Hypocotyls of vegetative V1 and V3 stage soybean, Glycine max (L.) Merrill were subjected to feeding by third, fourth, and fifth instars of the threecornered alfalfa hopper, Spissistilus festinus (Say). Significant differences in feeding injury, plant responses, fresh and dry root weights, and plant stage development occurred due to fourth instar feeding on V1 stage plants. Most soybean plants responded to partial and complete girdles by producing swelling and/or adventitious roots above the girdle.
