CHAPTER XIV 



GInrtt p^stH attn UtoaB*B 



O far as the writer has been able to find out 

 by careful examination of records and obser- 

 vation, two hundred and nineteen species of 

 insects have been recognized and recorded as 

 in seme way being injurious to some part of the 

 corn plant. For the sake of convenience, these have 

 been arranged according to their attacks upon the 

 various parts of the plant. For instance, eighteen 

 are known to infest the seed ; twenty-eight have been 

 discovered upon the root and underground parts 

 of the stalk ; seventy-seven have been recorded 

 as injuring the stalk above ground; one hundred 

 and nineteen attack the leaf- nineteen are known 

 to injure in some way the tassel and silk; forty- 

 three work upon the ear in the field; two have been 

 found upon stacked fodder; and twenty-five others in 

 corn in store or in manufactured products. Many of 

 the species recorded in this list are of minor impor- 

 tance, and only the primary ones, found more or less 

 injurious to the corn plant every year, are here con- 

 sidered. 



Perhaps the most serious injury to corn occurs 

 when insects attack the seed and the root. This usu- 

 ally happens early in the season, but fortunately for 

 farmers, much of this damage can be prevented by 

 precautionary and preventive measures at the proper 

 time. The following practical hints, as a brief intro- 

 duction to this chapter, will assist the average person 

 in recognizing the insects responsible for injury to 

 corn either in the field, in store or in the manufactured 

 products.
