Spatial Distribution and Development of Sequential Sampling Plans for Diaphorina citri Kuwayama (Hemiptera: Liviidae)

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