Book excerpt: Excerpt from Preliminary Report Upon the Infestation and General Status of the European Corn Borer in Western New York The earlier Observations were made primarily to determine the extent and seriousness of the infestation in the western New York area, while later observations were intended to supply information to interested persons concerning the progress of the infestation. The early Observations showed no severe damage in western New York, but the fact that other areas had experienced severe damage indi cated that the infestation in western New York might become seri ous enough to interfere with the production Of corn, which is an important crop in this area. When first discovered in 1919, the insect was infesting an area of approximately 25 square miles in the vicinity of Silver Creek, Chautauqua County. On July 1, 1920, there were 469 square miles of infested territory in the area border ing Lake Erie. Not only had the insect spread to new territory, but the original infestation in Chautauqua County had become more severe. In 1926 practically the whole of New York State and one half of Pennsylvania had become infested. Observations were made in ears, stubble, and entire plants. Most of the Observations of ears were made at canning factories, although it was Often possible to examine small numbers of ears in the field. Whenever possible, the sample used in estimating the degree of plant infestation in a field amounted to 100 plants per acre, but the minimum in any one field was 100 plants and the maximum, 500 plants, equal numbers of consecutive plants being taken in the center of each quarter and in the center of the field. The same method of selection was used in making stubble Observations. The 1920 infestation was comparatively light, and no commercial damage was noted. The most severe infestation was found in a small field of early planted sweet corn, where 45 per cent of the plants were found to be infested. The maximum stubble infesta tion in 1921 was per cent. After 1921 the degree of infestation increased steadily until 1926, when approximately 67 per cent of the plants in the area under Observation were infested. At this time the average infested plant contained larvae. During the period prior to 1927 the degree of infestation increased from 65 larvae per 100 plants in 1921 to 242 larvae per 100 plants in 1926. No general commercial damage occurred prior to 1926, although reports from individuals in 1924 and 1925 indicated isolated cases of commercial damage. In 1926 commercial damage was general, and it was neces sary for canning factories to employ special field inspectors and additional helpers at the sorting tables. It was also necessary in 1926 to use special machinery in treating infested ears. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
