Table 2. Insecticidal activity of six eco-friendly organic materials (EFAM) and one chemical insecticide (fenitrothion EC) against R. mikado at 1, 3, 7 days after treatment (DAT) in laboratory conditions (25±2°C, 70±10% RH, 16L:8D) with statistics for one-way ANOVA. Control was a group of water-sprayed instead of insecticidal materials. Different letters indicate significant difference of R. mikado mortality based on Tukey’s HSD test.
