OF 



OBSERVATIONS OF ATTACK OF TURNIP FLY IN 1881. 



Turnip " Fly." Phyllotreta nemorum. 



1 3, P. nemorum ; 4, 5, eggs ; 6 9, maggots ; 10, 11, pupa ; all nat. size 

 and magnified. 



The unusually severe attack of Turnip Fly in the season of 1881 

 to a large amount of the Swedes and Turnips both in England and 

 Scotland, and the attention consequently directed to the subject, 

 suggested that, if whilst the amount of injury was still fresh in the 

 memory, those possessed of information would give details of the 

 extent of the losses sustained, and of any means found practically of 

 use either in preventing or remedying attack, such information would 

 be of great service to us all in drawing observation generally to 

 the importance of the losses caused by this farm pest, as well as in 

 showing that means lying in the ordinary measures of good cultivation 

 are of service in checking the evil. 



With this view circulars requesting information were forwarded to 

 agriculturists, and others interested in the subject, in various localities 

 throughout the country, which have been replied to far more minutely 

 and fully than I ventured to hope ; and, whilst I express my thanks to 

 all those who have so courteously and ably assisted me, I wish 

 especially to acknowledge the valuable help kindly afforded me, 

 through the aid of Mr. Dent-Dent, President of the Eoyal Agri- 

 cultural Society ; also by Mr. C. Whitehead, Chairman of the Seeds and 

 Plant Diseases Committee ; and by Mr. J. H. Arkwright, of Hampton 

 Court, Herefordshire, on the Council of the same Society ; and by Mr. 

 F. N. Menzies, Secretary of the Highland and Agricultural Society of 

 Scotland.
