Bolls with age determined by heat unit accumulation after anthesis were subjected to adult tarnished plant bug attack. Studies were conducted for two years, 1997 and 1998. Injury measurements were made on bolls to determine influence of boll age on susceptibility to tarnished plant bug injury. The results indicated that bolls that have accumulated 250 HU are relatively safe from tarnished plant bug injury. |
