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.
