To establish the successive rearing method of the lesser mulberry pyralid, Glyphodes pyloalis WALKER, experiments were made with a commercial silkworm diet.Addition of the juice of frozen mulberry leaves or young mulberry leaf powder into the artificial diet improved the diets, so that the larvae were arrested and reared in an open container. The pupal and adult yields on the improved diets were larger than those on the basic silkworm diet.
