300 CONNECTICUT EXPERIMENT STATION REPORT, I907-I908. 



Carbon bisulphide will kill the insect in the larval and pupal 

 stages, but is probably too expensive to warrant its use ; besides 

 there is no injector with which to apply it, on the market at the 

 present time.

PROGRESS OF THE WORK OF CONTROLLING THE 

 GYPSY MOTH IN CONNECTICUT. 



The first account of the discovery of the gypsy moth in Con- 

 necticut in March, 1906, was published in Bulletin 153 of this 

 station. The report for 1905 was then being prepared, and in 

 it was included, on page 246, a more complete history of the 

 discovery. Work was started immediately and kept up until 

 September ist. The details were published in full in the report 

 for 1906, page 235. The present paper is a report of progress 

 during the calendar year of 1907. 



Beginning November i6th, 1906, Mr. George H. Hollister has 

 had immediate supervision of the work, and to his faithfulness 

 and ability much of its success is due. During the winter three 

 men worked with Mr. Hollister, scouting for egg-masses, prun- 

 ing trees and cutting brush. After the caterpillar season began, 

 the force was increased, twenty being the greatest number of 

 men employed at any one time during the banding season. 

 Excellent progress has been made in the suppression work, as a 

 large number of trees were banded, brush cut and trees pruned 

 over a large area, and the total number of caterpillars found 

 was less than one-third the number taken during 1906. 



On September ist the work was suspended on account of the 

 annual inspection of nurseries, and again resumed on November
