6 INJURIOUS INSECTS OF KANSAS. 



In the succeeding pages the life-history and characters of each 

 pest considered are briefly given. The rationale of the remedies 

 proposed is thus made plain, and suggestions may come to some 

 looking to the discovery of new remedies, or to the application of 

 others not mentioned. The "Diagnoses" will serve to determine 

 the specific pest which may be at work in the grain, vegetable or 

 fruit attacked. I have included in the diagnoses the character- 

 istics of the injury done, as well as the prominent characters of 

 the insect pest in that life-stage in which the injury is done. The 

 diagnoses may nearly serve as a sort of key for the determination 

 of the 50 and more insect pests discussed. As to remedies, in 

 order to save a tiresome repetition, and more especially to econo- 

 mize space, I have, in the following chapter, considered each of 

 the more important insecticides in some detail, defining their char- 

 acter and giving approved methods of preparation and applica- 

 tion. Under the head " Remedies " for each insect pest, the names 

 of the suitable insecticides to be used are given, referring to the 

 special chaj^ter on remedies for the necessary information as to 

 mode of use. The " Kansas Notes," finally, will be of interest to 

 inquiring minds, and may be of some use to working entomolo- 

 gists.
