What is the term for the negative effect that a host plant has on the growth of an insect pest that feeds on it?

Correct option is B

· Antibiosis refers to the negative effect of a host plant on insect-pests due to the production of toxic chemicals or low nutritional quality.
· This mechanism reduces insect survival, growth, and reproduction, making the host plant unsuitable.
· In contrast, antixenosis affects insect preference rather than survival.
