Empoasca kraemeri
bean leafhopper, potato leafhopper (Latin America)
Empoasca kraemeri is a leafhopper species in the family Cicadellidae, native to the Americas and a significant agricultural pest of common bean (Phaseolus vulgaris) in Latin America. It is closely related to the North American potato leafhopper E. fabae, with which it shares similar feeding habits and damage symptoms. The species exhibits phloem-feeding behavior that causes characteristic "hopperburn" injury to host plants, and shows differential cultivar preferences in bean crops. Peak nymph populations occur approximately 42-49 days after host plant germination, with highest presence during pod filling to ripening stages.
