Question

What is the biological principle behind the biological control method of managing pest insects?

Answer 1

The basis of various biological control methods is on the concept of predation. Predation is a biological interaction between the predator and the prey, whereby the predator feeds on the prey. Hence, the predators regulate the population of preys in a habitat, thereby helping in the management of pest insects.

Answer 2

The biological principle behind the biological control method of managing pest insects is predation.  

Explanation:

• The biological control method of insect pests exploits the prey-predator relationship whereby predators of certain insects are used to control the population of the insect pests.  

• The bio control method for pests is beneficial as it reduces the use of insecticides, pesticides and is non-hazardous to the environment.  

• However, this method requires human intervention to introduce predators and to remove them once pests have been controlled.  

• This method is largely used for controlling mites, weed ad mosquito larvae.
