennae?
Forelegs
30
Function of their middle leg.
Helps with walking and to pack loads of pollen
31
is the sticky resinous substance that the bees collet from the buds of trees and use to seal up cracks in the hive.
Propolis
32
Purpose propolis
Used for variety of nifty products
33
Hind legs are specialized in what type of bee?
Worker bees
34
These tiny holes along the sides of a bee's thorax and abdomen are the means by which a bee breathes.
Spiracles
35
Where does trachea attached?
Spiracles
36
What hole in the thorax that tracheal mites gain , access to the trachea?
1st hole
37
Saliva is mixed with__ to make it sticky
Bees wax
38
Nervous system comprises a:
Small brain and 7 ganglia ( the 7th is near the abdomen)
39
The air sacs are connected to the surface by
tracheal tube
40
Air sacs emerges near the wings for_
Breathing
41
What causes the distinctive buzz?
Rapid flapping of wings
42
At what mph that you can't outrun a honeybee?
15 mph
43
What is the use of the forelegs?
Antennae cleaners
44
What is the use of hindleg?
Pollen baskets or corbicula
45
Reproductive organ ave well-developed in
Queen bee
46
Wax and scent glands are present in
Worker bees
47
Abdomen contains:
Digestive organs, reproductive organs, way and scent glands and infamous stinger
48
Adult honey bee and larva have how many abdominal segments?
10
49
It is a crop or storage area to hold freshly collected nectar or water for transport to or from the nest
Honey stomach
50
Digestion of food occur in
Midgut
51
What is the purpose of hindgut?
Reclaims water and nutrients and passes small amount of indigestible wastes to the rectum for storage until excretion.
52
The abdomen of worker bees have how many abdominal segments?
7 visible segments
53
What is the first abdominal segment of worker bees?
Propodeum
54
There are actually_ abdominal segments
10 but the 8th, 9th, and 10th are hidden inside the 7th abdominal segment
55
It is the blood of bees
Haemolymph
56
Blood is not carried by arteries and veins but Flows around the body, through the dorsal and ventral diaphragm called
Vessels, bellows or heart
57
Oxygen enters the bee via
Spiracles then to the bellowsin the abdomen which distribute it into the blood,
58
Each abdominal segment constructed of...
One large dosas and one ventral plate
59
The two plates (dorsal and ventral) is connected by
Membranes to allow the abdomento expand when the stomach is engorged with nectar or water and also pumping of the abdomen for increase oxygen uptake.
60
It contains most of the organ systems and some glands
Abdomen
61
Where is the sting situated?
Abdomen
62
Abdomen is externally....
Hairy
63
The sting is made up of:
sting is made up of two barbed lancets below the stylet supported by hardened plates and strong muscles and connected to a poison and glands containing alarm substances.
64
It is highly modified ovipositor which evolved for its defensive function.
Sting
65
Sting has a large basal structure called
Bulb of stylet
66
is contained within a chamber at the end of the abdomen from which only its effective part, tapering, sharp-pointed shaft is protruded.
Sting
67
Sting has a solid structure shaft which is composed of the three separable pieces:
One above the stylet and two lancets below
68
What happens when bee stings the victim?
When the worker stings and the forward facing barbs catch hold in the skin, the worker then pulls away, ripping the sting out because of its 9 or 10 recurved barbs at the outer side near the end and dies within a few hours or days due to massive abdominal rapture
69
Venom is a mixture of
Proteins and peptides
70
What in the major component of protein in the venom
Melittin
71
Other components of venom
Hyaluronidase, phospholipase a, acid phosphates, and histamine
72
Three levels of reactions in humans by sting
Local, systemic, anaphylactic
73
localized swelling followed by more extensive swelling a Few hours later, affected area may become red, itchy and tender to 203 days.
Local reaction
74
- symptoms occur with seconds which include difficulty in breathing, confusion, vomiting and falling blood pressure which can lead to loss of consciousness and death from circulatory respiratory collapse. Resistance to bee stings may develop the more one isstung. Extremely sensitive individual may die from a single sting.
Anaphylactic reaction
75
occurs within few minutes of stinging which may involve a whole body rash, wheezing, nausea, vomiting, abdominal and fainting.
Systemic reaction
76
It causes cell lyses; pain, toxicity, synergistic with mellitin
Phospholipase A
77
It causes lyses ot blood and most cells; release of histamine and serotonin from mast cells, and depression of blood pressure and respiration
Mellitin
78
Hydrolyzes connective tissue called spreading factor since it opens up passages for other components; Nontoxic
Hyaluronidase
79
Itching pain; amount in venom much lower than toxic levels or amount released by mast cells
Histamine
80
Involved in allergic reaction
Acid phosphates
81
Wax production is used for
Comb construction
82
Beeswax is produced by
Modified epidermal cells located ventrally on the 4th to 7th abdominal segments
83
Best bee hive temp for wax secretionand manipulation in the bee hive is
35°C or 33 - 36°C
84
best beehive temperature for wax secretion and manipulation in the beehive is at
35°C (33-36°C).
85
The best beehive temperature for wax secretion and manipulation in the beehive is at
35°C (33-36°C).
86
Wax secreting cells_ when was is not being produced
Shrinks
87
Wax are removed by
Brushing the spines of the hind basitarsi on the mirrors
