 The brown-tail moth [Euproctis chri/sorrhoea] in Nova Scotia occurs 

 mainly on fruit trees, the only forest or ornamental trees which are 

 attacked being those growing in or near orchards. In those countries 

 in which the orchards are small and scattered, control by the collection 

 of nests in winter has proved very elective. Where there arc large 

 continuous orchards or an abundance of wild seedling apples, control is 

 rendered nuich more difficult. The winter dropping of nests varies 

 from 10 to 25 per cent, of the total number. The larvae in such nests 

 appear to withstand the winter better than those in nests remaining 

 on the trees. As most of the nests drop in November and December, 

 their collection begins on 1st November. Control measures also 

 include educational work, spraying campaigns, and the liberation of 

 parasites, notably Apanteles lacteicolor. With regard to spraying, it 

 has been demonstrated that lime-sulphur and lead arsenate, applied 

 between 28th June and 15th July, remains adherent to the leaves 

 until after the emergence of larvae in August.

The brown-tail moth [Euproctis chrysorrhoea] is now endemic in the 

 transition zone in Nova Scotia. This indicates that this insect could 

 become a serious pest in other parts of Canada within the same zone, 

 such as British Columbia, Alberta, Ontario, Quebec, New Brunswick 

 and Prince Edward Island. The gipsy moth [Li/ntantria dispar] is also 

 a potential pest in the same provinces ; it hibernates successfully in 

 the northern parts of Maine and if introduced into Canada would find 

 an abundant food supply. Parasites are thus being introduced 

 primarily to prevent the establishment of the moths in these regions.
