Habitat composed of flowering plants in or around crop fields has been shown to attract insects that prey upon or parasitize crop pests. The goal of this study was to identify a floral habitat suitable to North Carolina that could enhance insect pest management on organic farms. Visual observations of a range of flower types were conducted in the summers of 2004 and 2005. Sticky traps were also placed in the center of each flower plot to monitor insect activity. The most attractive plants to beneficial insects were fennel, Foeniculum vulgare, Shasta daisy, Leucanthemum x superbum, and buckwheat, Fagopyrum esculentum. These plants were grown in a greenhouse and their flowers were presented to individual female Trichogramma egg wasps to determine if longevity and fecundity differed when compared to wasps provided water or honey-water.
