The purpose of this investigation has been to determine the distribution and extent of injury of some of the more important jointworm flies attacking small grains. These obscure enemies exact a yearly toll by causing a subtle shrinkage in the weight and a decrease in quality of grain yields and, incidentally, a shrinkage in the profits derived from the farmer's labors, In general, jointworm flies may be controlled by simple, previously-known methods of improved farm practices, requiring no additional outlay in cash but a better timing and proper execution of good farm practices.
