Brassica crops are produced in Florida from fall through spring including, bok choy, broccoli, cauliflower, collards, cabbage, mustard, radish, and turnips. Brassica crops vary in their features such as leaf characters and architecture, and these can influence DBM preference for feeding and/or oviposition. Basic research is essential to understand the resources in favor of more sustainable pest management. In this study, the effect of four different brassica types on DBM occurrence was studied green cabbage (Bravo), red cabbage (Red Jewel), Napa cabbage (Chinese Pacifiko, and collards (Top Bunch), during the Spring 2022 season in three cabbage production sites in Florida (Wimauma, Belle Glade, and Hastings). Crops were sampled three, six and nine weeks after planting Damage pattern, plant weight, insects per plant, and insects per plant biomass (100g) were measured to evaluate DBM infestation.
