ANNUAL REPORT OF NEW TORE 
CABBAGE-FLY. MAGGOT. ITS HABITS. 
ful as such a provision of nature would he, it is the most probable 
conclusion I am able to arrive at from the facts observed. 
The transformations and habits and the remedies for this group 
of insects will bo found fully stated under the Striped flea-beetle. 
Cabbage-fly and worm, Anthomyia Brassicw, Bouchd (Diptera Muscidee.) 
Tho roots of tho cabbage orodod and bored, and the young plants hereby often killed by 
a white maggot having its flattened hind end margined nround with minute toeth, whereof 
the lower two are largor and their tips notohed; the pupa underground, producing an ash- 
gray fly, having on the hind body a black stripo along the middle and a narrower black 
band upon each of the sutures. 
The young plants of the cabbage are liable to be destroyed by 
maggots excoriating the surface and boring iuto the interior of the 
roots. In the years 1856 and 1857 they were very destructive in 
different parts of the State, appearing quite early in the season 
and attacking the young plants in the seed bed, destroying them 
so extensively that in many neighborhoods it was impossible to 
obtain plants for setting out. My attention was first called to this 
insect, by receiving from Prof. Wm. Hopkins, then of Genesee 
College, stems of young cabbages containing these maggots, which 
it was stated, were at that date, June 16th, 1856, ruining all the 
cabbage and cauliflower plants in his and his neighbors’ gardens. 
From pupa; which were also remitted mo a fortnight later, I ob¬ 
tained flics, answering to the description given of the European 
Anthomyia Brassicce of Bouche, the larvte also coinciding with tho 
characters stated as pertaining to the larvae of that species; where¬ 
fore I make no doubt it is the same. It continues to infest the 
roots through the season, which arc better able to withstand its 
attacks, the more they are grown. At the time of gathering the 
cabbages in autumn I have repeatedly noticed this maggot, bur¬ 
rowed in the bark of the root, or, in two or three instances just 
beginning to enter it, with the end of its body projecting stiffly 
out, like a peg driven in half its length. 
These maggots infest the turnip and ruta baga also, mining an 
irregular burrow in tho interior, or inhabiting eroded spots upon 
their outer surface. Sometimes a small roughened spot is seen, 
appearing like a crack in the skin of tho turnip, with its edges 
rough and ragged and turned outward, and on pairing oil tins 
roughened spot a plump white maggot is come upon, lying in a 
cavity it has there made for itself. At other times a larger eroded 
spot occurs, which is filled with wet and slimy dirt. On remov
