Book Description
Excerpt from The Boll Worm of Cotton: A Report of Progress in a Supplementary Investigation of This Insect The present bulletin consists of a report made by Mr. F. W. Mally upon the progress of the Special investigation of the Cotton Boll-worm which has been carried on under the Division since the appropriation became available, July 1, 1890. Mr. Mally has had charge of the minor details of the investigation, and has been constantly in the field since last July. He also summarizes the results Obtained by Messrs. Mc Neill and Booth. The Boll Worm was treated at some length in the Fourth Report of the U. S. Entomological Commission, and the chief Object of the present investigation was to conduct further experiments with remedies, as well as to verify the value of those already employed. A thorough series of experiments has been planned with the diseases of Heliothis and allied insects, in the hope of being able to practically utilize them. Incidentally I have desired to ascertain new facts, if possible, and to verify or disprove what has been previously written in connection with the life history and habits of the Species.
