Abstract
Uncertainties regarding the relationships between insect defoliation and yield loss limit existing management programs. Consequently, experiments were conducted over four years in multiple locations to better characterize soybean responses to defoliating insects. Results indicate that soybean yield reductions from insect defoliation primarily result from reduced light interception of defoliated plant canopies. Changes in leaf senescence were associated with defoliation and were identified as a compensatory mechanism. These results offer the potential for more accurate pest management guidelines and new approaches to managing defoliation through the development of defoliation-tolerant soybean varieties.
