Q

What is the Ovipositor?

A

Egg laying device

17
Q

What are the 3 regions of the disestive system?

A
  • Foregut
  • Midgut
  • Hindgut
18
Q

Insect circulatory system is an Open System….what does that mean?

A

It’s Open….the hymolymph (insect blood) is free inside the body cavity. when the insect moves, the muscles contracting make the hemolymph move around inside.

19
Q

What are the primary functions of the insect Circulatory System?

A
  • Pressure regulation
  • Heat transfer
  • Food and waste transport
  • Storage
20
Q

What is the name for “insect blood” ?

A

hemolymph

21
Q

Describe the insect respiratory system.

A
  • One big lung
  • a series of tubes
  • Spiracles that open to the outside (one at each segment)
  • Oxygen diffuses in
  • Carbon dioxide diffuses out
  • When the movement pumps the hemolymph around, it “breaths”
22
Q

describe the methods of reprodution.

A
  • Parthenogenesis: Females will lay eggs without being fertilized.
  • Copulation: Takes male and female to reproduce
23
Q

What is the sack that holds all of the sperm?

A

Spermathecea

24
Q

Define Molting:

A

The process of digesting the old exoskeleton and synthesizing a new one

25
Q

A

Ecdysis

26
Q

What does the horomone Ecdysone do?

A

it stimulates apolysis (the seraration of the old cuticle from the underlying epidermis)

27
Q

What are instars?

A

The stages beweeen ecdysis

28
Q

what are the 3 developmental stages of simple metamorphosis?

A
  • Egg
  • Nymph
  • Adult
29
Q

What are the 3 types os simple metamorphosis?

A

  • Paurometabolous
  • Hemimetabolous
30
Q

Describe Ametabolous:

A
  • wingless as adults
  • no obvious difference besides size
31
Q

Describe Hemimetabolous:

A
  • “incomplete” metamorphosis
  • nymphs called niads
  • nymphs are aquatic and have gills
  • Very different from adults

think “H” H2o…water….

32
Q

Describe Paurometabolous

A
  • “gradual” metamorphosis
  • Adults have wings
  • Nymphs and Adults live in the same habitat
33
Q

Describe Holometabolous

A
  • Complete metamorphosis
  • Egg-Larvae-pupae-adult
  • Larvae and adults often live in different habitats and have different purpose
34
Q
