40 INJURIOUS INSECTS OF KANSAS. 



or a little later. There are at least two generations in a year. 

 The eggs are deposited on the under sides of the leaves of peach, 

 apple and other trees. 



Remedies. — As the last brood of the year must pass the winter 

 in the larval or pupal state in the ground, late fall plowing of 

 fields in which the pest has been present during the fall will prob- 

 ably kill many. Also, if ground which is to be put into wheat 

 be kept clean of vegetation before sowing, and the sowing be done 

 late, the early moths will not be attracted to the field to lay their 

 eggs. In Kansas in 1884, when the worm was numerous, many 

 farmers in Douglas county waited until September 20 to October 

 20 before sowing their wheat and rye, and then had no trouble 

 from the worm. 



If these worms are invading a field of fall grain, most of 

 them could be destroyed by running over them with a heavy roller 

 without injury to the grain. Fortunately, wheat which is cut off 

 by the worms is not necessarily destroyed. Several instances 

 where a field was quite cut down, and yet where a good stand was 

 got the following spring, are known. 



Kansas Notes. — In a letter to the Kansas Farmer dated August 

 29, 1870, a correspondent in Mineral Point, Anderson county, 

 calls attention to the presence of the pest, which is said to "take 

 a 25-acre field in two days." This writer says that they last ap- 

 peared in Kansas in 1866. 



In the Fourth Biennial Report of the Kansas Board of Agri- 

 culture (1883-84), Prof F. H. Snow contributes some notes on 

 this pest. It was present in considerable numbers in Douglas, 

 Leavenworth, Jefferson and Labette counties. In Douglas county 

 most of the damage was done during the first week in September. 

 Wheat and rye sowed after September 15 was uninjured.
