THE CONTROL OF THE CODLING MOTH IN THE PECOS VALLEY IN NEW MEXICO. By A. L. QuAiNTANCE, in Charge of Deciduous Fruit Insect Investigations. INTRODUCTION. For some years complaints have been received by the Bureau of Entomology from the fruit growers in the Pecos Valley, N. Mex., of the severe injury to apples and pears by the codling moth (Carpocapsa pomonella L.). The methods employed m the control of this insect m other apple-growuig regions have, m the Pecos Valley, been stated to be there much less efficient, so that a considerable portion of the crop of fruit has been wormy and unsalable. The codluig moth should yield as readily to treatment in the Pecos Valley as eisewliere, though, owmg to favorable clunatic conditions, it was surmised that it might develop an additional generation. It was not beheved, however, that the behavior of the insect in that region was essentially different from its behavior in other sections, and the lack of satisfactory results from spraymg operations, it was thought, probably resulted from failure to accomphsh this work m a thorough and timely manner. Begmning in the sprmg of 1912 an mvestigation of the codling moth was undertaken by the Bureau of Entomology, with head- quarters at RosweU, N. Mex., and Mr. A. G. Hammar, who had had much experience with this insect at other field stations of the bureau, was assigned to the work. During that year he was assisted by IMr. Earl R. Van Leeuwen, and durmg 1913 by ^Ir. L. L. Scott and ^li. E. W. Geyer. Owing to the unfortunate death of ^Ii\ Hammar there devolves upon the writer the necessity of preparing for pubhcation, for the benefit of the Pecos Valley fruit growers, the results of IVir. Hammar's experiments. The investigations carried out by Mr. Hammar comprise a thorough inquiry into the life history and habits of the
