egg
contains embryo
cytoplasm + nucleus + yolk
divides many times
cleavage cells become the blastoderm
larva
5 instars (sub-stages)
moulting
fed royal jelly by nurse bees 1st 3 days after hatching
bee bread
pollen and nectar
fed to workers and drones
queens diet
continue to get fed royal jelly past the 3 day mark
pupa
metamorphosis (develop into adults)
ecydysone and juvenile hormone
ecdysone
regulates moulting
juvenile hormone
influences cell division and body differentiation
exoskeleton
composed of hardened plates
protection, support, attachment for organs and muscles, prevents dehydration
3 body segments
head, thorax, abdomen
head
contains sensory and digestive structurea
eyes
3 ocelli
2 compound eyes
ocelli
detect light intensity and may serve for orientation during flight
compound eyes
create images to recognize motion or used for colour vision
mosaic composed images
antennae
sense organs detect odours, CO2, humidity, flavours, temperature, airflow
Johnston organ
mouthparts
mandibles and proboscis
mandibles
cut, shape, groom, fight
proboscis
ingestion of liquids
thorax
prothorax, mesothorax, metathorax
3 pairs of legs
2 pairs of wings
legs
coxa, trocanter, femur, tibia, tarsus
arolium
allow bees to walk on rough or flat surfaces
distal part of the tarsus
fore legs
have antenna cleaner
hind legs
pollen and propolis packing
corbicula (basket)
used to pack and carry pollen or propolis pellets
on the tibia
basitarsus
pollen brush and pollen rake used for pollen and propolis
hair
branched to carry pollen grains
wings
have veins that serve as support and for blood circulation
hooked together by hamuli
flight
24km/h
200 cycles/s
honey stomach (crop)
nectar transport
ventriculus
secrete enzymes for digestion and absorption
malpighian tubules
blood filters
discard waste
blood
blood cells and plasma
circulatory
open
respiratory
tubes and tubules connected to body by spiracles
nervous system
brain, 2 ventral nerve cords, 7 ganglia and nerves
defense
ovipositor made of 3-piece shadt attached to venom sac
2 barbed lancets and a stylet with poison canal
drones dont have stinger
queens stinger is not barbed
wax glands
4 pairs on 4th and 7th abdominal segments
hardens into scales to be used for comb construction
nasonov gland
7th abdominal tergum
produces attractive scent
orients bees to hive, swarm cluster, flowers
mandible glands
nurse bees
10-hydroxi-2-decenoic acid (lipid for larval food)
2-heptanone (alarm pheromone)
queen substance (colony recognition, drone attraction, foraging stimulation)
sting glands
alarm pheromone (IPA)
arnhart glands
foot print substance
salivary glands
produce saliva to dissolves sugars and soften pollen grains
hypopharingeal glands
produce royal jelly
drone reproductive organs
penis, testes, seminal vesicles, mucus glands, ducts
queen reproductive organs
2 large ovaries, 150 ovarioles, oviducts, vagina
