34 PROTECTION OF PLANTS — 1923-24 



Mr. Joseph Perrin, of McNabs Island, has assisted the Division of Foreign 

 Pests Suppression in the inspection of imported nursery stock at the port of 

 Hahfax since October 1913. Mr. Perrin has continued to take a keen interest 

 in entomology, particularly in lepidoptera, and has brought together a collect- 

 ion of the local species which is undoubtedly of considerable importance.

The staff of the Provincial Entomologist, Dr. W. H. Brittain, has been 

 added to during recent years and an entomological laboratory established 

 at Wolfville. This laboratory has been mainly concerned in problems relating 

 to fruit growing. In all of this work a close co-operation with the federal 

 service has been maintained. At Truro, studies of insects attacking vegetables 

 were undertaken, the Cabbage Root maggot, Hylemya brassicce Bouche, being 

 especially investigated. For a period of nine years the latter insect was under 

 close observation and the details of its control under Nova Scotia conditions 

 thoroughly worked out. 



The Department has published valuable bulletins, particularly on the 

 Apple Maggot, the Green Apple Bug, the Apple Sucker, and the Potato Stem 

 Borer. Recently , material has been collected for a handbook of Nova Scotia 

 insects and it is expected that this publication will contain an illustration of 

 every insect included. 



In connection with the Brown-tail Moth winter work directed by the fede- 

 ral Entomological Branch, the Department of Agriculture for Nova Scotia 

 has contributed officers to assist in this work.

Several changes have been made in the legislation relating to insect pests 

 •during the past ten years. The Provincial Entomologist is the executive 

 officer appointed for the purpose of carrying out the regulations under the act. 

 The "Foul Brood Act" 1916, dealing with the prevention and treatment of 

 diseases among bees is also administered b}- the Provincial Entomologist. 



Soon after the discovery of the San Jose Scale in Nova Scotia in 1912, 

 the Department established fumigation stations at Dibgy and Truro, for the 

 purpose of treating all nursery stock entering the province. In 1920, these 

 stations were closed and all shipments subject to fumigation were, thereafter, 

 treated at a federal station. The province then required all shipments for 

 Nova Scotia from provinces known to be infested by the San Jose Scale, to be 

 fumigated before shipment under the direction of a provincial officer. In 1923, 

 an order-in council was passed amending the regulations to conform with the 

 federal regulations under the Destructive Insect and Pest Act dealing with the 

 importation of plants and plant products. 



In addition to the regular course in entomology given at the college, by the 

 Provincial Entomologist and Professor of Entomology, short courses have been 

 held in various parts of the province and at these the control of farm pests has 

 been explained directly to the farmers. These short courses have done much 

 to educate those in attendance in matters relating to insect control and many 

 are putting the knowledge thus gained into practice.
