Prioritization of absent quarantine pests in Brazil through the Analytical Hierarchy Process.

Introducing an Absent Quarantine Pest (AQP) can cause severe economic, social and environmental impacts, generating food insecurity. The Analytical Hierarchy Process (AHP) method is an excellent tool for prioritizing APQs, allowing countries to better prepare against these threats. This study aimed to determine which AQPs should be prioritized in Brazil. For this, 20 AQPs were selected from the Brazilian official list. The selection was based on pests intercepted by Brazil between 2015 and 2018 and by countries of the European and Mediterranean Plant Protection Organization, in the international movement of plants. It can be concluded that out of the 20 AQPs studied, 17 are the priority and that the AHP method is effective for this purpose. Other countries from different continents can use this methodology to prioritize PQAs and thus create strategic plans to prevent entry into their territories and economic, social, and environmental impacts.

Spatial distribution of Ceratitis capitata in guava orchards and influences from orchard management.

The objectives of this research were: (i) to Estimate the quantitative occurrence of Ceratitis capitata captured in McPhail traps in cultivating guava; (ii) to investigate the spatial distribution patterns of C. capitata in guava orchards; (iii) to compare the index of the FTD (fruit fly/trap/day) to the type of spatial distribution of C. capitata with the Negative Binomial to set the best time for control of the population in the context of Integrated Pest Management; (iv) Verify the influence of the pruning, spraying, and mowing on the distributions of medfly in guava. Was used 30 McPhail traps installed in three commercial orchards of guava. The spatial distribution was evaluated by the regression model with the Taylor power method, from the log of variance to the log of the mean number of individuals. Ceratitis capitata has aggregated distribution behavior. The potential risk of economic damage is associated with aggregate distribution behavior. The beginning of this distribution indicates the most appropriate time for using control techniques.
