Abstract

<jats:title>Abstract</jats:title><jats:p>Individual variation in two species of host plants (thistle, <jats:italic>Cirsium kamtschaticum</jats:italic>, and blue cohosh, <jats:italic>Caulophyllum robustum</jats:italic>) of the herbivorous ladybird beetle <jats:italic>Epilachna pustulosa</jats:italic> was examined under laboratory conditions for their acceptability to adult beetles as a food resource, for adult preference and for larval performance. When clones of these plants were subjected to non‐choice tests using posthibernating female beetles, there was found to be significant intraspecific variation among clones in terms of their acceptability, but interspecific variation was not detected. Significant intraspecific as well as interspecific variation were frequently detected in the two host plants when clones of these plants were subjected to choice tests using posthibernating female beetles; the magnitude of interspecific plant variation for beetle preference is not necessarily larger than that of intraspecific plant variation. Individual variation across plant species with respect to beetle larval performance was also significant. A positive correlation between adult preference and larval performance is suggested across the two taxonomically remote host plant species, thistle and blue cohosh, although this needs further investigation.</jats:p>
