Eighteen species and cultivars of warm-season and 14 of cool-season turfgrasses were evaluated for resistance to lawn cutworm, Spodoptera depravata (Butler) (Lepidoptera: Noctuidae), larvae in the laboratory. Larvae fed on cool-season turfgrass leaves showed higher survival rates than those fed on warm-season turfgrass leaves. All larvae fed on leaves of Eremochloa ophiuroides and Zoysiagrass ‘Emerald’ died within 6 and 8th days, respectively. All larvae fed on warm-season turfgrass leaves exhibited lower weights (19.9–101.2 mg) as compared to those fed on cool-season turfgrass leaves (193.6–273.6 mg) during a 10 day evaluation. Larval development period was longer when fed on warm-season turfgrass leaves (21.5–31.9 days) than on cool-season turfgrass leaves (17.0–19.5 days). Extended developmental periods were observed in cutworm larvae especially on leaves of Hybrid Zoysia ‘Miyako’, Z. japonica ‘Himeno’, native, Z. matrella, Cynodon dactylon ‘Sahara’, and Stenotaphrum secundatum.
