GIPSY MOTH WORK IN NEW ENGLAND.

ticut. Accordingly early in the spring arrangements were made to 

 place tanglefoot bands on trees in all the colonies about three towns 

 wide along the border and from the time this work began the greater 

 part of the scouting force was transferred to the work of applying 

 and patrolling these bands. 



In the colony in Westchester County, N. Y., 6,000 tanglefoot and 

 4,000 burlap bands were applied by the inspectors of the State depart- 

 ment of agriculture. The State purchased a high-power spraying 

 machine and very thoroughly sprayed the infested area and surround- 

 ings. The colony in Ohio was similarly treated by the State officials, 

 and in both cases excellent results have been secured. This office has 

 kept in constant touch with the work in these States and has also had 

 a representative directing the work in the Berkshire Hills infestations 

 in Great Barrington, Stockbridge, and Lenox. 



Inasmuch as many of the new infestations were found on apple 

 trees during the winter, a record has been kept of all such trees 

 inspected and of the number of miles of roads scouted by the men. 

 This information is given in the following table:

i In a number of these colonies pupa cases only were found. 



The following conditions found in 1913 and in 1914 are of interest. 

 In New Hampshire no egg clusters were found in 198 of the colonies 

 that had been treated during the previous years, and in 641 of the 

 1,656 colonies found in the winter of 1913 no larvae were found in the 

 spring of 1914. In Massachusetts no egg clusters were found in 68 

 of the colonies that were treated during the winter of 1912-13, and in 

 124 of the 794 colonies located in the fall of 1913 no larvae were found 

 in the spring of 1914. In Rhode Island 276 of the 309 colonies found 

 and treated in the fall of 1913 failed to produce larvae in the spring of 

 1914. In Connecticut 136 of the 157 colonies treated in 1913 failed 

 to produce larvae the following spring. 



During the summer of 1914 woodland scouting was carried on in 

 Thompson, Conn., and Rutland, Mass. The former town is heavily 

 wooded and is reported to contain about 30,000 acres of forest, a con- 

 siderable part of which is oak growth. As a result of the examina- 

 tion of the woodland in this town 73 gipsy-moth colonies were discov- 

 ered. All of them were small infestations, indicating that the species 

 is established and is well scattered through the woodland.
