註釋Grain sorghum is an increasingly important food crop. Approximately 30 million tons are produced annually. The sorghum midge (Contarinia sorghicola) destroys up to 90 percent of a given sorghum crop. Since the use of resistant sorghums has received little attention, previous gains in this area of control have been meager. This study was designed to evaluate the preference mechanism of resistance in 10 selected lines of grain sorghum, which varied in degree of resistance. In addition, data on overwintering midges and parasitism were collected.
