Resampling Validation of Sample Plans (RVSP)

    Sets of tools for sample plan evaluation originally released in 1997, these Monte Carlo simulations can be used to evaluate sampling models during the developmental phase; however, they may not be adequate for testing model validity and performance under field conditions. This is primarily due to the assumption of an underlying statistical distribution (e.g., negative-binomial, normal) which may not adequately represent the actual distributions of insects in all instances. Here we present a method in which actual field data is resampled to evaluate sample plan performance. We originally developed DOS-based computer software for this purpose.

    Data from: Retrospective Analysis of a Classical Biological Control Program

      Field-based, partial life table data for immature stages of *Bemisia tabaci* on cotton in Maricopa, Arizona, USA where data provide the marginal, stage-specific rates of mortality for eggs, and 1st, 2nd, 3rd, and 4th instar nymphs, and life table data that were used to provide parameters for population matrix models. The model can be used to estimate overall population growth rate and can also be analyzed to determine which life stages contribute the most to changes in growth rates.

      Weevils of North America (WoNA)

        The Weevils of North America (WoNA) (http://symbiota4.acis.ufl.edu/scan/portal/checklists/checklist.php?cl=1) is an emerging resource for occurrence information, habitus photographs, legacy descriptions, and interactive identification keys for the almost 400 genera and 3300 species of weevils (Coleoptera: Curculionoidea) in North America.
