It was necessary, therefore, to grow small experimental plats of the more important field crops at Med ford, Sangns, Cambridge, Belmont, and Woburn, Mass., in order to ascertain the reaction of the insect to them. It seemed desirable to include such other important field crops as are normally grown in the South and West, with the object of obtaining advance information regarding the adaptability of the insect to these Fig Oats showing European corn-borer larvae infest in? stem The experimental plats were duplicated at Scotia and Silver Creek, N. Y., but most of the information included herewith was obtained from the Massachusetts plats, where the insect is more numerous and habitually attacks a greater variety of plants under field conditions. The results obtained should be considered as merely indicative, because it does not seem possible definitely to forecast the reaction of P. nubilalls to some of these crops, under American conditions, if the insect should become well established where they are extensively grown. A summary of the observations relating to the character t" injury to field crops is included in Table Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States.
