It is obtained from cruciferous vegetables such as broccoli, Brussels sprouts, and cabbages. Cruciferous plants such as cabbage produce mustard oil glycosides which give them a stinging flavor. The larvae are found on cabbage, turnip, swede, radish, and other cruciferous crops. Studies suggest that cruciferous vegetables, including cabbage, may have protective effects against colon cancer. The members of the genus are informally known as cruciferous vegetables, cabbages, or mustard plants. Citrus fruits and cruciferous vegetables were also identified as having a possibly protective effect. Cruciferous vegetables are one of the dominant food crops worldwide. Cruciferous vegetables contain glucosinolates, which are under research for their potential to affect cancer. Larvae damage leaves, buds, flowers, and seed buds of cultivated cruciferous plants. Nearly all cruciferous vegetable crops are attacked, but some are favored over others. They can also develop on many species of wild cruciferous plants and on nasturtiums. Most cruciferous weeds can serve as alternate hosts. As a result, growing cruciferous plants during wet seasons can effectively reduce pesticide use. However, infestation seems to occur at lower populations compared to other cruciferous plants.
