The purpose of this study has been to determine the identity and the life history of certain larvae attacking dewberry fruits and foliage in a few sections of Utah. The dewberry fruit worm as it was called until it was definitely identified the oblique-banded leaf-roller, was first observed by farmers at Granite and Butlerville in 1932. Since 1934 it has been found affecting dewberries in other parts of northern Utah.
This investigation was begun in the spring of 1935 and continued until the fall of 1936, being made possible through the Utah Agricultural Experiment Station, Department of Entomology, and with the cooperation of various farmers in the vicinity of Granite, Utah. Field studies were made at Granite, Butlerville and southeast Pleasant Grove during the course of the investigation. Overwintering studies were carried on at Logan during the winter of 1935-36.
Since this insect is one of the most important pests of dewberries in Utah a careful study of its life history and habits was considered necessary before control methods were undertaken.
