MANGOLD. 
larva of the little Piophila pusilla, and, judging by the great attraction 
decay has for many of these Flies, may very possibly be attracted in 
part by the richly-manured land. However this may be, I have so 
many specimens of the maggots carefully secured in the earth in 
which they buried themselves that I shall hope to be able to name the 
species in the coming season. 
MANGOLD. 
Mangold and Beet Fly. Anthomyia Beta, Curtis. 
Beet Fly and pupa, mag. and nat. size ; head and eggs, mag. 
During the past season the Mangold Leaf-maggot has been de¬ 
structive at various places, but unfortunately scarcely any notes have 
been sent in of treatment to prevent or check it. 
The great point appears to be to gain such a strong healthy growth 
as may carry the Mangold over attack; and in the following observa¬ 
tion autumn cultivation is noted as having proved serviceable. 
Mr. Jabez Turner, of Norman Cross, Peterborough, in reply to my 
enquiries, favoured me with information that his plan is to use a 
mixture of farmyard manure, applied in the autumn as soon after 
harvest as possible, and a fair dressing of superphosphate, &c., put on 
with the seed. He further notes :—“ I have never suffered from Fly 
in a Mangold crop, as I think, if the plants are well fed and nourished, 
the growth is too strong for the enemy to do much damage. 
“ I may remark that the crop of Mangolds this season in the Fen 
district, where many are grown, is very fine, and the plants look 
remarkably healthy.” 
This communication, taken in connection with the following (which 
I am also kindly permitted to use) from the Hon. Cecil Parker, Eaton 
Estate Office, Eccleston, Cheshire, appear to me to suggest a good 
deal:—
