Question

Why is biological control sometimes considered the best option to control an invasive species, even if there are some risks?

Answer 1

Answer:

b. It is a much cheaper option than other control strategies

c. The negative effects of the invasive species on native species are severe

Explanation:

Biological control is the use of an organism (predator, parasite or pathogen) that attacks another that is causing economic damage to crops. This is a strategy widely used in agroecological systems, as well as in conventional agriculture that uses Integrated Pest Management (IPM).

In addition to being cheaper, this technique reduces the risk of residues on crops such as fruits and vegetables. The technique is to use a predator or parasitoid of a specific invasive species when the negative effects of invasive species on native species are severe.

The cost of this technique is very low, as there is no need to use chemicals.
