Abstract
Pollinating bags were used to cover 200 newly emerged grain sorghum heads. Bags were removed from 10 plants daily for 10 consecutive days in a manner that exposed each group to midge oviposition for a 24-hour period. Harvested heads were kept in emergence cages. Life cycle of the midge was calculated on the elapse of time between head exposure and adult midge emergence, which ranged from 12 to 21 days. Four spray schedules were followed to determine the effectiveness of the application of each of 12 insecticides for control of the midge. Application of insecticides within a 4-day period after about 90% of the heads emerged from the boot resulted in an increase in sorghum grain yields.
