causing the insect to look elsewhere for a suitable food source. Many antifeedants are bitter.

Insects have gustatory receptors on various parts of the body, not only on the mouth parts. Some can taste with their feet (tarsi). An insect moving away after detecting an antifeedant with its tarsi and without biting into the plant is sometimes referred to as an irritant mechanism or a suppressant.

Insects can become habituated to antifeedants and can even evolve over generations to use 'repellents'
