Module 8 >>> Insects and Diseases

Question 1

To what does high vector competence of an insect disease vector refer?

1 / 1 point

The disease-causing organism is able to efficiently reproduce within the infected insect

The insect is able to survive for a long period of time after becoming infected with the disease-causing organism

The insect vector exists at the same time and in the same place as the disease-causing organism

The vector’s biology or behaviours make it effective at acquiring, maintaining and transmitting the disease-causing organism

=====================================================

Question 2

Which of the following best characterises biological disease transmission?

1 / 1 point

Direct contact between the vector and the host

Development or reproduction of the pathogen within the vector

The transmission of pathogens between generations of the vector

Development or reproduction of the pathogen within the host

=====================================================

Question 3

Which of the following best describes fire blight disease?

1 / 1 point

A disease of apple and pear that is only vectored by wind

A disease of apple and pear that can be vectored by insects, wind or water

A disease of potato that can be vectored by insects, wind or water

A disease of apple and pear that is only vectored by insects

A disease of potato that can be vectored by aphids

=====================================================

Question 4

Which of the following is an example of horizontal disease transmission?

1 / 1 point

A child contracts Zika virus when a pregnant mother is bitten by a mosquito

A pathogen is retained by a vector between moults

A species of tick is transported from Asia to North America

A tick transmits Lyme disease from a mouse to a human

A pathogen moves from a vector’s hemocoel to its reproductive organs

=====================================================

Question 5

Under what conditions are arthropod-borne diseases most severe?

1 / 1 point

Small populations of insect vectors are present within large populations of hosts

Small populations of insect vectors are present within small populations of hosts

Large populations of insect vectors are present within small populations of hosts

Large populations of insect vectors are present within large populations of hosts

=====================================================

Question 6

Which of the following statements are true? (select 2 that apply)

1 / 1 point

Vector control is the primary method of prevention for malaria

Malaria is more likely to cause significant harm with repeated infections

The Anopheles mosquitoes which transmit malaria can be targeted with bed nets and wall-spraying due to their night-feeding behaviour

Taking plant-derived antimalarial drugs to prevent malaria reduces the development of drug resistance in the Plasmodium parasites

=====================================================

Question 7

True or False: Insects and other arthropods only act as disease agents by vectoring diseases.

1 / 1 point

True

False

=====================================================

Question 8

True or False: Veterinary entomologists study insects and insect-related diseases that affect domestic animals as well as wildlife.

1 / 1 point

True

False

=====================================================

Question 9

What do filarial elephantiasis, dog heartworm, and malaria have in common?

1 / 1 point

All three disorders are transmitted by mosquitoes

All three disorders are transmitted by ticks

All three disorders are caused by filarial worms

All three disorders are primarily controlled using vector control methods

=====================================================

Question 10

Which of the following is NOT a method by which fire blight is spread?

1 / 1 point

Wind

Wood borers

Pollinators

Fire

Rain
