BackgroundVery little is known on how changes in circadian rhythms evolve. The noctuid moth Spodoptera frugiperda (Lepidoptera: Noctuidae) consists of two strains that exhibit allochronic differentiation in their mating time, which acts as a premating isolation barrier between the strains. We investigated the genetic basis of the strain-specific timing differences to identify the molecular mechanisms of differentiation in circadian rhythms.ResultsThrough QTL analyses we identified one major Quantitative trait chromosome (QTC) underlying differentiation in circadian timing of mating activity. Using RADtags, we identified this QTC to be homologous to Bombyx mori C27, on which the clock gene vrille is located, which thus became the major candidate gene. In S. frugiperda, vrille showed strain-specific polymorphisms. Also, vrille expression differed significantly between the strains, with the rice-strain showing higher expression levels than the corn-strain. In addition, RT-qPCR experiments with the other main clock genes showed that pdp1, antagonist of vrille in the modulatory feedback loop of the circadian clock, showed higher expression levels in the rice-strain than in the corn-strain.ConclusionsTogether, our results indicate that the allochronic differentiation in the two strains of S. frugiperda is associated with differential transcription of vrille or a cis-acting gene close to vrille, which contributes to the evolution of prezygotic isolation in S. frugiperda.Electronic supplementary materialThe online version of this article (doi:10.1186/s12862-017-0911-5) contains supplementary material, which is available to authorized users.

“…Measuring patterns in mosquito flight activity often consists in the manual scoring of behavioral attributes (Noldus, 1991), or video recording of behavioral sequences, using a video camera and computer assisted analyses (Cummins et al, 2012;Jones, 1964;Reiser, 2009), or has previously been achieved by the use of flight mills (Nakamori and Simizu, 1983), break-beam technology (Gentile et al, 2009;Rund et al, 2012) or acoustic measurements in specialized sound-proof flight cages (Nayar and Sauerman, 1971). However, none of the widely used assays is universally adapted or accessible for the quantitative investigations of flight activity of male A. albopictus, because they are either subjective, invasive, require specialized equipment or give results that are not reproducible.…”

“…Rivas et al. (2008) , Rund et al (2012) ], this scenario configures an exciting opportunity to link genetic and phenotypic variation, which might lead us to better understand the molecular underpinnings of the circadian clock, its variation and how plasticity is achieved. As the clock is fundamentally important to every aspect of behaviour and physiology of almost all higher organisms, the circadian analysis of insect vectors, given their epidemiological importance, must not be undervalued by the vector community.…”

Organisms from bacteria to humans have evolved under predictable daily environmental cycles owing to the Earth’s rotation. This strong selection pressure has generated endogenous circadian clocks that regulate many aspects of behaviour, physiology and metabolism, anticipating and synchronising internal time-keeping to changes in the cyclical environment. In haematophagous insect vectors the circadian clock coordinates feeding activity, which is important for the dynamics of pathogen transmission. We have recently witnessed a substantial advance in molecular studies of circadian clocks in insect vector species that has consolidated behavioural data collected over many years, which provided insights into the regulation of the clock in the wild. Next generation sequencing technologies will facilitate the study of vector genomes/transcriptomes both among and within species and illuminate some of the species-specific patterns of adaptive circadian phenotypes that are observed in the field and in the laboratory. In this review we will explore these recent findings and attempt to identify potential areas for further investigation.
