48 INJURIOUS INSECTS OF 1903. 



Renville, Renville County, Minn., 

 Sept. 15, 1903.

 Dear Sir: The grain is now all cut, and it is estimated that the dam- 

 age done to the crops by the Hessian Fly amounts to about one-third of 

 the crop. 



The "Strawberry Slug" is doing considerable damage to the straw- 

 berry plants. The Ciit Worm has been very bad on garden products. 

 The White Grub has also bothered. And then there is a long brown 

 worm; I don't know what it is called. It is about ij^ inches long, very 

 slender, and has two horns, and its body has hairs scattered over it. This 

 worm was quite abundant on the strawberries, and now it comes into the 

 houses. The neighbors all around are bothered with it. It is a perfect 

 nuisance. 



Last spring the Leaf Aphis did some damage to the apple trees, but 

 not enough to kill the entire crop. 



On some places the- Potato Beetle killed the potato stalks entirely, 

 but cannot tell just what the loss would be. 

 Very truly, 



RUTH H. HOLMBERG. 



Buffalo, Wright County, Minn.,

 Prof. F. L. Washburn, 



Dear Sir: By far the greatest damage this year has been done by 

 Chinch Bugs. On sandy land, where wheat should have yielded 15 bu. 

 or more per acre, the yield was cut down often one-half to two-thirds. I 

 know of one case where less than 5' bu. per acre was harvested. Prob- 

 ably there were other places equally as poor. On rich ground there was 

 no trouble. 



Plant Lice come next in extent of injury. They worked mostly on 

 apple and plum trees, not killing them, but giving some of them quite a 

 setback. Also worked on box elder and on snowballs. 



Currant Worms were general on currant and gooseberry bushes. 

 The first brood did the damage; second did not amount to much. 



Potato Bugs were very numerous during the first week in July. 

 Where Paris Green was used, little damage was done. 



Tent Caterpillars were noticed on plum and hickory trees about 

 middle of August. These are still at work. In some cases hickory trees 

 have been nearly stripped of their leaves. 



Respectfully yours, 



G. R. MILLS.
