Excerpt from Damage to Sugar Cane in Louisiana by the Sugar-Cane Borer One of the special lines of work planned by Mr. D. L. Van Dine, when the laboratory for the investigation of sugar-cane insects was established by this Bureau in 1910, was the determination of the various classes of injury caused by the cane borer. Observations and experiments were conducted by the writer in 1910. It was discovered that the borer is responsible for much more injury than is apparent at first sight. Its harmful work begins with the destruction of eyes of seed cane, reducing the stand during the following year; con tinnes through the growing season of the cane by stunting its growth, and causing damage from windstorms, owing to the weakening of the stalk due to the burrows and girdles; and ends by causing a much lower percentage of juice, which is again of a much poorer quality in infested canes than in uninfested canes. The last is an important form of injury, which appears to have been overlooked by investigators and planters. Moreover, the holes made by the cane borers are the chief means of entrance to the stalk afforded the various fungous diseases of the sugar cane. The tonnage yield per acre is reduced by borers, and the average weight of canes otherwise similar in appearance is found to be reduced by borer infestation. These points will be explained in detail under the following head ings: Injury to seed cane; injury to growing cane; injury to mature cane and juice.
