The Acadian Entomological Society 



This society which until 1921 was known as the Entomological Society of

 cial Department of Agriculture for Xova Scotia contributed the sum of S300 

 in 1921 and 8400 in 1922 towards assisting the society in its work, particularly 

 in connection with its annual publications. These transactions contain very- 

 valuable contributions: the last number (No. 8) comprised 182 pages and

NEW BRUNSWICK 



Federal 



In 1914, a small portable structure was used as the federal laboratory, 

 space for which was provided on the grounds of the University of New Bruns- 

 wick at Fredericton. The following year (1915) a permanent brick building 

 of two stories was erected, an in 1917 an excellent insectary was added. 

 The work at this laboratory was under the joint direction of ^Messrs. J. D. 

 Tothill and L. S. ]\IcLaine, until 1918 when the latter officer was transferred to 

 Ottawa. 



The officers attached to the Fredericton laboratory have made special 

 studies of the natural control of native insects and have also had charge of the 

 introduction and establishment in eastern Canada of the parasitic and preda- 

 ceous enemies of the Brown-tail and the Gipsy Moths. A bulletin on these 

 two latter insects prepared by IVIessrs Tothill and McLaine was published by 

 the Provincial Department of Agriculture in 1914. The natural control of the 

 Fall Webworm, Hijphantria cunea Dru, the Forest Tent Caterpillar, Malaco- 

 soma disstria Hbn., and the Spruce Budworm, Harmologa fumiferana Clem, 

 was specially studied b}' Dr. Tothill and his assistants. An important bulletin 

 of 107 pages, entitled, "The Natural Control of the Fall Webworm" was 

 published in 1922. In 191G, Dr. Tothill studied the natural control of the 

 Oj^ster-shell Scale, Lepidosaphes ulmi L.; about 10,000 egg masses from several 

 provinces were examined and it was found that the mite, Hemisar copies mains 

 Shimer w as the most important single factor in control. An investigation on 

 the natural control of the White-marked Tussock moth, Hemerocampa leucostig- 

 ma S. & A. was commenced in 1917, and the results published by Mr. A. G. 

 Dustan in 1923. In the same year, a study of the natural control of the 

 Cherry-tree Ugly-nest Tortricid, Caccecia cerasivorana Fitch, was completed 

 by Mr. A. B. Baird and a paper resulting therefrom published in 1918. More .
