Herbivorous insects often control their offspring's fate through
oviposition and provisioning choices. These choices may be in-
fluenced by a diversity of plant secondary compounds that could
affect both adult and offspring performance (Mayhew, 2001).
Plant secondary compounds are often thought to increase plant
fitness in the presence of herbivores by reducing herbivore feed-
ing rates (Fritz & Simms, 1992). However, not all secondary
compounds deter insects and some even increase herbivore sur-
vival and reproduction (Vrieling et al., 1991; Fritz & Simms,
1992; Cole, 1997; Awmack & Leather, 2002), especially for
phytophagous insects that specialize on plants with particular
secondary compounds (Ehrlich & Raven, 1964). Theoretically,
adult herbivore preference should evolve to optimize offspring
performance, especially when there is no parental care and low
