Huanglongbing （HLB，or citrus greening） is the most destructive disease of citrus，which is associated with Candidatus Liberibacter asiaticus （Las）.Few management options are available，aside from preventive measures such as removing infected plants，planting disease-free seedlings，and managing the insect vector.In this study，we assessed the efficacy of thermotherapy against HLB under controlled greenhouse conditions.A total of 60 two-year-old，graft-infected Citrus reticulata Blanco plants were used.The plants were randomly divided into three groups （45°C，48°C，and untreated control），with five plants/replicate （rep） and four reps/treatment.The treated plants were placed in phytotrons for a 4-h treatment session，repeated once
