Abstract The interactions between plant‐eating insects and their hosts have shaped both the insects and the plants, driving evolution of plant defenses and insect specialization. The leaf beetle Trirhabda eriodictyonis (Chrysomelidae) lives on two shrubs with differing defenses: Eriodictyon crassifolium has hairy leaves, whereas E. trichocalyx has resinous leaves. We tested whether these beetles have differentiated onto the two host plants, and if not, whether the beetles prefer the better host…

Do differences in life‐history traits and the timing of peak mating activity between host‐associated populations of Chilo suppressalis have a genetic basis?

Although some life‐history traits of host‐associated populations of C. suppressalis are influenced by the host plant larvae are raised on, time of peak mating activity is not, which indicates that the mechanism responsible for host race formation in this species is still unclear.

Experimental evidence of host race formation in Mitoura butterflies (Lepidoptera: Lycaenidae)

Investigating host shifts and variation in traits potentially involved in the evolution of reproductive isolation among populations of the juniper hairstreak butterfly, Mitoura gryneus provides strong support for the hypothesis of ongoing host race formation in these butterflies.

It is clear that trichomes play a role in plant defense, especially with regard to phytophagous insects, and in numerous species there is a negative correlation between trichome density and insect feeding and oviposition responses, and the nutrition of larvae.

The objective of this paper is to point out how the biological attributes of these flies may have permitted new forms to arise rapidly in the absence of geographical barriers to gene flow.

A meta-analysis of preference-performance relationships in phytophagous insects.

Meta-analysis is used to assess the balance of evidence for and against the preference-performance hypothesis (PPH), and to evaluate the role of individual factors proposed to influence host selection by female insects.

Adaptive patterns of host-plant selection by phytophagous insects

A challenge for the future is to assess the adaptive value of particular mechanisms of host-selection, and to relate these to the predictions made in simple adaptive models.

The role of leaf resin in the interaction between Eriodictyon californicum (Hydrophyllaceae) and its herbivore, Trirhabda diducta (Chrysomelidae)

The results show that the Eriodictyon leaf resin affects Trirhabda larvae and adults similarly, having no significant effect on growth rates or on nutrient utilization at up to 5X the resin levels normally encountered by larvae in the field.

The results of the bioassays demonstrated that male and female CHC did not elicit sex discriminative male behavior, but induced mating by males regardless of the sex of the partner.

This work provides verifiable criteria to distinguish host races from other biotypes, and discusses applications of an understanding of host races in conservation and in managing adaptation by pests to control strategies, including those involving biological control or transgenic parasite-resistant plants.
