5. Many insect predators (e. g. ladybird beetles) are very effective at limiting the numbers of their invertebrate prey (e. g. aphids). As the prey become more
abundant, the predators both take more prey and become more numerous.
This is the basis of biological control programs in which an invertebrate
predator is introduced to control the numbers of an insect pest. Once the
numbers of the pest are reduced, both populations stabilize at a low level:
Why do you think a successful biological control program relies on the
predator having just one prey source (the pest)?
