Arthropods Flashcards
Causes scabies
Sarcoptes scabiei
The leading edge of insect wings
Costa
This type, as exemplified by houseflies is adapted for sucking up liquid or readily soluble foods
Sponging mouthparts
external openings of the respiratory system
spiracles
also known as crab lice which infest on coarse hair in the pubic area
Pubic Lice (Phthirus pubis)
Head lice eggs
Nits
Arthropods that are aquatic in nature
Class Crustacea
Arthropods that are both aquatic and terrestrial in nature
Class Arachnida
excretory organ of insects
Malphigian tubules
These are membranous extensions of the body wall and consists of an upper and lower layer.
Wings
This is released by the head lice eggs
Nymph
This is the most important vector of malaria in the Philippines
Anopheles flavirostris
colorless insect blood
hemolymph
Adult lice can live up to how many days on a person’s head?
30 days
There are two types of eyes occur in insects namely: single and compound. Which of this are usually very large, round, or kidney shaped?
Compound
consists of insects described as “cone-nosed” because they have narrow, pointed, cone-shaped heads
Order Hemiptera
A kind of vector that undergoes multiplication, propagation, and development inside the arthropod’s body
Biological vector
In this type of metamorphosis, the young resembles that adults except for the smaller size and sexual immaturity
Gradual/Incomplete
number of legs of Arachnidas
4 pairs
number of antennae of Crustaceans
2 pairs
Head louse:
Body Louse:
Head louse: P.h. capitis
Body Louse: P.h humanus
Part of the insect which bears the eyes, antennae, and the mouthparts
Head
refers to the change in structure of an arthropod that occurs during the period of development
Metamorphosis
posterior part of the esophagus that serves as an area for temporary storage of food
crop
Mandibles and maxillae are of chewing type and are used for grasping prey or molding wax
Chewing-lapping mouthparts
Human body louse
Pediculus humanus
One of the special mechanisms of arthropods which is primarily a nitrogenous polysaccharide that makes the integument impervious to water
Chitinized exoskeleton
Human flea
Pulex irritans
This is the second main body region of insects which is connected to the head by the neck or cervix
Thorax
Number of molts until nymphs mature
Nymphs mature after three molts
a small valve-like openings where hemolymph flows
ostia
Membranous-winged arthropods
Order Hymenoptera
Treatment for head lice
Benzene hexachloride
Class of centipedes
Class Chilopodia
The entire structure of this mouthpart type is called the proboscis
Piercing-sucking mouthparts
Diagnosis of this parasite is made by the characteristic rash and by smearing black ink on the skin
Scabies mites
The vectors of Bancroftian filiariasis in the Ph
Aedes poecilus
Three major regions of the body an insect
head, thorax, abdomen
The outer surface of the compound eye is composed of these small six-sided lenses called
facets
(Active flying insects have many facets while walking types have fewer)
What class do crabs, crayfish, and copepods belonged?
Class Crustacea
Primarily known as the “tiger mosquito” which is the vector of dengue in Ph
Aedes aegypti
entire body cavity
hemocoel
Known as jigger, chigger, or sand flea
Tunga penetrans
A type of insect mouthparts which use their mouthparts to grind solid food. Examples are cockroaches and silverfish
Chewing mountains
These mosquitoes are exophagic and exophilic wherein the peak of biting is observed at 1:00 am to 2:00 am
Mansonia
fingerlike processes in the insect abdomen which are more conspicuous in females
cerci
In this type of metamorphosis, there is a great difference between the immature stages and adults
