Phthiraptera: Sucking and Chewing Lice Flashcards
what type of lice are anoplura
sucking lice
what type of lice are mallophaga
chewing lice
What type of lice are amblycera, ischnocera, and rhynchophthirina?
chewing/biting lice
what type of parasites are wingless, dorsoventrally flattened, have reduced eyes (or none), and have tarsal claws often enlarged for clinging to hairs and feathers
lice
where to lice lay and cement eggs
at the base of feathers and hairs
how many nymphal instars do lice have
3
do lice have any free-living stages?
no
what type of lice can feed on feathers, hair, mucous, blood, and is often a vector for worms
chewing lice
what type of lice are small in size (other than laemobothrion circi) with a head that is usually broader than the prothorax
chewing lice
which of the chewing lice suborders is the most generalized and least host specific
amblycera
which lice suborder is more host specific and more limited in food preferences
ischonocera
rhynchophthirina is made up of haematomyzus elephantis and affects which two animals
elephants and warthogs
what animals are most chewing lice parasites of
birds
what amblyceran is the shaft louse of fowl
menopon gallinae
which amblyceran is the yellow body louse of chickens and turkeys
menacanthus stramineus
what lice are found in lightly feathered areas in high numbers – they gnaw through skin to reach the quill of pinfeathers and the irritation causes restlessness and disrupts feeding (this stunts development and causes decreases in egg production
menacanthus stramineus
this ischnoceran parasite causes extreme irritation in cattle – they rub themselves on solid objects and bite at their skin, which causes abrasians and hair loss
they are reddish brown in color
bovicola bovis
this ischnoceran parasite can be severe in puppies and serve as an intermediate host for dipylidium caninum (the egg packet parasite)
trichodectes canis
when host switching foes occur in chewing lice, what is it most commonly between
hosts of similar sizes
which type of lice has fewer than 500 species, parasitizes only mammals, are more specialized and medically important in humans, and has veterinary importance
sucking lice
what lice have heads that are narrower than the prothorax, mouthparts are retracted when not feeding, legs have a single tarsal claw for clinging to hairs, and eyes (if present) are small
sucking lice
what is it called when mouthparts are introduced into a vessel to withdraw blood
solenophage
what is it called when mouthparts cut through the skin and vessels to produce and feed from a pool of blood
telmophage
what are small wingless bugs that feed on the blood of warm-blooded animals (bedbugs)
cimicidae
