Chromosomal regions of sorghum, Sorghum bicolor (L.) Moench, conferring resistance to greenbug, Schizaphis graminum (Rondani), biotypes C, E, I, and K from four resistance sources were evaluated by restriction fragment-length polymorphism (RFLP) anal

Resistance of sorghum, Sorghum bicolor (L.) Moench, to sorghum midge, Stenodiplosis sorghicola (Coquillett), has not been well understood. In this study, possible causes of resistance were examined by comparing time of oviposition with times spikelet

Future advances in wheat, Triticum aestivum L., and sorghum, Sorghum bicolor (L.) Moench, resistance to greenbug, Schizaphis graminum (Rondani), will likely come from introduction of resistance transgenes into high-performance cultivars. First-genera

Seedlings of 462 sorghum lines were screened to identify resistance to the sugarcane aphid, Melanaphis sacchari (Zehntner). About 7% of the lines exhibited resistance in the seedling stage in greenhouse trials. In an advanced screening experiment, 12

Resistance mechanisms and the effect of temperature and photoperiod on them were assessed for greenbug, Schizaphis graminum (Rondani), biotype C on ‘Tx2737’ and ‘Tx2783’ sorghums and for biotype E on ‘Tx2783’ at 21, 26, and 30°C at photo

A total of 39,687 assessments of abundance of ovipositing sorghum midge, Contarinia sorghicola (Coquillett), and sorghum, Sorghum bicolor (L.) Moench, spikelets in flower were used to evaluate, refine, and validate a sorghum midge population dynamics

The effectiveness of sorghum resistance to sorghum midge, Contarinia Sorghicola (Coquillett), was improved in mixed plantings of resistant and susceptible sorghum, Sorghum bicolor (L.) Moench, hybrids in 1989 and 1992. Mixed plantings drew sorghum mi

Field studies were conducted to evaluate methods for estimating field abundance of corn earworm, Helicoverpa zea (Boddie), sorghum webworm, Celama sorghiella (Riley), rice stink bug, Oebalus pugnax (F.), and sorghum midge, Contarinia sorghicola (Coqu
