Abstract
During outbreaks, some insect pests (may beetle, nun moth, oak tortrix and winter moth) change to plants not usually attacked because of a scarcity or absence of their normal host but the causes of several recently observed changes of food plant, in spite of an apparent sufficiency of normal food, are not known. Three such cases are described: Coleophora laricella Hbn. on Douglas fir, Liothrips setinodis Rtr. on deciduous trees and Acronycta rumicis L. on seedlings of Douglas fir and larch.
