Insect Pests. 



These observations of Lewis, the most complete yet made on this 

 pest, all tend to show how necessary it is to grub any bushes showing 

 sions of bad infestation and the hand-picking of those showing traces 

 of the disease. 



A rKCULIAR AtTA(_'K OF THE Bl( r BUD MiTE ON EeD CuEEANTS. 



A very curious attack of the big bud mite was recorded by Mr. 



Thomas Edwards of Grange, Gillingham, Kent, in November 1900, 

 on red currant bushes. This was the second he had found (7). 



Later Mr. Edwards wrote me that he had had such a bad attack 

 of big bud in the black currants that he had destroyed them by 

 burning. The attacked red currants were raised by himself and 

 not imported. 



The resulting disease caused by the mites presented such very 

 marked features that I decided to send the acari to Dr. Nalepa, of 

 Vienna, who reported that they were undoubtedly the Uriojihycs riUs, 

 Nalepa, which causes tlie " big bud " in black currants.
