The codling moth continues to be the most s serious pest of the Utah horticulturist and was therefore made the main subject of investigation by the Entomological Department for the season of 1904.
In spite of the immense amount of work that ha been done on this subject by various entomologists in this and other countries, several vital points still remain unknown and many more that have been worked out for other localities must be verified and adapted to our conditions.
