Models of sympatric speciation for phytophagous insects posit a central role for host plant-associated mating as a premating isolating mechanism in lieu of geographic barriers to gene flow. Here, by means of three mark-and-recapture studies, we confirm that host fidelity (i.e., the tendency of an insect to reproduce on the same host species that it used in earlier life-history stages) restricts gene flow between sympatric apple- and hawthorn-infesting races of Rhagoletis pomonella (Diptera… Expand
Divergent host plant specialization as the critical driving force in speciation between populations of a phytophagous ladybird beetle
TLDR
This work tested isolating barriers between host races of a phytophagous ladybird beetle, Henosepilachna diekei, and found significant genetic divergence between the host races, and extremely divergent host preference and host performance. Expand
Selective maintenance of allozyme differences among sympatric host races of the apple maggot fly.
TLDR
The findings confirm that postzygotic reproductive isolation can evolve as a pleiotropic consequence of host-associated adaptation, a central tenet of nonallopatric speciation and suggest that one reason for the paucity of reported fitness trade-offs is a failure to consider adequately costs associated with coordinating an insect's life cycle with the phenology of its host plant.

HABITAT AVOIDANCE: OVERLOOKING AN IMPORTANT ASPECT OF HOST-SPECIFIC MATING AND SYMPATRIC SPECIATION?
TLDR
Results from field trials indicate that in addition to preferring the odor of their natal fruit, apple and hawthorn flies, and their undescribed sister species infesting flowering dogwood, also avoid the odors of nonnatal fruit. Expand

TLDR
H hierarchical estimates of population structure based on Fst suggest that gene exchange between closely adjacent aphid populations on the two hosts is highly restricted relative to that among fields of the same host plant. Expand
HABITAT AVOIDANCE: OVERLOOKING AN IMPORTANT ASPECT OF HOST‐SPECIFIC MATING AND SYMPATRIC SPECIATION?
TLDR
Results from field trials indicate that in addition to preferring the odor of their natal fruit, apple and hawthorn flies, and their undescribed sister species infesting flowering dogwood, also avoid the odors of nonnatal fruit. Expand
Reproductive barriers between two sympatric beetle species specialized on different host plants
TLDR
Both ecological and intrinsic factors may contribute to speciation between these species, and the genetic basis of preference and performance was at least partially independent, and several loci coded for preference, which limits the possibility of sympatric speciation. Expand
Host Fidelity of the Pollinator Guilds of Silene dioica and Silene latifolia: Possible Consequences for Sympatric Host Race Differentiation of a Vectored Plant Disease
TLDR
It is speculated that the observed sympatric host‐specific differentiation is due to a combination of factors, including vector behavior and host spatial and temporal structure. Expand
Divergent host plant preference causes assortative mating between sympatric host races of the ladybird beetle, Henosepilachna diekei
TLDR
The results suggest that fidelity to the different host plants yields directly almost complete reproductive isolation between the host races by limiting the habitat on the respective host plant. Expand
Natural selection and sympatric divergence in the apple maggot Rhagoletis pomonella
TLDR
A gene–environment interaction (fitness trade-off) that is related to host phenology and that genetically differentiates the races is documented. Expand

TLDR
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.
