摘要：

Sipha flava is an occasional pest of seedling Sorghum bicolor. Multiple regression equations used to calculate economic injury levels related S. flava number, plant spacing, and plant height to yield per plant. Economic injury levels ranged from 3 to 27%, 4 to 43%, and 11 to 100% infested plants for plants 3.5, 4.5 and 5.5 cm tall when control costs ranged from $5-25 ha-1 and crop values ranged from $250-500 ha-1. -from Authors
