Meta-Analysis Raw Data

This PRIVATE area of the Nzitrap.com web site can only be accessed from the link on the Research Home page. It contains the raw data and analyses supporting a meta-analysis of Nzi trap performance for standardized experiments conducted with numerous collaborators, mostly from the 1990's. This is still a "WORK IN PROGRESS", but so far all of the comparative, and standardized experimental data from Mihok and collaborators have been summarized.

 Fabric Resources Meta--Analysis

 

bulletEach experiment is summarized in a WORD file.

Each file is a straightforward guide that includes ANOVA output generated by SYSTAT. Some of these files are brief as I have not taken the time to annotate everything in detail. The file name corresponds to the experimental code in the EXCEL reference NziTrials. Raw data for three recent experiments are consolidated in another small file: Recent Trials. Original data are missing for one experiment (BERNDE02).
 

bulletThe RAW data and detailed statistics are in an EXCEL file.

Each file contains a RAW worksheet for one experiment extracted from the master reference and crosschecked against original records. Log (X+1) transformed catch data are calculated in a LOG worksheet via the macro CTRL+C using formulas in the TEMP worksheet. Note that you will get a macro warning when you open these EXCEL files.

The LOG file was imported into SYSTAT for statistical calculations. SYSTAT was used to provide the Mean Square Error, Degrees of Freedom and sample size information required to estimate response ratios. The CATCHES worksheet provides a quick point of reference for the species captured. These files may contain short notes on species or missing values but in general follow the same format throughout. Relevant response ratio data were transferred to the master database of Response Ratios using the worksheet DBASE.
 
bulletThe reflectance (cloth) and transmittance (netting) data are in a second EXCEL file.

These files were created several years ago and are a quick source of information for the fabrics used to make traps. They should contain the same information as the master fabric references in EXCEL and in ACCESS. I have not taken the time to confirm this.
 
bulletThe SYSTAT data file created from the log (X+1) worksheet in the EXCEL data file is provided along with a text file of the SYSTAT commands used to generate the ANOVAS.

These files can be used with SYSTAT (or any similar statistical package with minor adjustments) to analyze the data with a simple modification of the directory references at the beginning of the command file. Note that these files may contain commands specific to idiosyncrasies of each experiment. Note that the RAW and LOG worksheets in the original EXCEL file contain the same header row. Hence, to analyze untransformed data, simply import the RAW worksheet into SYSTAT and re-analzye the data with the command file.
 
bulletCodes for other standard biting fly traps should be self-evident. Some files will contain additional experimental Nzi traps with codes that are meaningful only to me until this work is formally published.

All key trials include a NZI-COT standard trap (phthalogen blue cotton, Ethiopian or Kenyan fabric), and most also include a NZI-POL standard trap (Vestergaard Frandsen's original "pongee 2" pure blue 100% polyester from the mid-1990's). The original goal of this research was to test Nzi traps made from blue fabrics #105 and #101 in 3-times replicated 3 x 3 Latin squares relative to a "local" standard trap. Fabrics #105 and #101 are simply large lots of the equivalent fabrics #60 and #65 that did well when tested in Expt 23 of Mihok (2002).
