dc.description.abstractIn herbivorous insects, the interaction between adult preference and progeny performance on specific host plants is modified by maternal feeding experience and host plant quality. Ultimately, changes in the strength of this interaction can affect insect population dynamics. In this study, we hypothesized that adult host plant preference influences progeny performance through a maternal feeding experience x host plant interaction, that is, the effect of adult feeding experience on progeny performance will depend on the host plant. Second, that decoupling of the preference-performance relationship due to host switching results in different population vital rates changing population dynamics. An increase in development time and a decrease in body size of individuals in the alternate host should decrease population growth. We tested these hypotheses using two lines of the tortoise beetle Chelymorpha varians Blanchard fed with two hosts (Convolvulus arvensis and Calystegia sepium). Maternal feeding experience treatments were crossed with host plant species, and the offspring's developing time and adult size were measured. The host plant influence on the beetle's population vital rates was tested using stage-structured matrix population models and life table response experiments. Host plant preference affected offspring body size through a host plant effect that contributed to adaptive life history responses only in the better quality host. C. varians' population growth was positive when fed with either host; comparatively, however, C. sepium had a negative effect on growth by reducing all transition probabilities of the life cycle stages of the beetle. Here, we show that individuals of C. varians prefer and perform differently on distinct hosts and that these patterns influence population vital rates in different ways. When beetles prefer the host plant where their progeny performs best, life history responses and life stage transitions lead to higher population growth; otherwise, growth rate decreases.
