The Fight Against Insects * 



Dr. C. Gordoa Hewill. Domiiion EitonioUgiit, Ottawa 



The three methods in which the Dc^part- 

 ment of Agriculture, of the Federal Gov- 

 ernment is dealing -H-ith tlie serious problem 

 of insect pests are by legislation, by investi- 

 gation and by ediu'ation. When it is real- 

 ized that about fiftv per cent of our most 

 injurious insects have been introduces] into 

 Canada from other countries, the necessity 

 of taking steps to prevent the introduction 

 of further nests, and the spread of serious 

 nests already within our borders into re- 

 gions of Canada in which they do not occur, 

 will be readily understood. 



The disooverv of winter nests of the 

 Rrown-tai' Moth on nurserv stock imported 

 from France in 1909 was chieflv responsible 

 for the passage of The Destructive Insect 

 and Pest Act of 1910. Dnring the first year 

 of o'lr work under the Act over two and a 

 half million plants and trees in Eastern 

 Canada alone were examined and three 

 hundred and ten winter webs of the Brown- 

 tiil Moth were found. When you realize 

 that each of these winter nests may contain 

 two or thre" hundred caterpillars of the 

 Tirown-tnil Moth the importance of th''s 

 'vo^-k is obvious. La.st .season nearly four 

 million plants were inspected in Canada. 



THE BROWN-T.ML MOTH 



In addition to the fumigation and inspec- 

 tion of imported trees and vegetation class- 

 ed as nursery stock, a camoaign against 

 the Brown-tail Moth, which was first dis- 

 covered in Nova Scotia in 1907, is being 

 earned on by the Federal Denartment of 

 Agriculture, in cooperation with the Pro- 

 vincial Bepartments of Agriculture of Nova 

 Scotia and New Brunswick. To those ac- 

 quainted with the ravages of the Broivn-tail 

 and Gipsy Moth.s in the New England 

 States, where these moths were allowed to 

 spread, the necessity of taking all no.ssible 

 means to obtain the control of this insect 

 m Canada needs no emphasising. In the 

 State of Massachusetts alone over a million 

 dollars a year are being spent in the at- 

 tempts to control these two nests. The 

 control will never be obtained! by artificial 

 means, and resource has now been made to 

 the importation of the parasites of these 

 in.sects from the countries in which they 

 are native, in the hone that ultimately with 

 the aid of man's assistance, nature will be 

 able to obtain the control. 



In Nova .Scotia the insect is distributed 

 through the four counties of Yarmouth, 

 Dicby, Annapolis and Kings, and the suit- 

 ability of the country to the propagation 

 of the insect is indicated by the fact that 

 in one case a winter nest or web was found 

 to contain over eighteen hundred caterpil- 

 lars. The insect infests not only the apple 

 hut also wild thorn, rose, oak and other 

 trees. Last spring, for the first time, the 

 in.sect was found to have spread into New 

 Brunswick from Maine, along the coa.st of 

 wTiich it is prevalent. We are now making 

 attempts to anticipate its arrival in large 

 numbers by introducing its parasites and 

 establishing these on the nat<ive in.sect be- 

 fore it arrives in force. Its abundance in 

 Nova Scotia and New Brunswick is such 

 that, unless it spreads seriouslv into the 

 wild bush and forest, we shall be able, I 

 venture to hope, if we leave no stones un- 

 turned, to keep it under control and to pre- 

 vent it from attaining such dangeroTis pro- 

 portions as it has obtained in the New Eng- 

 land States.
