Greenhouse experiments were conducted to determine how interactions between fall armyworm, Steinernema carpocapsae, and Neotyphodium endophytes influece competitive interactions between grasses and dandelions. Four independent 2x2x2 factorial experiments were performed, two with perennial ryegrass and two with tall fescue each growing in pots with dandelion. Plant tillers(grasses) or leaves (dandelion) and above-ground biomass were measured and compared after allowing time for regrowth. Results of these experiments will be presented and discussed.
Species 1: Lepidoptera Noctuidae Spodoptera frugiperda (Fall Armyworm)
Species 2: (entomopathogenic nematode)
Keywords: multi-trophic interaction, biological control
