Table 1. Corrected mortality (%), mean survival time and LT50 (days) of L. decemlineata immature stages treated by suspensions of 5×107 blastospores/ml of I. fumosorosea CCM 8367.
Treated Stage | Mortalitya | Mean survival time ± SEb | LT50 (95% CI) | Nc | Wilcoxon testd |
---|---|---|---|---|---|
Last-instar larva | 89.2 | 3.80±0.15 | 3.5 (3.0–4.0) | 40 | a |
Pre-pupa | 82.9 | 4.38±0.19 | 4.0 (4.0–5.0) | 40 | ab |
Pupa | 77.5 | 4.80±0.27 | 5.0 (5.0–6.0) | 40 | b |
a Percent of dead individuals at the end of experiment corrected for mortality in control using Abbott equation [44].
b The mean survival time and its standard error were underestimated because the largest observation was censored.
c Total number of individuals in bioassay.
d Identical lowercase letters within a column indicates no significant differences at α = 0.05 adjusted according to the Holm-Bonferroni method for multiple comparisons [46].
