Lygus hesperus
Western Tarnished Plant Bug
Lygus hesperus is a significant agricultural pest in western North America, causing extensive damage to cotton, strawberries, alfalfa seed, and other crops. In California alone, annual losses exceed $30 million in cotton and $40 million in strawberries. Adults overwinter in reproductive diapause triggered by short day lengths, resuming activity when conditions improve. The species has been the subject of extensive research on sampling methods, biological control, and insecticide resistance.
