| Abstract/Contents: | "University of Georgia researchers are evaluating the potential for resistance to multiple insect pests among turfgrasses for the southeastern United States. Genetic resistance to major insect pests can reduce pesticide use and simplify management of turfgrass cultivars. Laboratory, greenhouse and field studies were conducted to identify resistance among bermudagrass, zoysiagrass, centipedegrass and seashore paspalum selections to the fall armyworm, twolined spittlebug, and tawny and southern mole crickets. Among warm-season grasses, fall armyworm larval weight gain and survival were greatly reduced on several zoysiagrasses. Development of surviving larvae on these grasses averaged as much as 44% longer than on susceptible grasses. Cavalier demonstrated high levels of resistance. Palisades were moderately resistant to the armyworm. Seashore paspalums were very susceptible. TifSport and an experimental 97-8 bermudagrass demonstrated improved resistance to this pest. All centipedegrasses tested were highly susceptible to twolined spittlebug followed by bermudagrasses, seashore paspalums, and zoysiagrasses. Improved resistance to the spittlebug among paspalums was observed on Sea Isle 2000, Mauna Kea, HI-1 and 561-79. In field tests Emerald zoysiagrass was tolerant of spittlebug injury. None of the tested genotypes were hightly resistant to tawny mole cricket injury. TifSport and 561-79 (Argentine) seashore paspalum were most tolerant." |
