| Abstract/Contents: | "The damage potential, phenology and dispersion Trigonotylus doddi (Distant) were investigated in forage-type bermudagrass, Cynodon dactylon (L.) Pers. In a greenhouse study, adults fed on leaves, leaf whorls, and stems resulting in leaf chlorosis and severe stunting of stems. Stem height and plant dry matter production declined substantially as adult density increased. Seasonal trends of nymphs and adults were similar in all fields with population peaks occurring in late May through June and in September through October. Nymphal and adult populations were low in July and August. Both Iwao's regression method and Taylor's power law found that nymphs and adults were aggregated, with nymphs being slightly more aggregated than adults. Cutting of bermudagrass reduced populations of nymphs and adults an average (± SEM) of 82.6 ± 7.9 and 71.6 ± 10.2%, respectively. These results demonstrate the potential of T. doddi to damage forage-type bermudagrass with damage being most likely to occur in June and during the fall. Timely cutting of forage may be a useful tool for managing T. doddi in bermudagrass." |
