. The vegetable industry in New York state ... Vegetables; Gardening. 1342 The Vegetable Iadustky in Xew York State the plant, eating out small channels along the underground part of the stem and the roots. If the maggots are present in any numbers the plant will begin to wilt in a few- days and eventually will die. In three or four weeks the maggots become full-grown and change to brown oval objects termed puparia, which are visually an inch or so below the surface of the soil. In about two weeks an adult fly emerges from each of the puparia and is soon ready to deposit eggs for a second brood. The insect passes the winter as a puparium in the soil. This insect is a serious pest of cabbage plants in the seed-bed aa well as of plants after they are set in the field. Control. Plants in the seed-bed may be protected by setting up boards on edge about the bed and then nailing muslin across the top. The dirt should be heaped up around the lower edges of the boards in order to prevent the flies from crawling under and gaining access to the plants. The muslin should be removed about ten days before transplanting time so as to harden the plants and prepare them for set- ting in the field. Plants in the field are best protected by placing hexagonal tarred paper cards about the stems close to the soil. These cards can be purchased ready cut from Joseph Harris Co., Coldwater, IST. Y., at $ per thousand. They can be quickly and economically applied in the field (Fig. 396)..
