Beyond Predation: The Zoophytophagous Predator Macrolophus pygmaeus Induces Tomato Resistance against Spider Mites
Fig 2
Local plant-mediated effects of Macrolophus pygmaeus on Tetranychus urticae performance.
M. pygmaeus females were enclosed in clip cages on the abaxial side of the second oldest leaf (L2) at a defined leaflet (Lf2) for 4 days before 10 young T. urticae females were kept on the same leaflet without access to the area pre-exposed to M. pygmaeus (inset). (A) Number of eggs per plant and (B) proportion of alive T. urticae females on the same leaflet that was previously exposed to 1 (38 plants) or 5 (36 plants) female predators (dark bars) or the corresponding leaflets of (37) control plants (white bars) (mean +/- S.E., plants, in three blocks). Significant differences between exposed plants and control plants are indicated by different letters by Tukey contrasts following a GLMM.
