Figures & data

Figure. 1. Aphids (mean ± standard error) after 20 days of infestation in plants of Solanum lycopersicum cv. Moneymaker (MM) and ABL 10-4, previously primed with caterpillars of Spodoptera littoralis (Spodoptera) or M. euphorbiae (Aphid) or with no previous infestation (Control). Capital letters indicate significant differences between the two genotypes; letters in lowercase indicate differences among treatments within a genotype, Generalized Linear Mixed Model p ≤ 0.001, n = 10.

Figure. 2. Population built-up (mean ± standard error) of M. euphorbiae on Solanum lycopersicum cv. CastleMart (CM, black line) and spr2. Aphid multiplication was monitored for 20 days. Different letters indicate significant differences in aphid multiplication between the compared genotypes according to a Generalized Mixed Linear Model with a Poisson error structure, p ≤ 0.001.
