Generalized Linear Models (GLMs) with Gamma distribution tested with different behavioral traits as dependent variables.
Fig 1.
T. cruzi TcVI metacyclic trypomastigote (A) and epimastigote (B) loads in the excreta of T. rubrovaria and T. infestans. The number of infected and the total number of specimens analyzed for each condition are shown above each dotplot column. Different lowercase letters on the top indicate statistically significant differences (Kruskal-Wallis-test; A: p (a and b) < 0.05; Wilcoxon-Mann-Whitney W-tests B: p (a and b) = 0.002 and p (c and d) = 0.02). dpi = days post infection.

Generalized linear model for the presence of metacyclic trypomastigote forms of T. cruzi TcVI in the excreta of T. rubrovaria and T. infestans at different days post infection (dpi).
Fig 2.
Ingested blood volume and excretion status (0: Not excreted, 1: Excreted) of non-infected T. rubrovaria (NINF), and infected- T. rubrovaria (INF) and T. infestans (INF).
The number of samples analyzed for each condition is shown above each dotplot column. Different lowercase letters indicate statistically significant differences (Wilcoxon-Mann-Whitney W-test < 0.001).
Fig 3.
Feeding parameters of non-infected T. rubrovaria (NINF), and infected T. rubrovaria (INF) and T. infestans (INF)–ingested blood volume (A) and feeding efficiency (B). The number of samples analyzed for each condition is shown above each dotplot column. Different lowercase letters indicate statistically significant differences (Wilcoxon-Mann-Whitney W-test; A: p (ab) < 0.05, p (bc and ac) < 0.0001; B: p (ab) < 0.0001.

Model-averaged coefficients (± 95% CI) of the independent variables (white dots) and the intercepts (black dots) of generalized linear models.
Excretion time after a blood meal (A), excreta distance from the bite (B), ingested blood volume (C), feeding efficiency (D) and excretion efficiency (E). Dashed line shows y-axis = 0. Colon marks between variable names mean “interacting with”.
