Abstract
A method is described for partitioning normal plant fruit shedding losses from those caused by the pest Lygus hesperus Knight. The relationship between age of bug and its damaged rate per day degree was determined, and used to assess the impact of various lygus population levels on crop development and yield. A simulation model for lygus phenology and population dynamics is reported.Keywords
