Clear away brush piles, grass thickets, rubbish, and any other material that may serve as insulation during cold temperatures.

Mulching of seedbeds will provide habitat for these predators. Monitor and Some type of control is necessary to avoid the trap crop becoming a source of infestation.

Plant a small acreage of a non-market preferred host such as turnip, kale or mustard in the spring before market crops are grown to serve as a trap crop.

Adults are usually the only stage to survive winter conditions.

Seek shelter during cold temperatures in winter by hiding under grass cover, rubbish piles, and other insulating materials.

No diapause, but life cycles are extended in the winter, which results in low populations.

Pierce host with mouthparts and extract sap. Coloration goes from pale orange to more defined colors in older stages. Usually laid in rows of two in groups of around 12.

Eggs… (4-29 Days) White and black striped, keg shaped.

Males produce aggregation pheromone to attract other feeding individuals.Incorporates g lucosinolates from crucifer plants, which are undesirable to birds.Younger plants have a lower threshold for damage than younger plants. Browning, wilting, and eventual death of host plants can occur under intense feeding conditions.Has ability to destroy entire crops if left uncontrolled.Can also be seen on tomato, potato, eggplant, okra, bean, asparagus, beets, and fruit trees. Preferred crops include: horseradish, cabbage, cauliflower, collards, mustard, Brussels sprouts, turnip, kohlrabi and radish.
