Antibiosis is a biological interaction between two or more organisms that is detrimental to at least one of them or an antagonistic association between an organism and the metabolic substances produced by another.

The general relationship between an antibiotic and an infectious organism is one of antibiosis. This word refers to an association of two organisms in which one is harmed or killed by the other. The relationship between human beings and disease-causing pathogens is one of antibiosis. If a person is affected by germs, he is the injured organism.

Antibiosis is commonly found and studied between host plants and the insects which feed upon them.

"Antibiosis resistance affects the biology of the insect so pest abundance and subsequent damage is reduced compared to that which would have occurred if the insect was on a susceptible crop variety. Antibiosis resistance often results in increased mortality or reduced longevity and reproduction of the insect."1
