“…Moreover, D. citri that acquire Las initiates the flight sooner than Las-negative D. citri (Martini et al 2015). The pathogeninduced increases in flight initiation and a short-distance dispersal by the vector probably favor multiple inoculations of the plant host at different locations, whereas an increase in long-distance dispersal may benefit the spread of the pathogen to distant areas (Martini et al 2015;Stelinski 2019). Las does not affect the duration and speed of the long flights of D. citri.…”

Interactions between insects and plant pathogens have been more enthusiastically studied in the recent decade, especially those relationships which takes the insects as vectors. The spectrum of these interactions ranges from mutualistic to pathogenic. The length of the co-evolutionary process will determine whether a microorganism shares a friend or a foe relationship with its host, and a friendship connection is frequently observed if the coexistence is longer. This review updates knowledge about the morphological, physiological and genetic mechanisms that drive the interaction between 'Candidatus Liberibacter asiaticus' (Las) and its vector, the Asian citrus psyllid, Diaphorina citri. Las is the predominant causal agent of citrus huanglongbing (HLB) disease, the major constrain to citrus production worldwide. This bacterium is transmitted by D. citri, in a propagative-circulative manner during its feeding from plant host. Understanding of the interactions among vector, plant pathogen and host plant are important for the management of this vector-borne disease complex.

“…An effective, large-scale treatment for older citrus trees infected with HLB has not been found yet (Singerman and Useche, 2016). Therefore, efforts are directed toward addressing the health of young citrus trees in nurseries (Rumble et al, 2016;Ruth et al, 2017;Stelinski, 2019). To ensure that newer generations of citrus saplings do not become infected with HLB, two main methods are being developed.…”

mal growth environment, which causes reproduction to occur at a fast and steady rate. As the disease progresses, the bacteria slowly obstruct the systemic phloem and block the sugar transport to the roots, ultimately killing the tree within a decade of initial symptom development (Bové, 2006). Unfortunately, there is still a lack of treatment options that are technically feasible, sustainable, and environmentally safe, since C. Las cannot be cultured, making lab work extremely challenging (Grafton-Cardwell et al., 2013). HLB has spread to nearly all major citrus-producing regions around the world (Chen et al., 2018). In Florida alone, the estimated damage over the last five years amounts to over $1 billion per year and around 5000 jobs are lost yearly (Li et al., 2020).Younger seedlings are extremely susceptible to C. Las. Once they are infected, their health slowly declines, reducing the productivity and quality of the fruit. HLB-affected fruit are lopsided, bitter, hard, and green when ripe (Burrow and Dewdney, 2019). All infected trees will eventually succumb to HLB unless an effective treatment methodology is developed.Citrus growers are currently using bactericides such as streptomycin and oxytetracycline as an attempt to kill the bacteria in the tree, but they have provided no significant improvements (Li et al., 2020). Growers currently utilize two main therapeutic application methods: soil drench and foliar application (Eveland and Brown, 2019). Although soil drench, where treatments are added to the base of the plant

“…In China and Brazil, the number of sprays has a range from 18 [21] up to one/week/all year around (52 in total) [22]. This approach is economically unsustainable [14,23], environmentally unviable, socially questionable, and largely unsuccessful [14,20,23,24] and it is clear that new tools need to be developed and incorporated into the management of ACP [14].…”

Vector control in huanglongbing management has been conducted on a calendar basis resulting in high production costs. We addressed this issue and proposed a sequential sampling plan to support decision making for intervention against Diaphorina citri Kuwayama, which is involved in the transmission of the bacteria Candidatus Liberibacter asiaticus, associated with such lethal disease. We analyzed 3,264,660 records from samples gathered from the Mexican trapping program for the monitoring of D. citri; it included weekly inspection of 86,004 yellow sticky traps distributed in the country. Spatial distribution of the insect, estimation of a common k (kc), and sequential sampling plans based on Sequential Probability Ratio Test (SPRT) were determined. Taylor’s power law coefficients were ≥1 indicating aggregation in the spatial distribution of the insect. Common k ranged from 0.0183 to 0.2253 and varied independently of geographic zone or citrus species. We obtained 18 sequential sampling plans, one for each state. In the Average Sample Number (ASN) function, the minimal number of samples to make a decision ranged from 17 to 65. In the Operational Characteristic (OC) function, probabilities for a correct intervention at the threshold of 0.2 D. citri adults/trap in most cases were above 80%. In a field evaluation, the application of sampling plans yielded savings obtained by reduction in the number of interventions for insect control.
