The above summary, if the samples be representative, indicates 

 a considerably higher percentage of infestation in Genesee, Monroe, 

 Niagara and Wayne counties in the western part of the State and 

 Schoharie county in the eastern part, with Cattaraugus, Cayuga and 

 Erie county grain fields nearly as badly infested. The Schoharie 

 county record is based upon samples taken from but one field and 

 is therefore not necessarily representative, and the same is true of 

 Cattaraugus and to a less extent of Erie county. This latter, judg- 

 ing from conditions in 1918 and the data secured earlier last season 

 by Mr Strickland, would indicate an infestation in the northern 

 portion at least approximating closely that obtaining in Niagara 

 county. 



The preceding data do not represent conditions fairly because 

 the collecting of the wheat samples was a little late to obtain the 

 maximum number of maggots and, furthermore, as a period of sev- 

 eral months elapsed between the gathering of the material and the 

 examination of the heads for wheat midge, there was an additional 

 opportunity for maggots to escape. The intimate relation between 

 reduction in the crop and the number of maggots is more clearly 

 brought out in a few samples collected in late June and early July 

 before there was any considerable desertion of the wheat heads by 

 the maggots.
