Abstract Differences in interspecific mating traits, such as male sexual signals and female preferences, often evolve quickly initial barriers to gene flow between nascent lineages, they may also strengthen during secondary contact via reinforcement. However, it is an open question whether loci contributing intraspecific variation traits are co-opted the formation strengthening of species. To test this, we used a population genomics approach natural populations Australian cricket sister species that overlap zone: Teleogryllus oceanicus commodus. First, identified associated with T. signals: advertisement song cuticular hydrocarbon (CHC) pheromones. We then separately candidate barrier Genes showing elevated allelic divergence were enriched for neurological functions, indicating potential behavioral rewiring. Only two CHC-associated genes overlapped these loci, CHC showed signatures being under strong selective constraints In contrast, 10 song-associated high genetic differentiation commodus oceanicus, 2 had genomic divergence. The overall lack shared intra vs. comparisons trait consistent limited co-option architecture establishment maintenance reproductive isolation.

ABSTRACT Farmed insects have gained attention as an alternative, sustainable source of protein with a lower carbon footprint than traditional livestock. We present high‐quality reference genome for one the most commonly farmed insects, banded cricket Gryllodes sigillatus . In addition to its agricultural importance, G. is also model in behavioural and evolutionary ecology research on reproduction mating systems. report comparative genomic analyses that clarify cricket's history, identify gene family expansions contractions unique this lineage, associate these agriculturally important traits, targets genome‐assisted breeding efforts. The assembly plus accompanying serve foundational resources both applied basic insect farming biology, enabling researchers pinpoint trait‐associated genetic variants, unravel functional pathways governing those phenotypes, accelerate selective efforts increase efficacy large‐scale operations.

Abstract Behavioural flexibility might help animals cope with costs of genetic variants under selection, promoting adaptation. However, it has proven challenging to experimentally link behavioural the predicted compensation population‐level fitness. We tested this prediction using field cricket Teleogryllus oceanicus . In Hawaiian populations, a mutation silences males and protects against eavesdropping parasitoids. To examine how loss critical acoustic communication signal impacts offspring production mate location, we developed high‐resolution, individual‐based tracking system for low‐light, naturalistic conditions. Offspring did not differ significantly in replicate silent versus singing fitness conditions was associated increased locomotion both sexes. Our results provide evidence that flexible behaviour can promote adaptation via reproductive output suggest rapid evolution animal systems may be less constrained than previously appreciated.

Sex-biased gene expression, particularly sex-biased expression in the gonad, has been linked to rates of protein sequence evolution (nonsynonymous synonymous substitutions, dN/dS) animals. However, insects, studies remain centred on a few holometabolous species. Moreover, other major tissue types such as brain underexplored. Here, we studied and hemimetabolous insect, cricket Gryllus bimaculatus. We generated novel male female RNA-seq data for two sexual types, gonad somatic reproductive system, core components nervous ventral nerve cord. From genome-wide analysis, report several findings. Firstly, testis-biased genes had accelerated evolution, compared ovary-biased unbiased genes, which was associated with positive selection events. Secondly, although were much less common than they exhibited striking tendency rapid an effect that stronger brain. Further, some functions mating behaviours, suggest may have their via selection. Thirdly, narrow cross-tissue breadth, suggesting low pleiotropy, observed relaxed purifying selection, speculate allow enhanced freedom evolve adaptive functional changes. The findings female-biased are discussed respect biology this cricket.

How emerging adaptive variants interact is an important factor in the evolution of wild populations, but opportunity to empirically study this interaction rare. We recently documented emergence phenotype “curly-wing” Hawaiian populations field crickets ( Teleogryllus oceanicus ). Curly-wing inhibits males’ ability sing, protecting them from eavesdropping parasitoid flies Ormia ochracea Surprisingly, curly-wing co-occurs with similarly protective silent “flatwing” phenotypes multiple which neither has spread fixation. These two are frequently coexpressed, since either sufficiently reduces song amplitude evade fly, their coexpression confers no additional fitness benefit. Numerous “off-target” phenotypic changes known accompany flatwing, and we find that curly-wing, too, negatively impacts male courtship affects mass survival females under lab conditions. show through crosses genomic mRNA sequencing expression associated variation on a single autosome.

By combining insights into genetic architecture these alternative simulations observations, co-occurrence adaptations impedes fixing, despite extreme benefits, due epistasis.
