Green ash is one of the few tree species rejected as food by larvae of the generalist gypsy moth,Lymantria dispar L. (Lepidoptera: Lymantriidae). Such rejection is based especially on chemicals present in green ash foliage. The gypsy moth larval feed

Hypocotyls of PI 227687 and ‘Davis’ soybean, Glycine max (L.) Merrill, were used in a dual-choice feeding preference assay with fifth-instar soybean loopers, Pseudoplusia includens (Walker). (Lepidoptera: Noctuidae). Constitutive resistance in hy
