Question

Which one of the following is NOT an action of biocontrol on a pest?

Options

• Increases the rate of reproduction

• Causes disease

• Competes

• Kills

Answer 1

Increases the rate of reproduction

Explanation:

Biological control reduces pest populations by actions such as killing them, causing disease with pathogens, or outcompeting them for resources. It does not act to increase a pest's reproductive rate; some biocontrol methods actually disrupt or suppress reproduction, for example, mating disruption or the sterile insect technique.
