Q

Incomplete metamorphosis - The immature stage inhabits in water and are called naiad. Wings appear as buds (wing pad) on the early instars. When the last molt is completed the wings expand to the full adult size.

Q

Incomplete metamorphosis
- The immature stage inhabits in terrestrially and are called nymphs. Insect young are usually similar to the adult. Wings appear as buds on the nymphs or early instars. When the last molt is completed the wings expand to the full adult size.

19
Q

Can be define as the number of broods or generations produced in a year in the life cycle of an organism under natural conditions.

A

Voltinism

20
Q

This insects hatch one a year, so have one generation per year.

A

Univoltine

21
Q

This insect hatch twice a year, thus having two generations per year.

A

Bivoltine

22
Q

These insects can hatch several eggs in a year, so may have multiple generations per year.

A

Multivoltine

23
Q

It is the process which the body changes food and drink into energy

A

Metabolism

24
Q

What are the two processes of metabolism

A
  1. Catabolism
  2. Anabolism
25
Q

Involves the enzymatic degradation of large nutrient molecules from an organism reserved or from the environment

A

Catabolism

26
Q

Is the enzymatic synthesis of large cell components from small precursors

A

Anabolism

27
Q

What are the 3 sources of Enzyme

A
  1. Salivary Glands
  2. Digestive enzyme of the midgut
  3. Microorganisms
27
Q

The final stages of chemical digestion of the
food occur within the cells of the ________

A

Midgut

28
Q

the structural component of plant cell walls, is an un-branched glucose polymer

A

The larvae of Hypoderma (Diptera) & some blowflies are known to secrete a ___________
the collagen of animal tissues.

A

Collagenase

40
Q

maintains the internal environment of the insect by separating and eliminating metabolic wastes and other toxic substances from body compartments.

A

Excretory system

41
