“…Regarding D. citri spatial distribution, most psyllids were found in the first rows of citrus (Fig. 3) regardless of the treatment and assessment period, reinforcing psyllid preference for trees located in the border of the orchards 10,25,26 . Psyllids released in front of the trap crop plots did not disperse further than the first row of citrus, whereas individuals released in front of control plots were able to cross the first row and were present in almost all rows.…”

Novel, suitable and sustainable alternative control tactics that have the potential to reduce migration of Diaphorina citri into commercial citrus orchards are essential to improve management of huanglongbing (HLB). In this study, the effect of orange jasmine (Murraya paniculata) as a border trap crop on psyllid settlement and dispersal was assessed in citrus orchards. Furthermore, volatile emission profiles and relative attractiveness of both orange jasmine and sweet orange (Citrus × aurantium L., syn. Citrus sinensis (L.) Osbeck) nursery flushes to D. citri were investigated. In newly established citrus orchards, the trap crop reduced the capture of psyllids in yellow sticky traps and the number of psyllids that settled on citrus trees compared to fallow mowed grass fields by 40% and 83%, respectively. Psyllids were attracted and killed by thiamethoxam-treated orange jasmine suggesting that the trap crop could act as a ‘sink’ for D. citri. Additionally, the presence of the trap crop reduced HLB incidence by 43%. Olfactometer experiments showed that orange jasmine plays an attractive role on psyllid behavior and that this attractiveness may be associated with differences in the volatile profiles emitted by orange jasmine in comparison with sweet orange. Results indicated that insecticide-treated M. paniculata may act as a trap crop to attract and kill D. citri before they settled on the edges of citrus orchards, which significantly contributes to the reduction of HLB primary spread.

“…Hence, the best target locations for monitoring the migrant psyllid population have been established, with the aim of determining the critical times for insecticide applications and preventing further infections (Bassanezi et al 2010). For D. citri monitoring, yellow sticky cards are recommended due to their greater effectiveness than other methods, e.g., tap and visual inspection (Miranda et al 2018).…”

“…Similar efficacy to chemical insecticides in terms of D. citri adult control was observed under field conditions (Ausique et al 2017). Preventive applications of processed kaolin interfered negatively in the ability of D. citri to find the host plant and in the proportion of individuals that were able to reach the citrus phloem, suggesting its potential to reduce HLB primary infection (Miranda et al 2018).…”

Huanglongbing (HLB) has been a serious threat to the citrus industry worldwide. After its first report in São Paulo State, the main citrus production area in Brazil, the disease spread to the States of Minas Gerais, Paraná and Mato Grosso do Sul. Attempts to cure plants or remiss disease symptoms and damages have been evaluated and showed to be inefficient and nonviable. The development of resistant or tolerant varieties to the bacteria or its insect vector, the Asian citrus psyllid Diaphorina citri, is still a long term challenge. Earlier HLB management has been based on preventive measures such as planting of healthy nursery trees, elimination of diseased trees, and vector control. Supported by both research data and citrus grower experiences, HLB management in São Paulo and Triângulo/Sudoeste Mineiro citrus belt has been improved from measures individually applied only into the orchards to regional disease management, including differentiated psyllid control in the orchards based on tree location and shoot flushing, area-wide coordinated control of psyllids, and removal of inoculum sources in noncommercial properties in the vicinity of commercial orchards. In addition, the negative impact of HLB on orchard production and longevity has been reduced with wide adoption of better cultural practices such as high-density planting, irrigation, and adequate nutrition. Unlike in other countries where HLB reached epidemic levels, the management of HLB in São Paulo and Triângulo/Sudoeste Mineiro citrus belt has been considered a success case and has ensured the maintenance of citrus production and competitiveness of the Brazilian citrus industry while new, more durable, and sustainable measures are not yet available.

“…In view of these considerations, it is essential to monitor and control D. citri populations not only in commercial orchards, but also in surrounding areas that may serve as foci of infected individuals. Yellow sticky traps are considered the most efficient method for D. citri detection in citrus orchards (Miranda et al 2017); a slow-release attractant based on acetic acid can be applied to the trap to increase its efficiency (Zanardi et al 2018). Early detection is essential not only to control immigrating adults but also to prevent nymphs from developing on citrus and other host plants of HLB-associated liberibacters, since the likelihood of transmission is higher after the nymphs acquire the pathogen (Inoue et al 2009;Ammar et al 2016;George et al 2018).…”

“…Based on this information, psyllid monitoring and control should be intensified at the orchard borders and in seasons when psyllids show higher flight activity. In addition, trap-plant barriers, particle-film applications, mulching, and other cultural practices are under investigation as blocking methods to reduce psyllid entry through orchard borders (Croxton and Stansly 2014;Tomaseto et al 2016;Miranda et al 2018).…”

Citrus huanglongbing (HLB) represents a major threat to citriculture due to its rapid spread, difficulty of control, severe yield losses, and substantial increases in production costs in HLB-affected orchards. Successful management depends on detailed knowledge of the epidemiology of this disease, which is associated with phloem-limited bacteria of the genus Candidatus Liberibacter that are transmitted by phloem sap-feeding insects known as psyllids (Hemiptera: Psylloidea). Candidatus L. asiaticus (CLas) and the Asian citrus psyllid Diaphorina citri Kuwayama are the major etiological agent and vector, respectively, in the Americas and Asia. This review provides up-to-date information on the relationships of psyllid vectors with Ca. Liberibacter spp. associated with HLB, with emphasis on D. citri and CLas. Knowledge of the transmission mechanisms of these bacteria, as well as aspects of the biology, ecology, and behavior of the vector in relation to the environment, is essential to gain understanding of the HLB epidemics. Such knowledge provides a basis for developing innovative control methods and establishing sustainable management strategies for HLB.
