THE EUEOPEAN CORN BORER AND ITS CONTROL. 67 



In Octoberj 1918, a Federal quarantine was established prohibiting the 

 interstate movement of corn fodder, cornstalks, green sweet corn, roasting 

 ears, corn on the cob and corn cobs from the towns known to be infested 

 by the European corn borer. 



In August, 1918, the State of Vermont issued a quarantine order pro- 

 hibiting the movement of all stalks or ears of the corn plant, either green 

 or dried, from the State of Massachusetts into the State of Vermont. 

 A similar quarantine has been established by Connecticut. 



During the spring of 1918 a campaign was inaugurated by the Massachu- 

 setts State Board of Agriculture for the destruction of all infested plants 

 within the infested area. This resulted in greatly curtaiHng the activities 

 of the insect during the following season. In October, 1918, this cam- 

 paign was resumed under the joint auspices of the Massachusetts State 

 Department of Agriculture and the United States Bureau of Entomology, 

 Division of Cereal and Forage Insect Investigations. 



0^\ang to the open winter of 1918-19 a continuation of the clean-up 

 work was possible to a greater extent than was expected. This, after 

 Dec. 1, 1918, was done mainly with funds pro\'ided by the United States 

 Bureau of Entomology. 



Since the preparation of this bulletin the European corn borer has been 

 found over an area of about 400 square miles near Schenectady, N. Y. 



To avoid any possible confusion as to responsibility for the material 

 contained in this bulletin, it should be stated that the sections on 

 Geographical Distribution, Quarantine Measures, Insects frequently 

 mistaken for the Corn Borer, the Introduction, and the Summary were 

 supplied by Mr. Caffrey. The observations under the heads of History 

 in the United States, Food Plants, Life History, Habits, and the others 

 were made by Mr. Vinal; the descriptions of the different stages were 

 the result of examination of specimens by Messrs. Vinal, Caffrey and 

 Femald.
