SiR, — I have the honour to submit herewith my fourth Annual Report of the 

 work of the Division of Entomology covering the year beginning April 1, 1912, and 

 ending March 31, 1913. A summary of the chief lines of work tipon which we have 

 been engaged during the above period has been submitted to you separately and in 

 the present report a more detailed account of our investigations and of the depreda- 

 tions of those insects which were unusually abundant and injurious is given for the 

 use of tbose desiring more information on the subject. 



The most notable advance in our work during the past year has been the exten- 

 sion of our sphere of investigation and assistance by the establishment of field labora- 

 tories in certain of the provinces. The existence of many pressing problems which 

 eould only be investigated in the regions in which they occurred, rendered this 

 development necessary. The expansion of our organization in this direction has not 

 only enabled us to commence a series of thorough investigations on certain insect 

 pests, which will be specified later, but it has placed the Division in direct contact 

 with the farmer and the fruit grower with the result that our officers located at the 

 field laboratories are able personally to advise enquirers in regard to injuries due to 

 insect pests, and by their attendance at meetings to interest farmers in methods of 

 insect control. Still more important is the fact that on the receipt of reports of 

 serious injuries we are able in many cases to instruct our field officer in the particular 

 district to visit the farmer, investigate and if possible advise. The value of such 

 immediate and personal contact between the Division and the farmer is only too 

 evident; it is the most helpful form of assistance we can render. The appreciation 

 with which this extension of our work has been met and the valuable results already 

 obtained indicate the desirability of a continued development of the policy. 



For the sake of convenience the report of our work may be considered under the 

 following sections : — 



1. The Administration of the Destructive Insect and Pest Act, including: 



(a) Inspection and fumigation of imported nursery stock, etc. 

 (&) Field work against the Brown-tail Moth and parasite work. 



2. Insects affecting field crops. 



3. Insects affecting fruit crops. 



4. Insects affecting forest and shade trees. 



5. Insects affecting domestic animals and man. 



6. Insects affecting garden and greenhouse. 



7. Apiculture. 



8. Miscellaneous.
