246 Twenty-Second Annual Report of the 



ermine moth 



In 1913, during the summer months a newly imported insect, 

 the Cherry ermine moth, was found on some apple and cherry 

 seedlings imported from France for planting in the spring of that 

 year. Efforts were made to exterminate the pest, but we have 

 reason to fear that some have escaped. 



In 1.914, a thorough canvass was made of all seedlings planted 

 and also of the product of 1913 plantings and many nests of the 

 ermine moth were destroyed. 



During 1915 special attention has been given to the subject 

 again with the result that we have captured and destroyed 3,600 

 nests of this pest in various parts of the State. Careful attention 

 should be given to this pest another year with the hope of eradicat- 

 ing it.
