Table 1.

The effect of plant and herbivore inbreeding on herbivore A. asclepiadis oviposition preference and herbivore egg survival on its host plant V. hirundinaria. ‘Lost’ refers to parasitized, detached and perforated eggs combined. Italicized values denote p-values of <0.05. d.f. = numerator, denominator d.f. for F-values for oviposition.
