28 INJURIOUS INSECTS OF KANSAS. 



weeks. Thex'e are probably two broods in Kansas, the larvae of 

 the first paying special attention to early sweet-corn. 



Remedies. — It is the very early (first brood) and very late (sec- 

 ond brood) corn that suffers most, so that intermediately-ripening- 

 corn is apt to be comparatively free from attack. Hand-picking 

 is the most available and effective remedy so far devised. "The 

 silk of infested ears shows the presence of the larvae by being 

 prematurely dry or partially eaten, and the larvae may be readily 

 found and crushed. In garden patches of sweet-corn, at least, 

 this method is worth using." Fall plowing of infested fields will 

 break up and expose many pupae. 



Kansas Notes. — Dr. Riley, in his third annual report as State 

 Entomologist of Missouri, says : 



In 1860, the year of the great drouth in Kansas, the corn crop in 

 that State was almost entirely ruined by the Corn-worm. According to 

 the Prairie Farmer of January 31, 1861, one county there, which raised 

 436,000 bushels of corn in 1859, only produced 5,000 bushels of poor, 

 wormy stuff in 1860; and this, we are told, was a fair sample of most 

 of the counties in Kansas. ... It appears, also, that many horses 

 in Kansas subsequently died from disease, occasioned by having this- 

 half-eaten, wormy corn fed out to them.
