Crucifers ( cabbage, cauliflower, broccoli, collards, mustard, turnip, etc) are attacked by 30 or more species of insects. Identification of insect stages, damage and natural enemies is the first, but critical step in Integrated Pest Management. This poster illustrates some of the major insect pests, depicts their life stages, and presents their feeding damage, so that a field professional can employ IPM strategies and tactics. These may consist of understanding biology and life histories, implementing trapping and monitoring systems, using sampling techniques to assess economic and action thresholds, and selecting and applying insecticides in an effective manner.
Species 1: Lepidoptera Noctuidae Trichoplusia ni (cabbage looper)
Species 2: Lepidoptera Yponomeutidae Plutella xylostella (diamondback moth)
Species 3: Heteroptera Pentatomidae Murgantia histrionica (harlequin bug)
Keywords: vegetable insects, identification
