The Look and Behaviour of pests

Most of the pests that occur in food are insects. This is probably obvious. Today about 1 million species of insects are known and it is estimated that there are still many millions of unknown species of insects. Insects are by far that group of animals with the most members.

Some knowledge on the insects’ appearance and build is useful to be able to tell them apart and to know which insects are occasionally found in food. It is also quite useful to know something about insect behaviour. When trying to prevent or control pests, it is important to be able to make qualified guesses on the insect behaviour under certain circumstances. In most cases prevention and control is all about creating conditions for pests in which they do not thrive.
