Population Fluctuations and Interplant Movements of Lygus Lineolaris1

Abstract
Adult Lygus Lineolaris (Palisot de Beauvois) overwinter near their autumn hosts and emerge soon after the spring snow melt. At first, tarnished plant bugs feed on a very few species of early growing weeds, but then move to sprouted alfalfa, where they complete 3 generations, the last 2 overlapping. Summer adults and nymphs disperse to many crops and weeds in flower.
