Abstract:
Plant-insect interaction is an important field for studying plant immunity. The beet armyworm, Spodoptera exigua, is one of the best-known agricultural pest insects and is usually used to study plant interactions with chewing insects. Here, we describe a protocol for insect feeding assays with Spodoptera exigua lavae using model host plant Arabidopsis thaliana, which is simple and easy to conduct, and can be used to evaluate the effect of host genes on insect growth and thus to study plant resistance to chewing insects.
