Not illustrated. 1894 Excerpt: favor of the enemies. However, they are worthy of consideration, for the time may come when they will effectually check it. Of the larger animals, two are recorded as feeding on the maggots. In the Country Gentleman for 1864, a correspondent is advised to turn his chickens into his cabbage patch to destroy the maggots. At one end of our experiment plot on Long Island, chickens injured some of the plants soon after they were set out. Later, when the maggots had appeared in full force, the chickens found them, and thousands of them were eaten, but usually the plants were also either pulled up or badly damaged. Thus, on the whole, it is hardly advisable to try to fight this pest with chickens, unless the plants are already beyond recovery. In England, as Miss Ormerod reported in 1884. the Rooks sometimes tear up infested plants and hardly a maggot escapes them. Several insects have been recorded as enemies of the Cabbage Root Maggot and allied insects. In Europe, five different species are recorded as parasites on Anthomyiians. In 1834, Bouchd enumerated the following: Alysia ruficeps, from the pupae of Anthomyia radicum; Alysia manducalor, from the pups of Athomyta denlipes; Microzasler anthomyiarum, from the larvae of Ph irbia ceparum; Figites anthomyiarum, from the pupae of several species of Anthomyia, as dentipes, ftoralis =brassicz), etc. Taschenberg says: "The small Braconid Opiits procerus Wsml. was bred from the larvae hy Mr. Brieschke." All of these insects are minute active wasp-like forms, which doubtless crawl into the earth among the maggots and sting their eggs into the bodies of their helpless victims. Probably none of the above parasites work on the pest in this country; but in 1888 Mr. Gillette discovered that a similar minute Hy...
