Fig 4. Comparison of the COI-CS TpiR and COI-RS TpiC configuration frequencies that make up the discordant category described in Fig 3.

The mean frequency ± SD is listed for each category. Pair-wise comparisons between the means were calculated using single-tailed t-test with significant differences indicated by different lower-case letters. (A) Western Hemisphere collections. (B) Africa collections. The same collections were used as in Fig 3. All collections were from corn-strain preferred host plants.
