Abstract/Contents:"Fifteen buffalograss, Buchloe dactyloides (Nutt.) Engelm., cultivars that are entered in the 1996 National Buffalograss Test conducted by the USDA National Turfgrass Evaluation Program were evaluated for resistance to the fall armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae). 'Tifway' bermudagrass, Cynodon dactylon x C. transvaalensis (Burtt-Davy), was included in the study as a susceptible host for comparison of feeding activity and developmental time. Each of the Buchloe cultivars except UCR-95 and 'Stampede' provided significantly higher antibiosis (greater than 79%) of the confined larvae. Additionally, it took much longer for surviving individuals to pupate and reach the adult stage on most of these cultivars. All of the resistant cultivars are tetraploid or hexaploid with 'Bam 1000', 'Bison', 'Bonnie Brae', 'Cody', 'Midget', 'Prairie', 'Tatanka', 'Texoka', 86-61 and 378 providing greater than 95% mortality of the confined larvae before pupation. The susceptible UCR-95 and Stampede are both diploid. Larval mortality on these two cultivars was never significantly higher than on Tifway bermudagrass. The tetraploid B. dactyloides had varying degrees of resistance whereas the diploids were susceptible."
