MANGOLD FLY.

havoc in very large country gardens, where the extent of ground 
allows a great deal of what may be called spare land, it is very difficult 
to remedy the evil. Where there is storage of decaying leaves, and 
all the miscellaneous matters which pass under the name of rubbish, 
on outlying bits of garden, there equally surely is a head-quarters for 
multiplication of millepedes, and a centre whence they will spread at 
leisure, as well as pass by carriage in compost to the neighbouring 
ground. For history and prevention see previous Keports. 
MANGOLD. 
Mangold Fly. Anthoynyia beta, Curtis. 
Anthomyia bet.®. 
Mangold Fly and pupa, mag. and nat. size; head and eggs, magnified. 
The following note was sent me by Mr. John Page, of Yieldingtree, 
near Stourbridge, regarding a stimulating dressing which he had found 
useful in bringing Mangolds which were attacked by leaf-maggot 
satisfactorily through attack. 
Mr. Page had forwarded me specimens of Mangold-leaves injured 
by the maggot, together with enquiries as to what treatment might be 
serviceable ; and on Aug. 18th he reported further:— 
“ Eeferring to the attack of Mangold maggot, I am happy to say it 
passed off without materially injuring the crop. I applied a dressing 
of 1 cwt. of nitrate of soda, 8 cwt. salt, 2 cwt. kainite and soot, per 
acre, which forced the plants into active growth, and they are now a 
splendid crop.” 
In attacks of this kind, where the crop perishes simply from 
exhaustion in consequence of the leafage being destroyed by the 
maggots faster than the growing powers of the plants can replace it, a 
dressing like the above, which will come into action with the first 
shower and cause immediate growth, is sure to be of use.
