A New Apple Pest. 



[Nov., 



a season of heavy laying, some of our dual purpose breeds will 

 show an increase in carcass weight, and consequently a higher 

 killing price would be obtained. Similarly the manure produced 

 if properly stored and used is a most valuable commodity, and 

 its value should certainly be credited to the pen performance. 

 An ordinary pen, fed as the Harper Adams Laying Trial birds 

 are fed, will produce a quarter of a ton of manure per annum 

 showing the following approximate analysis : — water 72-6 per 

 cent., nitrogen 1-42 per cent., phosphoric acid 201 per cent., 

 potash 0'42 per cent. Expressed another way each pen of six 

 hens competing at the trials, produces roughly between 7 and 

 8 lb. of nitrogen. 10 lb. of phosphoric acid and lb. of potash. 

 "When it is remembered that this year the birds may be expected 

 to produce nearly one hundred tons of this highly concentrated 

 manure, to disregard it in relation to feeding costs appears to 

 be a mistake. The unsatisfactory state, in which the storage 

 and use of poultry manure is at present, opens up another 

 question outside the scope of this paper.

A NEW APPLE PEST. 



J. C. F. Fryer, M.A., 

 Pathological Laboratory, Ministry of Agriculture, Harpenden. 



A report has recently become current in horticultural circles 

 of the appearance in England of a weevil allied to the Apple 

 Blossom Weevil but even more destructive in its habits, and it 

 may therefore be of interest to Journal readers to give a few 

 details with regard to the discovery. 



In the spring of 1921 Mr. F. R. Petherbridge, of Cambridge 

 (Adviser to the East Anglian Province) found on the borders of 

 Norfolk one or two weevil larvae resembling those of the Apple 

 Blossom Weevil, but feeding in the unexpanded leaf or truss buds 

 of apple and not in the actual blossom buds themselves. As 

 soon as one of these larva?, after pupating, had turned into an 

 adult weevil, it was evident that a species different from the 

 Blossom Weevil had been obtained. In August of the same 

 year Mr. Harwood, when collecting beetles in Kent, obtained 

 under bark in company with Apple Blossom Weevils an example 

 of the same kind of beetle as had previously been reared by Mr. 

 Petherbridge. Both the Kent and Norfolk specimens have since 

 been identified as a species of weevil (Anthonomus cinctus, 

 Kollar, =A. pyri. Boh.) not previously recorded in Great Britain 

 and therefore of course without any English name.
