Project description:In Hawaii, a rapidly-evolving mutation in the field cricket Teleogryllus oceanicus silences males by interfering with the development of sound-producing structures on their forewings. The mutation is called flatwing (fw), and it persists because of natural selection imposed by an acoustically-orienting parasitoid. We examined gene expression differences between wild-type and mutant crickets, focusing on juvenile wing buds. We profiled mRNA expression levels using RNA-seq, and characterized the wing bud proteome using quantitative mass spectrometry. Accessing protein expression profiles under the same experimental conditions enabled us to test correspondence between the two ‘omic levels.

Project description:Among the parasites of insects, endoparasitoids impose a costly challenge to host defenses because they use their host’s body for the development and maturation of their eggs or larvae, and ultimately kill the host. Tachinid flies are highly specialized acoustically-orienting parasitoids that release first instar mobile larvae which burrow into the host’s body to feed. We investigated the possibility that Teleogryllus oceanicus field crickets employ post-infestation strategies to maximize survival when infested with the larvae of the parasitoid fly Ormia ochracea. Using crickets from the Hawaiian island of Kauai, where the parasitoid is present, and crickets from the Cook Islands (Mangaia), where the parasitoid is absent, we evaluated fitness consequences of infestation by comparing feeding behavior, reproductive capacity, and survival of males experimentally infested with O. ochracea larvae. We also evaluated genetic mechanisms underlying host responses by comparing gene expression in crickets infested with fly larvae for different lengths of time with that of uninfested control crickets. We observe some differences in fitness (spermatophore production) and survival (total survival time post-infestation) between populations. However, for both traits significant population effects 1) were not associated with the slope of the response to different numbers of larvae and 2) only emerged from models containing body condition at one but not both time points evaluated. Gene expression patterns also revealed population differences in response to infestation. We did not find evidence for consistent differences in genes associated with immunity or stress response. Taken together, these results suggest that coevolution with the fly does not strongly select for either post-infestation resistance or tolerance of parasitoid larvae in male crickets.
