The mortality of the larvae tested 3 days after the release was observed, and from the observation results, the mortality rate was calculated by Equation 6) and the corrected mortality rate was calculated by Equation 7). The test was repeated twice. The average value is shown in Table 12.

  Formula 6); death rate (%) = (number of test insects−number of surviving insects) / number of test insects × 100

  Formula 7); corrected mortality rate (%) = {(treated area mortality rate−untreated area mortality ratio) / (100−untreated area mortality ratio)} × 100
