Module 4 Insect Anatomy Flashcards
1
Q
3 body segments
A
- head - antennae, eyes, mouthparts
- thorax - legs, wings
- abdomen - respiratory, reproductive, digestive
2
Q
functions of cuticle (exoskeleton)
A
- physical protection
- prevents water loss
- rigid surface for muscle/organ attachment
- sensory interface for hairs/spines
3
Q
resilin
A
rubber-like protein in exoskeleton that acts like springs (i.e. fleas)
4
Q
arthrodial membrane
A
unhardened cuticle between segments that allows for expansion as insects feed
5
Q
spine
A
cuticular extension
multicellular specialized
6
Q
seate
A
cuticular extension, sensory hair, multicellular
7
Q
acanthae
A
unicellular cuticular extension
8
Q
microtrichia
A
cuticular extension, few to many per cell
9
Q
chewing mouthparts
A
- labrum - upper lip, covers mandible
- hypopharynx - tongue
- mandibles - crush food
- maxillae - hold food
- labium - lower lip
10
Q
sucking mouthparts
A
- labrum - forms food channel
- hypo pharynx - forms salivary tube
- mandibles - pierce skin
- maxillae - pierces skin
- labium - sheath
11
Q
telmophages
A
pool feeders
cut skin then feed from blood pool
(i.e. deer flies)
12
Q
solenophages
A
vessel feeders
penetrate capillaries then feed directly on blood
(i.e. mosquito)
13
Q
parts of antennae
A
- scape - basal stalk
- pedicle - Johnston’s organ, sound-reception organ
- flagellum - remainder of antennae
- chemical receptors
14
Q
antennae types
A
- filiform - cockroaches
- moniliform - termites
- clavate, serrate, pectinate, flagellate - beetle
- geniculate - ants
- plumose - mosquitoes
- aristate - fly
15
Q
segments of thorax
A
- prothorax
- mesothorax
- metathorax
