Biological Controls

What is the general definition of biological control?

Biological control is a method of controlling pests such as insects, weeds and diseases using other organisms and natural mechanisms.

Modifying genetic information to alter genes.

Controlling things biologically.

What are the 3 types of biological control?

Augmentation, exportation, conservation

Augmentation, importation, preservation

Augmentation, importation, conservation

What does importation of biological controls mean?

When a natural predator is introduced in the hope of achieving control.

When natural predators are bred and released to improve control.

When measures are taken to increase natural predators in the hope to achieve control.

What does augmentation of biological controls mean?

When a natural predator is introduced in the hope of achieving control.

When natural predators are bred and released to improve control.

When measures are taken to increase natural predators in the hope to achieve control.

What does conservation of biological controls?

When a natural predator is introduced in the hope of achieving control.

When natural predators are bred and released to improve control.

When measures are taken to increase natural predators in the hope to achieve control.

Give an example of a case study where biological controls were implemented.

What is a mealybug and what is it a natural predator towards?

A grain that was used as a source of food hundreds of years ago.

The mealybug is a rare insect that spread rapidly over the entire cassava growing area of the continent.

It is an ant-like bug that is a predator towards snails.

How was a biological control implemented to control the mealybug?

Genes of the cassava were modified.

The release of the wasp caused mealybugs to flourish, increasing abundance.

The release of a tiny wasp whose larvae would grow inside the mealybug and eventually kill it.

What type of biological control was implemented in the 'Casava Mealybug' case study?

Augmentation

Importation

Conservation
