1 8 First Report on Economic Zoology. 
Mustard should always therefore be drilled far apart when grown 
ior seed ; more than a foot should be allowed between each row. Not 
only can the crop then be easily borse-lioed, but special machines can 
be taken across the fields between the rows to catch the beetles. 
W ooden scoops, with tar or soft soap smeared over the insides, may 
be arranged so as to be pulled through the field, either by hand or 
horse-power, and so collect the beetles. 
the early spraying with some arsenical wash so as to kill the 
larvae and beetles is, however, most to be recommended.

An Enquiry re Bud Mites ( Eriophyes ribis , Nalepa) in 
Black Currant Bushes. 
A correspondent of the Board of Agriculture living at Suckley 
sent an enquiry regarding the stacking of diseased black currant 
bushes and the subsequent escape of the Bud Mites {Eriophyes ribis). 
Information was sent that it is best to burn the cuttings from the 
black currant bushes infested with the “ Big Bud ” mite. There are 
several points not yet settled in the life-history of this pest, notably 
how long the egg stage lasts ; under the circumstances, it is best to 
destroy all infested parts, as ova will be found at most times of the 
year in the buds. 
The probability is, however, that if the black currant faggots were 
stacked in the centre of the rick of other wood, that the acari would 
die out and the eggs become destroyed ; but, owing to the great 
increase and ravages of this pest, it is best to be on the safe side and 
to recommend the burning of the infested cuttings, which cannot be 
■of much value as wood. 
The most complete life-history of this serious pest has recently 
appeared in the Journal of the S. E. Agricultural College , by Mr. E. J. 
Lewis (No. 11, pp. 55 to 80 (1902)). 
The Apple Blossom Weevil. 
{Anthonomus pomorum, Linn.) 
Some apple blossoms sent by a correspondent of the Board from 
Tottenham on July 20th were attacked by the Apple Blossom 
Weevil {Anthonomus pomorum). The blossoms all contained the 
mature beetles, ready to emerge. These beetles feed upon the leaves
