At Vancouver, B. C, we have a laboratory for forest insect 

 investigations. Mr. R. N. Chrystal, the field officer in charge, 

 has been studying in particular the insects destroying conifers 

 in Stanley Park, especially species of Chermes and one or two 

 lepidopterous larvae. Under the direction of Mr. Swaine he has 

 continued the latter's observations on the ScolytidcB and other 

 timber destroying beetles in the province. 



All the work is directed from Ottawa where the offices of the 

 Entomological Branch are situated. Mr. Arthur Gibson is 

 Chief Assistant Entomologist and in addition to assisting in 

 the regular executive work of the Branch and the administration 

 of the provisions of the Destructive Insect and Pest Act, he 

 has charge of the work on insects affecting field crops, garden 

 and greenhouse and stored products. Mr. Gibson's work on 

 the Noctuidae is well known and during the last few years he 

 has been investigating chiefly the control of locusts and root 

 maggots. Mr. J. M. Swaine is Assistant Entomologist in 

 charge of Forest Insect Investigations. The extensive coni- 

 ferous forests of Canada naturally offer great opportunities for 

 such investigatory work and particular attention has been paid 

 to serious and widespread injuries by Scolytid beetles in British 

 Columbia. For a number of years Mr. Swaine has been 

 making taxonomic and biological studies of the Scolytidae and 

 we hope to commence the publication of the results of this 

 study shortly. Our studies of the spruce budworm, exclusive 

 of its natural control, have been completed and in addition much 

 ground work has been accomplished in the study of insects 

 affecting shade trees. Mr. Germain Beaulieu has charge of 

 the collections and the recent establishment of a national 

 collection of insects has enabled us to give this aspect of our 

 work the recognition it deserves. 



The Dominion work of preventing the introduction and 

 spread of injurious insects is carried on under the Destructive 

 Insect and Pest Act, 1910. Under the Regulations of this Act 

 the importation of all nursery stock, etc., is governed. Nursery 

 stock may be imported only during certain periods through 

 prescribed ports of entry at which fumigation and inspection 

 stations are provided. Importers are required to give notice 

 of the ordering and receipt of those classes of trees and plants 

 subject to inspection. Quarantine regulations also prohibit
