FIELD WOBK AGAINST GIPSY AND BKOWN-TAIL MOTHS. 



Conn., December 14. It was visited by Mr. Rogers, December 20, 

 and arrangements were made with Dr. W. E. Britton, state entomolo- 

 gist of Connecticut, to cooperate in every possible way to stamp out 

 the pest. 



The above is a brief outline of the cooperative work which has been 

 carried on by the Bureau of Entomology in suppressing the gipsy 

 moth. 



Winter webs of the brown-tail moth have been destroyed whenever 

 they have been found in the belts which are being cleared along the 

 roadways. This insect has spread so rapidly that it has been impos- 

 sible to carry on an active campaign against it, and in Maine and New

Hampshire only a moderate amount of good would have been accom- 

 plished if an attempt had been made to destroy the brown-tail webs 

 along the roadways and in the orchards, as the woodlands, especially 

 in the southern part of these States, are very badly infested. In 

 many towns property owners have destroyed the webs found on their 

 orchard and shade trees. 



The work of suppressing the gipsy moth is carried on in a diflFerent 

 way in each of the New England States. In Massachusetts a large 

 annual appropriation is made by the State, and property owners as well 

 as towns and cities are required to assist in the control of the insect.
