Insect Pests. 



It is most abundaBt in Surrey. A correspondent, writing from 

 Woking, states that lie is much troubled with it, and that he had 

 used lots of mixtures and kept brushing in summer, but without 

 success, liecently I learn that this nurseryman is coping with the 

 root form. Numerous inquiries have come from Cambridgeshire, 

 Huntingdonshire, Norfolk, Suffolk, Cheshire, Yorkshire, Sussex, 

 Hampshire and Oxfordshire. In Wales I have found it in abundance 

 amonost young trees imported from the Midlands at Criccieth, also at 

 Carnarvon and Bangor ; in Monmouthshire it was noticed in some 



gardens. This record of locali- 

 ties could be still further 

 increased. 



Besides being known under 

 the popular name of Woolly 

 Aphis, it is frequently spoken 

 of as " American Blight." The 

 reason for this is ditticult to 

 understand, for it is undoubt- 

 edly European, and we are 

 also equally certain that it 

 was introduced into America, 

 just as it has been into Africa 

 and Australasia, with imported 

 stock. 



It attacks practically all 

 varieties of apples in this 

 country. In Australia (5 and 

 6) it is found that apiples 

 grafted on Northern Spy and 

 Majetin stocks do not sutler 

 from the ground form, and 

 these are now solely used for 

 this purpose. Mr. Lounsbury, Coverument Biologist at the Cape, 

 tells me that no apples unless on these stocks are allowed to be 

 imported into Cape Colony, and that their i'> lud to be 



tlie same there as elsewhere. The " May ^ uiuue in 



Cape Colony (9). This is a very importan t' these 



stocks are used in this country. Nurserynie, e spoken 



to about the subject ha\'e expressed their opin .luversely, but 



I am not aware that anyone has tried thein in this countrv, and 

 until this is done one must naturally believe not oiilv wliat such 

 great experts as Mr. French, the (lovernment Entomologist of A'ictoria,
