Aphid and Looper Contamination of Broccoli and Cauliflower (2002)

Report to the Oregon Processed Vegetable Commission

Dan McGrath
OSU Dept of Horticulture

Five insects contaminate broccoli in the Willamette Valley: cabbage loopers (Trichoplusia ni), cabbage white butterfly larvae (Pieris rapae), diamondback moth (Marrtestra aphids (Brevicoryne brassicae). Broccoli is inspected very closely before it is accepted for processing. Low levels of insect contamination result in the rejection of truckloads of harvested broccoli by processor quality assurance programs and thousands of dollars of loss to growers.
