Table 3 Activity of diflubenzuron to Bti-selected Ae. aegypti larvae

From: Long-term exposure of Aedes aegypti to Bacillus thuringiensis svar. israelensis did not involve altered susceptibility to this microbial larvicide or to other control agents

Samplea No. of larvae EIC50 (95% CI)b RRc EIC90 (95% CI)b RRc
Rocke 1680 0.774 (0.662–0.903) 1.0 1.422 (1.226–1.940) 1.0

  1. aRockefeller (Rocke) reference strain and the RecBti selected strain (generation F30)
  2. bEmergence inhibitory concentrations (μg/l) for 50% and 90% of adults from third-instar larvae exposed for 30 days (mean and 95% confidence intervals, CI)
  3. cResistance ratio between the EIC for the test strain and that for the reference strain
