Does Floral Farmscaping Differentially Affect a Pest (Pieris rapae) and Its Parasitoids in Broccoli?

The planting of flowering plants together with target crops (floral farmscaping) is becoming increasingly popular among organic vegetable growers in the United States as a promising alternative to chemical pesticides for pest management. Farmscaping flowers attract natural enemies of pests to nectar and pollen, but these same resources may also be attractive to pests. This paper presents results of studies of Pieris rapae abundance and parasitism in broccoli, in Georgia in 2012 as a function of integrated flower treatments. The flower treatments were: (1) broccoli (control), (2) buckwheat, (3) a mixture of two Apiaceae (fennel and dill), and (4) a mixture of two Asteraceae (yarrow and sunflower).
