Residents’ contribution to Asian citrus psyllid and citrus greening management in Florida residential habitats

Abstract

Abstract The Asian citrus psyllid (ACP), Diaphorina citri Kuwayama (Hemiptera: Psyllidae), is the world’s most damaging citrus pest that transmits the bacteria that cause huanglongbing (HLB). In the fall of 2022, we investigated residents’ attitudes to ACP and HLB using online surveys over a 9-month period. The survey gathered information on citrus grown in backyards and on the detection of ACP and HLB, as well as the management strategies used (or ready to be implemented) to control them. We recorded 529 responses, 218 from areas where HLB is endemic (South and Central Florida) and 311 from areas where HLB and ACP are still rare (North Florida). In the HLB area, the number of citrus grown was significantly reduced, and residents were more active in controlling ACP and HLB. Most residents were able to identify an adult psyllid from a photo, but only 5% reported having seen it on their trees, in most cases in areas with high HLB incidence. The results also revealed residents’ interest in managing ACP and HLB, as well as their willingness to participate in the search for integrated solutions to tackle ACP and HLB in urban habitats. Interestingly, 76% of responders agreed to remove HLB trees from their backyard; this went up to 82% if compensation was offered. This study provides valuable insights for improving backyard Extension strategies tailored to the needs and willingness of residents to manage ACP and HLB.
