It states: "The experience of last season with the European corn borer leads the United States Department of Agricul- ture to make the statement that appar- ently there is little justification for un- due alarm over the possibility of this insect becoming a menace to the corn crop throughout the entire country. "It was perfectly natural at the out- set, when it was discovered that this insect was working considerable harm to small patches of sweet corn and the dwarf flint corn grown about Boston, that grave fears for the future of the corn crop of this country should be aroused. The facts as now known, how- ever, give basis for a material modifi- cation of the earlier judgments as to the possible future importance of this insect. Injury Is Negligible. "Up to the present time the corn borer has inflicted considerable damage to corn only in the Boston district, where the corn grown is of the sweet and dwarf varieties and where the corn borer, owing to the climatic influence of the Gulf stream, is 2-brooded. How- ever, in most of the fields in the area now invaded in coastal Massachusetts and New Hampshire, the injury has been negligible. When the corn-borer larvte are limited to the stalks the ears, as a rule, are normal. Even when the larvae enter the ears the injury is cer- tainly not greater than that caused by the ordinary corn ear worm, which is reckoned at about seven per cent by weight of the kernels of each ear at- tacked. The presence of corn-borer larvae in ears of sweet com has not prevented the sale of the corn and, in most instances, it has been sold at the ordinary market ; Because it is single-brooded in that region, there is little danger of the in- sect being a menace to the corn fields of the central states, the government experts say.
