plants other than the trap patch. This corn grown for fod- 

 der or silage is carefully utilized during winter which reduces 

 the pest without any further fuss and fumble to the minimum 

 for spring infestation. 



What is wanted now in the interest of the public weal 

 is that the Secretary of Agriculture give the Entomologist a 

 da> off from other pressing duties of his office, real or fancied, 

 so that he may have time to define what is what in this method 

 of controlling what, is "probably the most injurious plant pest 

 yet introduced," as described on pages 1 to 11 of my Circular 

 No. 156. 



Sucidentally, the Entomologist has been for 3 years 

 wanting to show why such a trap patch of late cotton or corn 

 would not concentrate the bollworm or corn ear wcrm into 

 hibernating quarters, and by plowing the ground before 

 emergence begins in the spring, keep the bulk of the moths 

 from emerging in any given locality. 



If the borer finds its way to sections where it can produce 

 3 broods, the dates given have to be correspondingly advanced, 

 and an extra sowing of corn made to tassel by about August 

 20. 



In the South, this insect can produce 4 to 5 generations. 

 The dates as given for Massachusetts have then- to be* still 

 further advanced and the use of trap crops, corn or other suit- 

 able crops has to be carried on longer in the fall. 



There is every reason to believe that should this pest find 

 its way to the cotton belt, it would prove to be a far more 

 formidable pest to cotton under the crude method of control
