Q

Involved in the exchange of gases between the cellular and external environment of
insects.
• It does not rely on an oxygen transport pigment (hemoglobin) and does not use the
circulatory system as the vehicle for gaseous exchange

16
Q

The only conducting vessel; a vessel situated along
the median dorsal line just beneath the integument

A

Dorsal vessel

17
Q

region with valves or ostia; in abdomen; pumping

A

Heart

18
Q

basically a tube; in thorax and head; conducting
vessel

A

Aorta

19
Q

a valvular opening which allow the hemolymph to enter
(incurrent ostia) or exit (excurrent) from the heart

A

Ostia

20
Q

– aid the movement of hemolymph in
addition to the pumping activities of the heart. They are concerned
with maintaining a circulation through the appendages

A

Accessory pulsatile organ

21
Q

The hemocoel or body cavity particularly
in the abdomen is usually separated into 2 or sometimes 3 cavities
or sinuses. These compartmentalization is produced by the
processes of one or two fribromuscular septa.

A

Sinuses and diaphragm

22
Q

eggs are produced

A

Ovarioles

23
Q

– storage for sperms

A

Spermatheca

24
Q

channel through which eggs are
discharge to unite the sperm

A

Oviduct

25
Q

– external opening of the reproductive
organ

A

Gonopore

26
Q

– the terminal portion of the female
reproductive organ; an egg holding chamber which
opens directly into the external ovipositor (egg
laying devise)

A

Vigina

27
Q

colleterial glands that secrete
adhesive materials used to cover or glue eggs
together

A

Accessory glands

28
Q

Female Reproductive System functions

A
  1. Produce and store eggs
  2. Provides the eggs with the necessary nutrients for
    embryonic development
  3. Receive and store spermatozoa
  4. Site of fertilization
  5. Deposits eggs or larvae
29
Q

production of spermatozoa

A

Testes/testis

30
Q

seminal duct from the sperm tube to
the vas deferens

A

Vas efferens

31
Q

seminal duct from the vas efferens to
the seminal vesicle

A

Vas deferens

32
Q

spermatozoa reservoir

A

Seminal vesicle

33
Q

– is for coating and protecting sperms
from acidity

A

Accessory glands

34
Q

spermatozoa duct or ejaculating
duct

A

Ejaculatory duct

35
Q

penis of a male insect

A

Phallus

36
Q

opening of the phallus

A

Gonopore

37
Q

Male reproductive system functions

A
  1. production, storage and delivery of spermatozoa
  2. Production of seminal fluid
  3. Provides the female with either chemical or physical
    signal to tell her that she had been mated
  4. Incidental function, to supply the female nutrients
    which can be incorporated into the developing oocytes
38
Q

Mating process

A

Courtship ritual
Mating
Fertilization
Oviposition
