Parallel and Nonparallel Patterns of Genetic Co-Differentiation: Evidence for Host Associated Differentiation Among Trophic Levels of the Oak Gall Wasp System
… life cycles are intimately related to their host plants can express host-associated differentiation (HAD) in the form of genetic divergence and/or RI isolation across alternative host plants. In this work, we ask if HAD cascades to higher trophic levels in parasitoids of an insect herbivore …

Investigation of pre- and post-zygotic reproductive barriers between two host-plant complex races of the parasitic wasp Cotesia congregata (Say) [Hymenoptera: Braconidae]
Investigations of host-associated differentiation of parasitoids have largely focused on the degree of molecular genetic differentiation, but a true test of species status must examine the mating patterns of differentiated populations to determine if they can interbreed in the wild and produce …

Experimental and Population Genetic Evidence of Host Race Formation in a Specialized Lycaenid Butterfly
Host-associated differentiation in phytophagous insects is an important mechanism of speciation. The current study investigates whether adaptation to different hosts drives population genetic divergence in the juniper hairstreak butterfly, Mitoura gryneus. Mitoura exhibit host plant fidelity, in …

Genetic differentiation of the parasitoid, Cotesia congregata (Say), based on host-plant complex
… have intimate relationships with their host species as well as the plant on which their host develops. Characteristics of both hosts and plants can affect parasitoid success in tri-trophic systems and thus, drive diversification. Genetic differentiation was estimated for Cotesia …
