Question
What is the ecological principle behind the biological control method of managing with pest insects?
Solution
Biological pest control is mostly reliant on predator-prey relationships. Baculoviruses (mainly of the Nucleopolyhedrovirus genus) are effective at controlling a wide range of insects and arthropods. Beetles (such as the Coccinella or ladybird beetle) control aphids and other pests. Gambusia, a fish, is introduced into ponds to control mosquito larval proliferation. Biological control strategies used in agricultural pest control rely on the predator's capacity to regulate its prey.
