ESM 3 Effects of insecticide application on herbivore densities (individuals per leaf) of Walterianella inscripta and Eulepte gastralis on the focal host tree Tabebuia rosea. T. rosea was planted in monocultures (MON), in unprotected 3-species mixed stands in association with Anacardium excelsum and Cedrela odorata (MIX), and in insecticide-protected 3-species mixed stands (PRO). Effects were tested using binomial data (infested trees: herbivore densities > 0; non-infested trees: herbivore densities = 0) in a generalized linear mixed effect model as penalized quasi-likelihood approach with planting schemes as fixed factor and plot as a random factor, accounting for the nesting of planting schemes within plots. Results are given for (a) overall comparisons, and (b) multiple comparisons between individual planting schemes. Significant effects (P < 0.05) are shown in italics (after false discovery rate control of pairwise comparisons); numDF = numerator degrees of freedom, denDF = denominator degrees of freedom. Tree number per planting scheme: MON = 59, MIX = 60, PRO = 59
