25
intermediate hosts
harbors asexual, immature, or larval stage
26
Reservoir or alternate hosts
final host that harbors the infection but show no sign of infection
27
unnatural host in which parasites are accidentally lodged and transmission is through ingestion of paratenic host
Transport or Paratenic host
28
Free living in nature can become parasitic in certain host
facultative
29
must lead a parasitic existence
obligatory parasites
30
pseudoparasite
mistaken to be parasite
31
From infection until egg is demonstrated
Prepatent period
32
From egg production by adults until it ceases
patent period
33
any association between at least two living organisms of different species
symbiosis
34
member of symbiosis is called
symbiont
35
both organisms in the symbiotic relationship benefit
mutualism
36
samples of mutualism
1. Ruminant Microflora 2. flagellate and wood termite
37
commensalism
only one symbiont is benefitted although the other neither benefits nor is harmed
38
Predator - prey
An extremely short-term relationship in which one symbiont benefits at the expense of the other
39
Phoresis
Smaller member of the symbiotic relationship is mechanically carried about by the larger member
40
One symbiont (parasite) lives on or within the other member (host) and may cause harm
parasitism
41
Oviparous
lays undeveloped eggs
42
Ovoviviparous
lays larvated egg
43
Larviparous
lays larva
44
Pupiparous
lays larva that immediately turns into pupa
45
Parthenogenetic
reproduce without fertilization (male)
46
last larval skin retained; hardened skin (puparium) encloses pupa hence it can not be seen externally
coarctate
47
wings and legs bound to body by molting fluid but still visible externally
obtectate
48
wings and legs free from body and can be seen externally
exarate
49
with no legs on the thorax and abdomen (no legs)
Apodous
50
with head, 3 pairs of thoracic legs but no abdominal legs
Oligopod
51
with head,3-segmented thorax with legs and abdominal legs (complete)
polypod
52
Instar
form of the stadium
53
Stadia
stages between molts
54
