The addition of both the “juice” and ether soluble “extract” from resistant to susceptible corn reduced larval survival to approximately half that found on plants treated with distilled water. These results indicate that at least a portion of the resistance of inbred CI31A, and of the single cross CI31A ✕ B49, is caused by a feeding deterrent of toxic substance present in these plants. The addition of juice or extract from susceptible plants to resistant plants had no effect on larval survival.
