Maize $(Zea  mays)$ varieties that possess high levels of aspartic acid, along with low nitrogen and sugar content, are known to be resistant to the maize stem borer $(Chilo  partellus)$. This is a classic example of biochemical resistance in plants where the chemical composition of the plant tissue acts as a deterrent to the pest.
