IS badly infested with the Gipsy Moth. Further colonization will be necessary 

 next summer. 



In addition to the parasites already mentioned which are the most prominent 

 that have been liberated are two parasites of Gipsy Moth eggs, namely, Anastatus 

 hifasciatus and Schedius kuvance which are doing excellent service. These tiny 

 insects spread slowly, hence it is necessary to liberate large numbers of colonies. 

 By the end of another season it is hoped that the area most heavily infested with 

 the Gipsy Moth will have been thoroughly colonized with these species. 



Since the work was begun at the Gipsy Moth Laboratory, an effort has been 

 made to learn as much as possible concerning the life history and habits of the 

 parasites introduced, as well as their behavior, both under laboratory and field 

 conditions. 



The principal effort that has been made, however, has been to secure all in- 

 formation possible that had any bearing on the methods of successfully colon- 

 izing the species in the field, and obtaining information which would enable the 

 work to be intelligently handled. 



Since it is not deemed necessary to recolonize the area where the parasites are 

 known to exist, a limited amount of time has been given to studying more closely 

 the habits and relations of the introduced species and of our native parasites as 

 well as native hosts. This work is showing some interesting results, but much of 

 the data is far from complete. 



In closing, I would like to express my pleasure at the cordial and satisfactory 

 relations that have already existed between the work which is being carried on at 

 Melrose and that \vhich is under the direction of Dr. Hewitt. A hearty spirit of 

 co-operation has existed among the men conneicted with the work and most satis- 

 factory results are being secured. 



Mr. Gibson : I would like to ask Mr. Burgess what the total number of food 

 plants now is upon which the Gipsy Moth feeds? 



Mr. Burgess: I cannot s^y just at the present moment but there are a large 

 number. 



]\IR. Treherne: We took some specimens of Gipsy Moth from Japan a few 

 years ago. Has a study been made of the parasites of this insect there? 



Mr. Burgess : There has been some work done in Japan on the Gipsy Moth. 

 Professor Kincaid from the University of Washington made a trip to Japan for 

 the Department some years ago and studied the Gipsy Moth to a limited extent 

 while making collections of parasites for shipment to this country. As far as I 

 know, that is the only study by an American that has been made of the Gipsy Moth 

 of Japan. I should consider that it would be dangerous to import the eggs of the 

 Gipsy Moth into any uninfested .section of this country-. 



Mr. Winx: If there are no more discussions on the Brown-tail and Gipsy 

 Cloths I will now ask ^fr. Gibson for his paper on " Locust Control Work with 

 Poisoned Baits in Eastern Canada in 1915.''
