Orchard and Bush Fruit Pests, [march, 



to be in the colour of the head. Both black and creamy- 

 headed forms have been bred from the apple, but there is no 

 doubt that the hawthorn feeder and the apple pith-moth are 

 distinct. So far I have failed to trace this serious enemy of 

 apple growers in England outside Kent and Sussex, wit)\ 

 the exception of a single example of its occurrence near 

 Criccieth in North Wales on young stock imported, I believe, 

 from Chester. So harmful is the pith moth in a young 

 plantation that it is well for growers to keep a sharp look- 

 out for it in any newly-purchased stock. I can find no record 

 of it as a pest in Continental Europe or in America ; in any case 

 I am sure, from what Dr. L. O. Howard tells me, it is not known 

 in the latter country. Its home in Britain seems to be the 

 south-eastern and southern area of England, but owing to its 

 obscure way of working it may have been overlooked else- 

 where. I have, however, failed to trace it in Herefordshire, 

 Worcestershire, Devon, Cambridgeshire, and other fruit 

 counties, and Messrs. Newstead, Warburton, and Collinge do 

 not seem to record it in any of their reports. The example 

 recorded by Carpenter was from near Dublin. 



Plum and CJierry Tree Borer. — The plum tree and cherry 

 tree borer {Sesamia ivoeberana) still persists in the Sitting- 

 bourne district of Kent, but has been kept down by constant 

 supervision and removal of attacked parts. Two attacks were 

 reported in 1906. 



Pear Leaf Miner. — Two interesting Tineid moths have 

 occurred in Worcestershire. One of these, the pear leaf miner 

 [Cemiostonia scitella), was reported from that county, and the 

 infested wall tree was found to have every leaf destroyed. This 

 small moth occurs all over Britain, and now and again seems to 

 increase so rapidly that it becomes a serious strain on the 

 attacked tree. Previous damage has been recorded from Scot- 

 land and from Cambridgeshire. 



Cherry Fruit Moth. — The other Tineid pest is of great interest, 

 namely, the cherry fruit moth {Argyrethesia conjugella). This 

 serious fruit destroyer has been previously recorded by Mr. White- 

 head from Kent. For some thirteen years I have failed to detect 

 it in Kentish cherry orchards. It has, however, occurred during 

 the past season in one large cherry plantation near Stourport.
