25
what body system is most dorsal in arthropods?
blood
26
which body system is most ventral in arthropods?
nervous
27
how do arthropods breathe?
through holes(spiracles/stigmata) in their body
28
arachnids breathe through
stigmata holes in their body- similar to spiracles of arthropods
29
incomplete life cycle is also called
heterometabolous nymphs look like adult
30
complete life cycle of arthropods is also called
holometabolous larva look different from adult
31
heterometabolous lifecycle
nymphs look like adult- go through molts same habitat and feeding habits as adult life cycles occur on host
32
Holometabolous life cycle
egg- larva- pupa- adult larvae live in different habitat from adult have different feeding habits from adults adults suck fluid, larvae use mandibles to ingest particulates complete life cycle of arthropods
33
in a holometabolous life cycle, --- suck fluid and --- use mandibles to ingest particulates
complete life cycle adult larvae
34
acarine life cycle
hemimetabolous (incomplete) larvae have 6 legs nymphs- 8 legs and sexually immature adult
35
hemimetabolous life cycle
acarine life cycle- incomplete egg- 6 legged larvae- 8 leg nymph- adult
36
--- are examples of physical and chemical barriers to pest
fly traps nets repellants
37
--- are examples of environmental manipulation to control pest
bush clearing pasture spelling
38
--- are biological measures for pest managment
predators- birds microbial agents- viruses parasitoids- larva that eat insects
39
--- are larva that eat insects
parasitoids
40
the study of arthropods that impact the health of various animal species
veterinary entomology
41
ectoparasites that do not need the host to complete their life cycle
facultative
42
ectoparasites that are completely dependent on their host
obligatory
43
phenotypic adaptibility to different environment
genetic plasticity
44
the nerve cord of bugs is ventral or dorsal?
ventral
45
chilopoda
are the centipedes. Some species envenomize by means of hollow fangs
46
diplopoda
are the millipedes irritating toxins
47
direct role in disease causation by bugs
annoyance and blood loss dermatosis myiasis allergy envenomization
48
indirect role in disease causation of bugs
passive mechanical carriers intermediate hosts (biological or mechanical vectors)
49
integument comprises multilayered --- which is secreted by an underlying single-cell layer of ----.
cuticle epidermis
50
Cuticle contains ---, proteins, lipids and pigments and may be sclerotized (hardened)
chitin
51
respiratory tract of bugs are a profuse network of ---- and ---
trachea tracheoles
52
tracheae terminates as small openings on the cuticle called --- (in insects) or --- (in mites and ticks)
spiracles stigmata
53
gas exchange occurs via the spiracles and stigmata OR by ---across the cuticle
diffusion
54
continuous with hindgut lumen; remove nitrogenous wastes from hemolymph (blood) and void into hindgut
Malpighian tubules
55
females bugs have --- ovaries which are linked (by an oviduct) to an ---
paired ovipositor.
56
female insect tract has --- which stored sperm may remain viable for long periods.
spermatheca
57
insect sperm is enclosed in a packet of secretion called ----
spermatophore
58
mites and ticks go through what type of life cycle
incomplete hemimetabolous egg- 6 legs larva- 8 leg nymph- adult
59
two type of life cycles for insects
heterometabolous- incomplete/simple- egg- nymph- adult holometabolous- complete egg- larva- pupa- adults
60
IPM
integrated pest management
61
ecosystem-based approach for long-term prevention of pests by maintenance of their population at a level below the threshold for pathogen transmission.
IPM integrated pest managment
62
4 types of integrated pest management
physical and chemical barriers environmental manipulation chemical pesticides biological measures
