Appendix E. Female Papilio machaon aliaska oviposition preferences for polar Cnidium cnidiifolium extract (Cc) compared to preferences for Cnidium cnidiifolium extract combined with either polar Artemisia frigida extract (Cc+Af) or A. frigida fractions (Cc+AfF1 and Cc+AfF2). C. cnidiifolium is the ancestral host plant of P. m. aliaska. A. frigida is not a P. m. aliaska host plant. Tukey-Kramer adjusted t values are reported for differences in the least squares means between treatments.
