↵a LC

_{50}s were analyzed by a PROBIT model, and the 95% confidence intervals are given in parentheses.↵b The expected LC

_{50}s were calculated following Tabashnik's equation based on the additive effect of the two components.↵c The synergism factor was calculated by dividing the expected value by the observed LC

_{50}.
