Data analysis
The percentage mortality for the bioassays and percentage genotypic and
allelic frequencies for the dead and alive groups were computed in Excel
2016 spreadsheet (Microsoft). In addition, the odds ratio statistical
test was calculated on the medcalc website
(https://www.medcalc.org/calc/odds_ratio.php) to determine the strength
of association between genotypes and the ability to survive insecticide
exposure. Fisher exact test was used to assess the significance level
for the differences observed in the bioassay results, and results were
considered significant at P value less than 0.05.
