The following method of rearing the red-banded leaf roller, a pest that has recently become increasingly destructive and difficult to control on apple in Ontario, was developed to obtain a supply of insects for insecticide tests during the winter. No reference to methods of rearing this insect in the winter were found in the literature. As the Field Station at Simcoe has no greenhouse or plant growth room, the entire procedure was conducted in an office room and basement except that some of the bean plants used were obtained from the greenhouse of the Entomology Laboratory, Vineland Station, Ont.
