Veterinary Entomology (Book) Flashcards
Main body divisions are cephalothorax and abdomen and the legs are found on thoracic and abdominal segments
Parasitic crustaceans
Adults are warm like cylindrical without legs except two pairs of hooks near the mouth but larvae has with two pairs of legs
Pentastomida or the tongue worms
They are adults with three pairs of legs, body divided into three main parts the head the thorax and the abdomen
Parasitic insects such as mosquitoes flies and lice
Their body parts are joined together, the adults with four pairs of legs two pairs of mouth parts without antenna and wings
Parasitic arachnids
In general characteristics of insects there are three pairs of legs attached to the thorax and the two pairs of wings are attached to?
Second and third thoracic segments
In insects, the hardened portion of the body wall is the deposition of a substance called?
Chitin
Describe sclerites
These are the segment of the body of an insect that is composed of a dorsal, lateral, and ventral areas
In an insect each segment of the body is composed of dorsal, lateral, and ventral areas and this is separated from each other by?
Sutures
Insect mouth parts are classified into?
A. Mandibulate for chewing
B. Haustellate for sucking
C. Piercing
D. Non-piercing
It causes pink eye
Mycobacterium bovis
The skin of the last larval stage is cast off and the pupa remains bare or naked or uncovered
Exarate or free pupae
In this type of larva there are thoracic and abdominal segments with legs
Polypod larva
This is a larva that no abdominal appendages are present, only three pairs of thoracic legs such as beetle grubs
Oligapod larva
Which type of larva has no thoracic and abdominal legs and often called maggots
Apodous larva
Dipterous insect larvae belongs to what type of larva
Apodous larva
In which types of pupa is the skin of the last larval stage may be cast off but head, legs, and wings are bound to the body by molting fluid
Obtectate pupa
This is a type of female insects in which the female reproduces without the need to be fertilized by males such as silkworm
Parthenogenetic
Describe oviparous or oviviparous
It is a female insect that lays eggs with fully developed larva
What is the difference between viviparous and pupiparous?
Viviparous deposits fully developed larva but pupiparous deposits pupa or larva that transform to pupa in few hours
The foregot or stomadeum of the digestive system is composed of what organs
Mouth, pharynx, esophagus, crop, and gizzard or preventriculus
The hindgut of the digestive system is composed of what organs

Rectum
Anus
Malpighian tubules
These are the openings on the tracheal tubes that are on the each side of thoracic and abdominal segments
Spiracles or stigmata
Most female insects have a storage sack for sperms or called as?
Spermatheca
Give the types of larva
Apodous
Oligapod
Polypod
