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.

Book Description
Excerpt from Kill of Pink Bollworms in the Cotton Gin and the Oil Mill Most of the larvae of late-season generations of the pink bollworm remain in bolls and there enter the diapause, or resting stage, in which, under natural conditions, they live through the winter. Lar vae that survive the winter in the field do so mostly in waste cotton remaining after harvest. It has long been recognized that cotton infested with the pink bollworm should be harvested thoroughly and transported in a way that avoids deposition of waste along road sides, in order that as many as possible of the worms may be carried to the gin rather than left to infest the next year's crop.
