Fig 1.
Percentage of mortality of S. exigua larvae that fed on (necrophagy) or had physical contact with infected and non-infected cadavers (n = 82).
Fig 2.
Number of feeding events (+ SE) of S. exigua larvae on spinach discs with different treatments.
a) disc contaminated with virus-infected cadaver vs water (control) (n = 45); b) disc contaminated with infected cadaver vs non-infected cadaver (n = 45). Different letters indicate significant differences between groups (t test, p <0.05).
Fig 3.
Distribution of live larvae on plant when they were eating, walking and resting, as well as the position of the cadavers (infected and uninfected), (n = 23).
a) Height on plant, the scale is presented in terms of relative height with respect to the total height of each plant. b) Distance from stem (cm). Different letters indicate significant differences (ANOVA, p <0.05).
Fig 4.
Mean distance between healthy larvae and infected or non-infected cadavers.
a) Hourly means of observations performed over a 48 h period on each larva (n = 22 larvae). Points labeled with numerical values indicate number of acts of necrophagy observed at each time point (values shown in blue refer to necrophagy on non-infected cadavers, values in red refer to necrophagy on infected cadavers); b) Mean percentage of observations in which the experimental insect was closer to the infected (red column) or non-infected (blue column) cadaver. Vertical bars indicate SE.
