INJURIOUS INSECTS OF 1903. 45 



treat their cabbage the same as their potatoes, with Paris Green for the 

 Potato Beetle, they are easily kept down. 



As to fruit, the Codling Moth is more prevalent this year than ordi- 

 nary, and the Curculio has been more numerous than in recent years. I 

 put up a fight with them for about thirty days and saved my plums in 

 very good shape, but from present indications I fear rot at about matur- 

 ity. The Currant Worm has been very destructive. I do not grow them. 

 The above seems to cover the ground for this section at this time. 



If you have blanks for this work please mail me a few.

Dear Sir: I have the following to report regarding insects injurious 

 to crops in this section for the past month: 



Aphis observed upon the wheat heads July 15th. They did consider- 

 able damage, causing a great many shrunken kernels. 



The first effects of the Hessian Fly were noticeable about the 2nd of 

 July. Considerable damage was done in this section. It is hard to esti- 

 mate the loss, as some grain also dropped on account of weak straw, 

 caused by rust earlier in the season. 



The Cabbage Worm is doing some damage to the cabbage, although 

 not very numerous. There are also some Aphis upon apple trees and 

 wild plums. No serious injury has been done by these. 

 Potato Bugs quite numerous this year. 

 Yours truly, 



E. A. HOLT.

Dear Sir: I have to report that the Hessian Fly has caused some 

 damage to wheat this season in this vicinity, to the probable extent of 

 5 per cent. I have found a great number of "flax seeds" in the stem 

 just above the first joint. 



Chinch Bugs have never done any damage in this neighborhood, but 

 my father says he has found a single one some years ago. He is familiar 

 with the pest, having seen thousands of them in his old home in Wis- 

 consin. 



Potato Bugs seemed very numerous early in June, but by timely ap- 

 plication of Paris Green solution their ravages were checked, and hence
