Question

Certain species of insects introduced accidentally in a forest are destroying all the Douglas fir trees in that forest. The wood of these trees is extensively used for construction. In order to control the damage caused by these insects, the forestry department decided to introduce the moth caterpillar in the forest. These caterpillars are natural predators of the insects. Which method did the forestry department implement to control the invasive species?
The forestry department implemented a(n) _______ control method.

Answer 1

Answer:  Biological control method

A biological control method is used to control the growth of unwanted and undesired species of plant and animals in a natural habitat.  This includes the induced growth of plants, animals and insects which help to irradicate the growth of undesired plants, animals and insects. Therefore, introduction of  invasive species of caterpillar moth will limit the population of insects causing harm to forest woods.

Answer 2

Invasive firestorm method.  All pests are now dead with the added benefit of fewer trees to infest.
