Cabbage Fly

( Entom.) An insect ( Anthomyia bras sicæ ) of the same family as the house-fly, and belonging to a very large genus, many of whose species are injurious to plants. The maggots are found in summer on the roots and lower stems of the cabbage and similar plants. Rotation of crops is probably the best method of prevention, but the pupæ may be destroyed by drawing away the earth around the roots of cabbages, while the larvæ may be killed by spraying with lime water. Cabbage-Moth, n. ( Entom.) A species of moth ( Mamestra bra ica ) whose larvæ attacks the leaves of of the cabbage and turnip, and is sometimes very destructive. The perfect insect is of a rich mottled brown color, with beautiful markings. The grubs may be picked from the cabbages, or their ascent prevented by making a ring in the ground with spirit of tar or gas-lime.
